Auro Weaving Humidifies With Condair Jetspray

Auro Weaving Humidifies With Condair Jetspray

Condair Limited

Auro Weaving Mills in Baddi, India, has installed a JetSpray humidification system from Condair to humidify its warping section. The humidifier is creating the ideal air humidity to reduce fibre shedding from the yarn and airborne fly, as well as maintain yarn moisture content and minimise yarn breakage during processing.Auro Weaving Mills is a unit of the Vardhman Group, which has 22 manufacturing facilities across India and employs more than 25,000 people. The Auro factory manufactures the highest quality fabric from its 288 airjet looms and produces over 388 lakh (38.8M) mtrs of fabric per year.Mukesh Saxena, Chief General Manager of Fabric Operations at Vardhman, explains, “The JetSpray is maintaining the ideal humidity of 60%RH in Auro Weaving’s warping section. This significantly reduces the generation of fly and yarn breakages, helping us to deliver the highest efficiency and quality in the department.“Since we installed the JetSpray humidification system, the ambience of the area is very comfortable and clean. The reduction in yarn breakages not only results in a more trouble-free operation at subsequent stages but also boosts the morale of the employees, as less rethreading is required. We would highly recommend the JetSpray for humidification in warping and yarn storage, where reliable and accurate humidity control is essential.” Mr Saxena concludes.The JetSpray system installed at Auro Weaving Mills incorporates 66 nozzles, each capable of introducing 4.5 litres of moisture per hour into the atmosphere. A wall-mounted JetSpray control panel regulates a supply of compressed air and water, which is provided to the nozzle lines. Each nozzle perfectly combines the air and water to release extremely fine aerosols, with droplet sizes of just 7.5 microns, which rapidly evaporate into the air. The compressed air prevents any possibility of drips from the nozzles and makes the spray highly directional, thus preventing wetting on machinery, walls or the floor.The JetSpray humidifier was provided and installed by Condair’s representative in the Indian textile sector, Regent Machine and Servicing (RMS). Jaydeep Dasgupta, Managing Director at RMS, commented, “As the JetSpray introduces moisture at many points across the room, the humidity level throughout an area can be precisely regulated. This is unlike centrally ducted air washers, which frequently struggle to maintain optimum humidity levels across a complete production area. As a single JetSpray control panel can provide up to 600 litres of humidity per hour, it is an ideal system for large textile factories or for topping-up humidification provided by existing ducted systems.”Mr Dasgupta, continues. “We are very proud to be working with the Vardhman Group on this project at Auro Weaving Mills and in helping Vardhman maintain the utmost product quality for which they are world-renowned. The JetSpray humidification system is proven technology in the textile and jute sectors, and RMS has undertaken over 200 installations across the subcontinent. Modern high-speed textile machinery requires superior humidity control and the JetSpray from Condair is versatile and adaptable to virtually any humidification requirement.”
Biltong drying success with Condair & JTR

Biltong drying success with Condair & JTR

Condair Limited

Specialist South African food supplier, The Savanna, is using Condair dehumidifiers to dry its award winning biltong at its production facility in London. Two Condair dehumidifiers were installed by John Todd Refrigeration (JTR) to help in the production of this traditional South African product.Biltong is a dried and cured meat, with a rich and dense flavour, which is cut into strips and often eaten as a snack. The Savanna’s biltong is produced using grass-fed beef from the Scottish highlands and a traditional South African curing method. Silverside beef slabs are sliced into strips and then marinated before being mounted on hooks for air drying, which is where Condair’s dehumidifiers assist in the process.Matt Gough, Refrigeration Engineer at JTR commented, “The Savanna approached JTR wanting to improve the consistency and efficiency of their drying rooms, whilst also gaining better control over what was happening inside. The rooms need very tight environmental control but the previous strategy introduced outside air to help lower temperatures when needed. This external factor meant that the internal room conditions, and therefore the drying process, were influenced by the seasons and weather.”“JTR redesigned the drying rooms and installed Condair DC-N dehumidifiers. The dehumidifiers, located in the rooms, both dry and heat the air to the required condition, resulting in a fully sealed area and a consistently controlled drying process.” Matt concluded.Lisa Gardshol, founder and CEO of The Savanna, commented, “We have been very happy with the performance of the Condair dehumidifiers JTR installed to comply with our drying approach. It has not only allowed us to increase production efficiency but also produce our award-winning biltong. We have full control over the entire process and can make decisions based on the data that we recieve. This is something which we couldn’t do as well before.”“The Savanna now operates several drying rooms at our London production facility and we are able to monitor the entire activity accurately. During the drying process, the beef will lose around 50% of its weight in moisture loss, so the dehumidifiers are each removing several hundred litres of water per cycle. We’ve found that this ratio leads to the best-tasting biltong” Lisa concludes.As well as manufacturing, The Savanna imports and distributes a wide range of South African food and drink products in the UK. It operates eight retail outlets at train stations across London, including Victoria, Liverpool Street and Paddington, and delivers nationwide via its websites at thesavanna.co.uk and m-eat.co.uk.John Todd Refrigeration specialises in design and planning of bespoke refrigeration installations, which are supported by 24 hour service and maintenance back-up. The Exeter-based company was established in 1998 and serves the UK's food, hospitality and retail sectors.The Condair DC-N dehumidifiers installed by JTR at The Savanna, are part of an extensive range of dehumidifiers offered by Condair. The company supplies both condensing and desiccant technology, with a wide range of capacities and many pre- and post- drying features, to ensure process air delivery precisely matches an application’s requirements.
Condair has a gas at BAT Southampton

Condair has a gas at BAT Southampton

Condair Limited

Condair has supplied two gas-fired humidifiers capable of delivering up to 480kg of steam per hour to British American Tobacco’s R&D facility in Southampton. Seeking an energy efficient alternative to their existing 10 year old live steam humidification system, the Condair GS gas-fired humidifier proved the perfect replacement as it provides high capacity steam generation with low operating costs, offering 65% cheaper steam than electric humidifiers.Two Condair GS humidifiers were installed, each capable of delivering up to 240kg of steam per hour to two AHUs feeding a test area which needed to be kept at a constant 22°C with 60%RH ±5%. Steve Hemsley, Head of Commercial at British American Tobacco, commented, “To date the humidifiers have enabled us to maintain the desired conditions in our close conditioned environments.”Condair GS gas-fired steam humidifiers have a high quality, compact construction with state-of-the-art safety features, a user-friendly design and a variety of flexible options which makes them simple to install and straightforward to service and maintain.The humidifier incorporates a 360° flame encircling the burner. This maximises the thermal transfer to the heat exchanger resulting in a thermal efficiency of over 90%. The Condair GS therefore reacts very quickly to a requirement for humidification whilst minimising gas consumption and emissions. Steam output can also be consistently controlled from outputs as low as 10kg/hr.The stainless steel heat exchanger has large flat surfaces that dislodge scale during normal operation. This scale falls to the bottom of the water tank. The large flat surfaces of the heat exchanger make it easy to remove what little scale is left behind. Also, as the heat exchanger remains mostly scale-free, the efficiency of heat transfer to the water is maximised. To further reduce scale build-up in the boiling chamber, a low volume of fresh water is continually added and high mineral content water removed. This not only decreases scale build-up but improves humidity control when compared to other gas-fired humidifiers that occasionally stop steam production and run a complete tank drain to combat scale.Alongside the humidifiers Optisorp short evaporation steam lances were also supplied to distribute the steam inside the ducts. Made from stainless steel, giving a long service life, the OptiSorp steam distribution manifold offers evaporation distances up to four times shorter than standard steam pipes. Multiple distribution pipes provide steam across the entire duct at a very even concentration. The pipe’s outlets have tiny tubes that take the steam from the centre of the pipe where it is at its hottest and driest, assisting rapid absorption.
Condair Helps Cool Microsoft Dublin Data Centre

Condair Helps Cool Microsoft Dublin Data Centre

Condair Limited

Condair has supplied 35 evaporative humidifiers to Microsoft’s $500 million mega data centre in Dublin, Ireland, to provide up to 8°C of low energy evaporative cooling to its enormous data halls.Microsoft Dublin is the latest generation of data centre that use “free air cooling” rather than mechanical chillers to maintain the low internal temperatures required around its servers. Fresh air is continually brought into the building and mixed with the re-circulating inside air. The majority of the evaporative humidifiers are situated inside the air handling units located on the roof of the data centre. During the summer months, when the outside temperatures are high, the warm incoming fresh air is fed through the humidifiers, which evaporate moisture into the air stream reducing its temperature.This combined use of fresh air and evaporative cooling has enabled the data centre to eliminate the need for mechanical cooling for 95% of the year. The Microsoft Dublin data centre has officially been recognised by European Commission’s Sustainable Energy Europe Campaign as a “best practice” in environmental sustainability design through its innovative design, which has made it 50% more energy efficient than traditional data centres built three years ago.The 35 evaporative humidifiers installed have the capacity to provide up to 10,930 litres of moisture per hour to the airstream feeding the 303,000 sq ft facility. The evaporating water produces an adiabatic cooling effect on the air, reducing its temperature by up to 8oC. The system was designed to reduce the incoming air from a maximum of 26°C in the summer to the room supply temperature of 18°C. Even at maximum output the total energy required to provide this level of evaporative cooling is just 17kW across all the humidifiers in the facility.The humidifiers were supplied in two phases to the air handling unit manufacturers, with the initial 24 being installed by Johnson Controls and the remaining 11 by RMI Engineering. The main building contractor on the project was John Sisk & Son Ltd with the design being carried out by Integrated Design Consultants and PM Group.
Condair Helps The Vyra Hotel Create The Perfect Atmosphere

Condair Helps The Vyra Hotel Create The Perfect Atmosphere

Condair Limited

The palatial Vyra Suites Hotel in Qatar, has installed four dehumidifiers from Condair to create the perfect “blue sky” atmosphere for guests enjoying its luxury indoor swimming and hydro pool areas. The dehumidifiers are creating the ideal air humidity of 60%RH to prevent moisture evaporation from the pools causing condensation in the area or an uncomfortably humid environment.The installation was carried out by Mentor Trading and was part of a recent refurbishment of the 44-storey luxury property, which is part of the NH Collection Hotel Group and is located in West Bay, Doha's prominent business district. The four Condair DP-C 200 condensing dehumidifiers are ceiling mounted systems, each capable of extracting up to 190 litres per day (@30°C/80%RH).Kiran Nair, Sales Engineer at Mentor Trading commented “The ceiling mounted dehumidifiers are compact in size and were fixed above the pool and spa areas, in an upper floor. Air grilles, which extract humid and return dry air, are discretely located above the swimming pools, in a painted, cloudy-blue-sky ceiling scene, designed to further enhance the relaxing spa environment.”Kiran, continues. “We were very satisfied with Condair’s service and their prompt response to the project. The quality of the Condair DP-C dehumidifiers is of a high standard and they were easy to install and simple for the customer to operate. We look forward to a working with the Condair team in the future”.This type of ceiling mounted system is particularly suitable for commercial applications with limited space, like indoor pools and spa areas. All sound-emitting components, such as compressors and fans, are located away from the public area, thus keeping noise to a minimum. Servicing can also take place without disrupting business operations.Condair’s Middle East General Manager, Mahmoud Widyan, commented. “We are very proud to have provided the dehumidification units for this project at the Vyra Suites Hotel and to have worked with Mentor Trading to help maintain the highest quality atmosphere for this first class hotel. The Condair DP-C dehumidification system is proven technology, specifically designed for indoor pool areas. It protects against condensation and associated issues it can cause, such as corrosion. The Condair DP-C also has the option to use heat produced in the dehumidifying process to heat the pool water, thus saving energy. Hotel operators with indoor swimming pools should always insist on a contemporary and efficient dehumidification system being installed, such as the Condair DP-C.”
Condair Humidi-Tea Perfection at Sabuj Agro Industries

Condair Humidi-Tea Perfection at Sabuj Agro Industries

Condair Limited

The Sabuj Agro Industries tea factory in Bangladesh has installed a Condair JetSpray humidification system to maintain the perfect humidity in its production facility and ensure the highest quality black tea. By maintaining a high humidity in the factory, moisture loss from the cut tea leaves is significantly reduced. This improves the fermentation process, resulting in a blacker, more flavoursome tea with improved liquor characteristics and a higher market value.Condair’s representative in India, Regent Machine & Servicing, managed the design of the humidification system along with its supply and installation. Jaydeep Dasgupta, Managing Director at Regent Machine commented, “Air humidification is a proven method for enhancing the profitability of a tea production facility. By maintaining a high ambient humidity with a JetSpray humidifier, moisture loss from the tea is virtually eliminated during fermentation. As the moisture content in the tea leaf is kept higher, the chemical reactions that occur during oxidation are enhanced, producing a product with a better final taste, strength and colour.“Most CFM machines have built-in humidifiers that pass humidified air through the tea from below. However, these systems are not adequate to prevent drying, particularly from the layer on the top, which is exposed to the room’s atmosphere. Losses of up to 10% are not uncommon even on humidified CFMs. This moisture loss will inhibit the fermentation process and result in a poorer quality product with a lower value. It also increases the volume of secondary refuse tea, as more tea degrades from being granular to dust during production.” Mr Dasgupta concludes.The JetSpray humidifier consists of a control panel and a series of nozzles, which can be mounted throughout the area to be humidified, as well as on the in-duct manifold, as a retrofit replacement of the CFM’s original, inefficient in-duct humidifier. The precision engineered nozzles combine compressed air and water, which when released create a very fine and highly directional aerosol. The compressed air ensures the moisture rapidly evaporates without any risk of wetting in the area or on machinery within the room. The fan-free design means the JetSpray can operate in very industrial, dusty environments without problems. The nozzles have a self-cleaning mechanism that prevents blockages and the humidifier can operate with any potable water quality without the need for highly filtered, mineral-free water.The Sabuj Agro Industries tea factory is located in Atwari Upazila, Bangladesh. The system installed at the factory has 32 nozzles humidifying the air to 75-80%RH in the CTC area, and 60 nozzles maintaining 90-95%RH in the fermentation area. In total the complete system is capable of providing up to 678 litres of humidity per hour to the atmosphere inside the factory. Sabuj Agro’s owner decided to invest in the JetSpray, and replace an existing spinning disc system, after seeing the JetSpray successfully controlling the humidity at the nearby Bajrang tea factory located, across the border in West Bengal, India.
Condair humidification at Jaguar Land Rover

Condair humidification at Jaguar Land Rover

Condair Limited

Condair has supplied and installed four evaporative humidification systems to Jaguar Land Rover for use in its exhaust emissions testing facility at the company’s Product Compliance Centre in Solihull. The evaporative humidifiers provide humidity control to two rolling-road engine test cells to ensure compliance with international environmental parameters.Jaguar Land Rover carries out quality control tests on every vehicle before it is despatched. The strict exhaust emission testing must be carried out within a temperature range of 20 to 30°C and a moisture level between 5.5 and 12.2g/kg of dry air.The evaporative humidifiers are replacing several electric steam humidifiers that were proving costly for Jaguar Land Rover to operate in terms of energy and parts. The humidification systems provided by Condair offers much lower running costs without the high maintenance inherent in steam systems.An evaporative humidifier consists of an evaporative module located inside an air handling unit with an external control panel. The evaporative module is a fully bonded particle-free matrix through which the air passes. Water is delivered to the top of the matrix and flows down its corrugated surface. As air passes through, it increases in humidity and is cooled.Rather than heating water with electricity to create steam, as the previous electric steam humidifiers did at Jaguar Land Rover, the air prior to the evaporative humidifier is heated by a gas-fired boiler. The warm dry air then absorbs moisture from the humidifier to reach the set humidity. The same amount of overall energy is required but the economy of using gas rather than electricity as a heat source makes the energy cost around 60% less than electric steam humidifiers.Evaporative humidifiers can operate on mains or demineralised water and can be located in short sections of an AHU as it provides instant evaporation. Unlike steam humidifiers that need regular maintenance to combat scale build-up, the scale that is left behind after evaporation from the matrix is simply washed to drain, reducing maintenance and operating costs.
Condair humidifiers at the National Army Museum

Condair humidifiers at the National Army Museum

Condair Limited

Condair has recently supplied and installed three Condair RS resistive steam humidifiers to maintain the humidity around the exhibits and archives at the National Army Museum in Chelsea, London.Optimum environmental conditions are required to ensure the perfect preservation of military artefacts that are made of a wide range of materials, some of which date back to the English Civil War.Mike O’Connor, Deputy Director at the National Army Museum, commented, “Precise climate control in our galleries and stored collections, across both temperature and humidity, plays an important role in preserving the nation’s military heritage. Our collections include an array of exhibits, from the cloak Wellington wore at Waterloo and Lawrence of Arabia’s dagger to modern day grenade launchers and drones. Metals, textiles, wooden objects and paintings can all be affected by high or low humidity, so a stable environment ensures longevity and avoids costly restoration work.”The three Condair humidification systems were installed in weatherproof enclosures on the roof of the museum as part of its recent £24M refurbishment project. As well as resisting the London weather, the Condair enclosures incorporate a heater and fan unit to ensure the internal conditions remain within the humidifier’s recommended operating range. So, just as the humidifiers help the museum preserve its exhibits, likewise the enclosures do the same job for the humidifiers.The Condair RS resistive steam humidifier is the ideal choice for heritage applications due to its responsive control and innovative scale management system. It can operate on mains water, as it is at the National Army Museum, and provide ±3%RH control, or on RO water and offer a close ±1%RH control. A humidifier that gives rapid response and close humidity control is important for museums that can be empty one minute and full of tourists in from the rain the next.A patented scale management system on the Condair RS allows in-house maintenance teams to undertake routine scale removal, safely and quickly, without even needing to open the humidifier’s main cabinet. A scale collector tank is located under the boiling chamber, into which scale falls during operation. Scale removal is a simple process of draining the unit with the push of a button, disconnecting the cooled collector tank and emptying it.The National Army Museum is the leading authority on the British Army and its impact on society past and present. It displays thousands of pieces across five themed galleries with a special temporary exhibition gallery, event space, a café and children’s area, Play Base. Admission is free to the permanent galleries and the Museum is open to the public between 10am and 5.30pm, daily.
Condair Humidifies Facebook Data Centre, Lulea, Sweden

Condair Humidifies Facebook Data Centre, Lulea, Sweden

Condair Limited

Facebook’s data centre in Luleå Sweden is one of the World’s most efficient and sustainable data centres. It is powered with locally generated hydro-electric energy and uses the cold Nordic air to cool the servers that store Facebook users‘ photos, videos, comments and Likes.In keeping with its state-of-the-art efficiency, the facility is using Condair's low energy high-pressure spray system and evaporative humidifiers to maintain the humidity inside its data halls.Peter Liddle, associate at Cundall, one of the consulting M&E engineers for the project, explains, “Facebook Luleå is employing a direct air cooling strategy within their data halls, which uses the cold outside air to maintain the required internal temperature. Luleå’s cold dry climate means that humidification is an essential component within the air conditioning process as without it the internal humidity could drop as low as 2%RH.“This low level of humidity would be unhealthy for staff and present an increased risk to the servers from electro-static discharge.”Once the cold outside air is brought into the building, it is mixed with hot air re-circulated from the data halls, raising the temperature but reducing its humidity. 78 spray and evaporative humidifiers then add up to 22,800 litres of water per hour to the air stream flowing through the building’s “penthouse ventilation” systems. This produces the ideal humidity while lowering the temperature back to the required supply condition for introduction to the data halls.Condair humidifiers deliver this huge volume of moisture to the atmosphere while consuming just 90kW/h of electrical energy in total. 
Condair Humidifies Polestar Sheffield

Condair Humidifies Polestar Sheffield

Condair Limited

A Condair ML Solo high pressure humidification system has been installed in the litho platemaking area at Polestar print company’s award-winning plant in Sheffield. Designed to suppress and disperse electrostatic charges when protective film is removed from the plates, Condair’s low-energy humidifier maintains a relative humidity of 45% in the area. The project was carried out by Cambridgeshire-based HVAC and process engineering specialist, Arcade.Polestar Sheffield produces 2.5 million high-quality catalogues, magazines, brochures and newspaper supplements every day. Part of Polestar Group, the company produces many well-known titles including Cosmopolitan, Radio Times, Woman’s Own, Country Life and many Sunday newspaper supplements.With a strong focus on printing excellence and productivity at Polestar, the new humidifier installation provides an effective solution to the problem of electrostatic charge generation when protective paper is removed from the litho plates. By reducing and dissipating the electrostatic charge, the paper and plates are easier to handle, it prevents the attraction of dust and reduces the risk of spark generation. The Condair ML humidifier delivers ultrafine sprays directly into the air, which rapidly evaporate to maintain a relative humidity of 45%RH, the level required to counter the effects of static electricity.Joss Williams, Arcade’s Senior Project Manager, said, “The humidifier meets Polestar’s requirements and the customer is happy. Previous experience of Condair as JS Humidifiers has been good”. When it came to this installation, the versatility of the system and working knowledge of the installation team proved important. Joss Williams continues, “The guys that attended site changed the design to suit the site location with no issues in relation to price. The installation was of a high standard and looks good”.The Condair ML Solo is a low energy, cold water spray humidifier, requiring just 5% of the energy used by equivalent steam humidifiers. This fits well with Polestar’s strong environmental credentials, which seek to minimise its impact on the environment through initiatives such as recycling and wastewater management.Ten spray heads are located in the platemaking area, with a capacity to deliver up to 48 litres of pure, demineralised water into the air each hour. Effective moisture distribution is ensured from the twin jets on each ML Solo unit by a low energy, low noise fan. Operating in complete safety at 70bar, the jets are fed with mineral-free water produced centrally by a Condair MLPRO100 pump and reverse osmosis treatment station. The system features a stainless steel, oil-free, high-pressure pump, RO water purification and UV water sterilisation, so low maintenance and pure, hygienic sprays are guaranteed. Pipework is in stainless steel and high grade corrosion-free flexible hoses.Arcade’s work at Polestar Sheffield has included the installation of two chillers, inverter-controlled chilled water pumps, pumping stations, tanks and over 3km of stainless steel pipework, with Condair undertaking the installation of the humidification system on behalf of Arcade.Condair’s ML Solo humidifier is widely used in the printing industry around the world, particularly in paper storage, press halls and print finishing. An environment of 45-55%RH effectively deals with problems caused by dry air such as tight edges, paper curl, misfeed and web breaks, and effectively disperses ‘static and dust. In an industry where temperatures can get high, the cold water humidifier also offers the benefit of free cooling - up to 33kW from a system like the one at Polestar. It is also widely used for humidification and evaporative cooling in many other industrial applications such as woodworking and textiles, commercially in horticulture, in applications such as supermarkets to maintain the quality of fresh vegetables, and in offices.The spray head operation is virtually silent, introduces no dust to the atmosphere, is hygienic and requires only infrequent and straightforward maintenance. With a choice of colours, jet configuration and outputs, with adjustable brackets for directional orientation, they can be ceiling- or wall-mounted and suit many situations.
Condair Humidifies the Green Planet, Dubai

Condair Humidifies the Green Planet, Dubai

Condair Limited

Condair, has supplied and installed a high pressure humidification system to help protect the flora and fauna inside The Green Planet biodome in Dubai. This exceptional indoor rainforest contains over 3,000 species, including insects, plants, fish and mammals. A Condair ML humidification system is spraying up to 750 litres per hour to recreate an indoor tropical habitat at the centre.Victoria Lynn, General Manager Attraction at The Green Planet - Dubai Holding Entertainment, commented, “We need to maintain a humidity range of 70-90% throughout the year. We keep the temperature at between 24-26°C inside the rainforest biome year-round. Keeping the biome within this humidity and temperature range is important, as we have numerous species of rainforest plants and animals that depend on a proper environment to survive and live a comfortable life.”Victoria continues, “Some general consequences of not maintaining the required humidity and temperature include plants drying out, or not having enough water. Our birds require high humidity to keep their feathers and skin clean and healthy. For our reptiles, high humidity helps them to shed their skin properly and prevent dehydration.”Mahmoud Widyan, General Manager at Condair Middle East commented, “The Green Planet biodome is such an impressive and educational experience for its guests, and we are very proud to have supplied the humidification system for this project. It was important that the humidifiers blended in with the design of the environment, so we worked with the project team to embed the system’s nozzles around some of the elevated walkways that surround the world’s largest man-made tree. It was a very successful installation, which we are delighted to be supporting with regular planned preventative inspection and maintenance.”The ML Flex high pressure humidifier used at the center is proven technology and consists of a water treatment and pump station feeding water to a series of nozzles strategically located in the area requiring humidity control. As the water is pressurized to around 70 bar, when it is released from the nozzle, it rapidly atomizes without any drips. Its RO water treatment filter removes not only minerals from the supply water but also bacteria and viruses. This combines with the humidifier’s on-board UV sterilisation system to ensure humidification is dust free and hygienic.High pressure humidifiers, such as the ML Flex, offer high capacity humidification as well as evaporative cooling to an environment. For every 1kg of moisture delivered, 0.68kW of evaporative cooling is also provided. As each pump station can provide up to 750kg/h of water, the system is ideal for large manufacturing and production areas, as well as greenhouses and agricultural applications.
Condair JetSpray humidifies at Fujifilm

Condair JetSpray humidifies at Fujifilm

Condair Limited

A Condair JetSpray humidification system is maintaining an ideal 40-60%RH (relative humidity) at the Fujifilm Imaging and Innovation Centre in Bedford. The JetSpray has been installed to provide Fujifilm’s demonstration area, which incorporates the latest Jet Press 720s, with the optimum atmospheric conditions for paper storage and printing.When exposed to dry air, paper loses its internal moisture rapidly, causing its physical shape to change, which can result in problems when it‘s run through a printing press. Electrostatic issues are also greatly increased when air humidity drops below 40%RH.Steve Freeman, Jet Press Solutions Manager at Fujifilm “Humidity control is important for paper handling consistency when running lighter weight stock on the Jet Press 720S in both the feeder and jetting area.We aim to maintain an RH of between 40% and 60%. Below this could potentially cause an increase in paper handling issues on light weight paper”. Since the installation of the Jetpray, Steve said, “Once the humidifier was up and running correctly, it has performed well. It now easily and quickly gets the room up to the required RH and maintains this after start-up”.The Fujifilm Imaging and Innovation Centre offers its UK customers demonstrations and training on the Jet Press printer and a range of wide format UV units including LED UV and conventional Flatbed UV inkjet printers.The JetSpray humidifier consists of a control panel feeding compressed air and water to rows of self-cleaning spray nozzles mounted in the area to be humidified. The compressed air atomises the water as it is released from the nozzle, creating a very fine aerosol that rapidly evaporates. The nozzle design ensures that water can only be introduced when compressed air is flowing, guaranteeing drip-free humidification. The system has a fully modulating output and offers very close humidity control at ±2%RH.Regular and automatic flush cycles ensure hygienic operation by preventing water from remaining in the system to stagnate. A PureFlo Ag+ silver ion dosing system is also incorporated on the incoming water supply. Silver has powerful antibacterial properties and provides a strong residual effect throughout the water pipe work.The JetSpray has standard plumbing fittings so is easy to install for any competent HVAC contractor. It can run on mains, demineralised or softened water and due to a self-clean pin in the nozzle, requires very little maintenance.
Condair keeps Christ's Hospital organ in tune

Condair keeps Christ's Hospital organ in tune

Condair Limited

Condair has supplied a Condair CP3 steam humidifier to humidify the school hall organ at Christ’s Hospital School near Horsham, ensuring it resonates correctly and remains in tune whatever the weather.The organ in Christ’s Hospital’s ‘Big School’ is of huge historical importance and great artistic merit. It has its roots in an organ built in 1830 by Elliot & Hill and around 25% of the current pipes date from the original instrument. It was substantially renovated in 1902 and then again in 2012 when a specialist in organ restoration recommended installing humidification and suggested Christ’s Hospital talks to Condair s because of the company’s expertise in this area.Large pipe organs need to have the humidity maintained within their organ chambers in order to preserve the wooden sound boards and sliders. If the air in the organ chamber becomes dry then it will draw moisture from the surrounding wood causing it to suffer dimensional changes. This can cause the sliders to warp and stick, resulting in an unresponsive instrument. By maintaining 55% relative humidity (%RH), the wood is in equilibrium with the air and it retains its moisture content and shape. This is often achieved with small capacity steam humidifiers, like the Condair CP3, which feed steam directly into an organ chamber through a fan unit.Peter Dutton, the school organist at Christ’s Hospital commented: “Condair clearly had experience in working with such ancient and delicate organs and was quickly able to propose the most suitable model, as well as its positioning for installation. It has made a real difference in keeping the humidification in the organ chamber stable and we are now able to play the organ whatever the weather is like outside; even during the cold, dry conditions of last winter.”The Condair CP3 is an electrode boiler steam humidifier that can deliver steam to an air handling unit or directly to a room’s atmosphere. All steam humidifiers require occasional servicing to remove limescale that builds up during operation. The Condair CP3 makes servicing quick and easy as the boiling cylinder is disposable. When servicing is required the cylinder is simply drained, removed and replaced with another, keeping downtime to a minimum.The humidifier incorporates innovative features, such as water conductivity monitoring and staged electrode use, to maximise the lifetime of the cylinder. It is available in sizes from 5-90kg/hr and can operate with standard mains water.Condair has humidified some of the most prestigious concert halls and pipe organs in the world including those at The Sydney Opera House, The Royal Albert Hall, Alexandra Palace and the Royal Opera House in Covent Garden.
Condair ME helps EDPAC cool at CIX

Condair ME helps EDPAC cool at CIX

Condair Limited

The Condair ME evaporative humidifier is providing adiabatic cooling in an innovative indirect cooling system from EDPAC at the Cork Internet Exchange (CIX) in Ireland. EDPAC’s indirect air-to-air evaporative cooling system will be maintaining the temperature across CIX’s data halls without using any chillers and with 75% less energy than a traditionally cooled data centre.The installation of the new low energy cooling system was part of a €6M extension at the family–owned 2,800sqm data centre, partly funded by the Excellence in Energy Efficient Design (EXEED) programme.The EDPAC air handling system cools without chillers by creating two airstreams; one internal and one external. The internal airstream circulates air to and from the data halls and the external airstream draws in, then vents, ambient outside air. Both airstreams pass through a series of heat exchangers to transfer cool thermal energy from the external to the internal airstream, without either physically mixing.In order to boost the cooling capacity of the system, and keep the data halls at 24°C all year round, evaporative cooling is used to reduce the temperature of the external airstream below that of the ambient outdoor air. A series of Condair ME evaporative humidifiers are located in the walls around a penthouse ventilation area, created across the top storey of the building. As air is drawn into the building through louvres, it passes through these Condair MEs, before entering the penthouse ventilation area where the EDPAC AHUs are located.The Condair ME consists of an evaporative matrix section, which sits across a duct, and a hydraulic module that continually pumps water up to the top of the matrix to keep it moist. As air travels through the Condair ME’s wet matrix, it absorbs water and is cooled by several degrees.Noel Lynch, managing director at EDPAC, comments, “By reducing the temperature of the outside air entering the penthouse ventilation area with the Condair MEs, the air being drawn into the external airstream of the air handling units is significantly cooler than the outside air. This enables the indirect cooling system to maintain the desired data hall temperature of 24°C, even in the hottest months of the year.”Noel continues, “The complementary technologies of air-to-air heat exchange and humidifier-based evaporative cooling is a considerable improvement to existing indirect data centre cooling systems. The strategy offers very low energy climate control while being easy to manage, as it doesn’t have a wet spray section with the onerous administrative obligations that this can place on a building operator.”Four AHU modules, each delivering up to 400kW of cooling, have been installed above the data halls at CIX, alongside four Condair ME evaporative humidifiers. While the outside Cork weather remains below 21°C, air-to-air cooling alone is sufficient to maintain the required data hall condition. When the outdoor temperature rises above this, the Condair MEs operate to provide up to 300kW of cooling to each AHU.Donal Deering, energy consultant at Smart Power, the Dublin-based energy consultancy that worked on the project, commented, “The expected electrical demand across the year is just 12kW per 400kW AHU module, including the electrical consumption of the Condair ME evaporative humidifiers. Typical PUE values across Irish data centres is 1.5-1.7 but the use of adiabatic cooling at CIX will lower the facility’s overall PUE to less than 1.4. The energy savings are expected to be 75% of that which would otherwise be used in a traditionally cooled data centre.”Donal concludes, “The CIX evaporative cooling project is an exciting, innovative project and credit must go to Jerry Sweeney, Chief Executive at CIX, and Noel Lynch at EDPAC for their pioneering efforts.”
Fire training centre home & dry with Condair

Fire training centre home & dry with Condair

Condair Limited

Firefighters at the new training centre of the Cheshire Fire and Rescue Services at Winsford are benefiting from a Condair dehumidifier to dry out their protective kit at the end of each wet training exercise. The equipment was specified by T Clarke, one of the UK’s leading building service companies, for the centre’s drying room as part of the new build project.Equipment ensuring the strict control of moisture in a drying room is essential to save firefighters’ gear from the effects of water damage after a call-out or a training exercise. It’s vital that they have access to a drying facility to prevent extensive damage and potentially significant replacement costs for the fire service. Condair supplied T Clarke with a Condair DC 50W wall-mounted unit that had to be in place at the Centre within one day of arriving on site prior to handover to fire chiefs. This timescale proved no problem as the dehumidifier was tailor-made for the job and was easily installed by the contractor’s engineers.T Clarke’s Project Engineer, Doug Lumb, explained: “A new build project like this is really quite exciting with the scope to start from scratch. The Condair DC 50W dehumidifier was actually chosen by our designers, as it fit the bill perfectly for the environment. The unit size was based on the quantities of kit hung in the room to dry when the firefighters return to the Centre at the end of their training exercises. It’s a reliable product and currently operating at the station just as expected, plus installation was really simple and didn’t take long at all, so all very good. I would definitely specify Condair dehumidifiers for future projects.”The Condair DC 50W is part of a range of condensing dehumidifiers that offer powerful drying performance. It is easy to install and has an attractive galvanised sheet metal cover with powder enamel finish. The wall-mounted versions can be supplied with steel feet for extra stability. As well as the built-in digital user interface, the dehumidifier has an optional remote wall controller, which can be located up to 50m away. Remote mechanical hygrostats are also available.The unit installed by T Clarke has a dehumidifying capacity of up to 49 litres per day (@30°C/80% RH). Capacities in Condair’s wider condensing dehumidifier range from 49 to 930 litres per day with airflows of up to 8,000m³/h. They can provide dry air directly to a room or be connected to a building’s ducted ventilation system. Models are also available with an external condenser that can expel the heat generated during the drying process remotely and therefore manage temperature control as well as humidity.Winsford’s fire training centre offers the most up-to-date technology to ensure the best possible training for existing firefighters and new recruits, serving a large area of the North West Fire Services. After training the firefighters return to their allocated bases from where they operate a shift system of nine firefighters and officers crewing a fire engine, major rescue unit and incident response unit 24/7. The training centre operates Monday to Friday with high numbers of staff and trainees, and potentially a lot of clothing that needs drying out on a daily basis, so reliability is essential.
Humidification On Ice

Humidification On Ice

Condair Limited

The British Antarctic Survey has recently fitted two Condair resistive steam humidifiers into the sleeping modules of its new Halley VI research station, located on the Brunt Ice Shelf, Antarctica. The extreme Antarctic environment is very dry and so humidification is needed to provide a healthy environment for the scientific team stationed there.The Condair steam humidifiers are helping to suppress electrostatic shocks and reduce drying of the skin, eyes and the mucosa of the nose and mouth. This helps maintain the health of the BAS personnel through reducing the risk of airborne infection.BAS Technical Services confirm the importance of the indoor humidity: “Any Antarctic accommodation structure requires careful environmental and humidification management. The Halley VI station ventilation systems are designed to blend fresh air, as low as -54°C, and recirculated air, which is then humidified and dispersed to inhabited areas.”The Condair resistive steam humidifiers, which use snow meltwater as their water source, were specifically selected for their proven operation in the Antarctic. Condair water level sensors work well with this type of water, a feature not shared by all steam humidifiers. BAS Technical confirmed: “The units are very successful in operation, and are deployed in this and other BAS facilities”. Reliability and continuity were important factors in choosing Condair.The architecturally and technically remarkable Halley VI station consists of a series of interconnecting research and living areas, each module being mounted on height adjustable stilts which terminate in skis. This construction avoids the risk of being buried and crushed under the weight of accumulating snow and, uniquely, means it can be towed and relocated, to avoid being lost as the ever-moving ice shelf breaks up into the Weddell Sea.For over 60 years, the British Antarctic Survey has been the UK’s primary environmental and scientific research organisation in Antarctica. The Halley facility is dedicated to the study of the Earth’s atmosphere and measurements from Halley led to the discovery of the ozone hole in 1985.The station works throughout the year, with a summer team from December to early March of scientific and support staff of up to 70 people. During the long winter, however, which includes being completely cut off for the 105 days of perpetual darkness, the team reduces to just 16 who, including an H&V engineer, maintain the station and keep its scientific projects running.Condair resistive humidifiers deliver high performance, low-maintenance and hygienic steam using a wide range of water qualities. Features such as the user-friendly scale management system mean that these systems have a long and successful history all around the world, for personal comfort and health, in heritage sites and art galleries, and in process humidification.
Humidifier makes fish factory $1M per year

Humidifier makes fish factory $1M per year

Condair Limited

Condair’s JetSpray humidifier is helping refrigeration equipment specialists ICS Cool Energy increase profits at a leading worldwide brand of canned fish by $1 million per year. By maintaining a high humidity around the fish after steaming, evaporative weight loss from the cooked fish has been reduced from approximately 5% to 0.67%. The humidification system is preventing up to 8.5 tonnes of product from simply evaporating each day between cooking and canning.After steaming, the fish needs to be rapidly cooled in order to be processed and canned but can lose up to 20% of its moisture in the process, impacting significantly on its weight. As the factory processes up to 200 tonnes of fish each day, this severely reduced the yield on its product. ICS Cool Energy was tasked by its long standing client to find a more cost effective replacement to its existing cool room sprinkler system, which was proving inefficient in terms of energy and water usage.Malcolm Edwards, Group Technical Manager for ICS Cool Energy, explained what he did next: “ICS installed a chilled water system to provide cooling but we needed advice on the most appropriate humidifier and contacted Condair regarding its JetSpray.“The high skill level of the Condair project management team and its extensive experience in this application gave me confidence to place an order. The support and training Condair subsequently provided was excellent throughout the system development, installation and commissioning. The JetSpray has been in operation now for a number of months keeping the humidity well over the required 90%RH and maintaining a very low 0.67% weight loss. The energy and water savings are a bonus and economies will also be achieved through its easy maintenance programme. All in all, our client could not be happier, and neither could we.”The humidifier combines compressed air and water in precision engineered nozzles to produce a very fine spray that’s rapidly absorbed by the air. This makes it ideal for use in cold stores where the ambient humidity is often high and humidification less readily absorbed by the atmosphere. The line of nozzles is positioned in front of the evaporator coils of the refrigeration system and introduces moisture to the airstream as it enters the cold store.The system’s extremely hygienic design also makes it ideal for food processing facilities. The humidifier incorporates regular automatic flush and purge cycles to ensure that water cannot remain in the system to stagnate. The JetSpray can operate any potable water or demineralised supply and incorporate UV sterlisation or silver ion water treatment.The nozzles have a self-cleaning mechanism, which consists of a pin that pushes through the nozzle orifice whenever the spray stops. This prevents blockages in the nozzle and ensures the system operates robustly in industrial environments with very little required maintenance.
Humidifier reduces carcass weight loss

Humidifier reduces carcass weight loss

Condair Limited

Condair’s JetSpray humidifier is helping abattoir equipment specialists, GM Steel, reduce carcass moisture loss after slaughter by up to 1.5%. By maintaining a consistently high humidity in the chill down area, GM Steel has been able to reduce the moisture loss of a carcass from around 2.5% to less than 1%.For an abattoir processing 3,500 carcasses per week and an average cost of beef at $4/kg, this technology could increase profits by over $2M per year by preventing over 500,000kg of beef simply evaporating into its chill store’s atmosphere.Robert Ten Cate, consultant at GM Steel, explains the process, “A carcass coming from the slaughter line is wet and warm. When it is introduced to the chill store, the cold dry air strips moisture from its exposed surface. The amount depends on the abattoir’s cooling technology but it can be anywhere between 1.2-2.5% of its total weight, and sometimes even more. By maintaining a high humidity in the chill store with a JetSpray humidifier during the initial cooling, moisture loss from the carcass is inhibited and can be reduced to less than 1%.“Independent testing has shown that by maintaining the optimum humidity during cooling, carcass weight loss is reduced without any condensation forming inside the chill store or on the meat. Humidification of the air does not introduce moisture to the surface of the carcass or increase microbial growth.Robert continues, “In fact, client tests showed that the high humidity actually reduced microbial growth rather than promote it. The higher humidity improved the conductivity of the air and consequently increased heat transfer from the carcass. Some installations have seen a significant reduction of their chill cycle to reach the required carcass core temperature. As the carcass temperature is reduced more rapidly the microbial growth is inhibited.“Another significant benefit of a quicker cooling cycle is the reduction in energy consumption of the cooling system. Clients have seen energy bills reduced by as much as 10% when maintaining an optimum humidity in the chill down area due to improved heat transfer efficiency from the carcasses.” Robert concludes.The JetSpray humidifier consists of rows of precision engineered nozzles that combine compressed air and water to produce a spray that has a droplet size of just 7.5microns. The nozzle line is mounted directly in front of the evaporator coils of the refrigeration system and introduces moisture to the airstream as it enters the chill store.The extremely fine spray ensures the moisture is absorbed by the atmosphere and prevents wetting inside the room. The flow of compressed air also avoids the possibility of drips. Tiny needles inside the nozzles act as a self-cleaning mechanism and prevent blockages making the system extremely robust, requiring very little maintenance.The JetSpray humidifier has been developed with hygiene as a principal design factor making it ideal for use in food processing facilities. A reverse osmosis water filter removes all minerals from the supply water before it is treated with ultraviolet sterilization to kill any remaining microorganisms. In addition, the system will regularly run purge and flush cycles to ensure water cannot remain in the humidifier to stagnate.
Humidifiers enhance fermentation at Bajrang Tea

Humidifiers enhance fermentation at Bajrang Tea

Condair Limited

JetSpray humidifiers from Condair are maintaining an optimum 95% relative humidity (%RH) above the continuous fermentation machines at Bajrang Tea factory in West Bengal, maximising the quality of the tea produced there. The improved humidity control has resulted in enhanced fermentation of the tea with better infusion and liquor, and ultimately a higher market value.Before the humidification system was installed by Regent Humidification, Condair’s representative in India, Bajrang Tea was maintaining around 74%RH in the fermentation area. The previous humidification system was failing to provide the high level of humidity required in the area, resulting in the tea losing 10% of its weight from moisture loss during fermentation. As the leaf’s internal moisture content is the catalyst for oxidation, and therefore vital for successful fermentation, any loss in the tea’s moisture level will impact on the quality of the final tea.Aditya Agarwal, Director of Darshananand Holdings Pvt Ltd, the company that owns Bajrang Tea Factory, commented, “We constantly monitor and record the humidity levels in our fermentation area as we know how vital it is for our production quality. Before we had the JetSpray humidifier, we were unable to achieve the high humidity levels we needed. Our previous humidification system also tended to cause wet patches on the floor nearby. However, since we had the JetSpray humidifier installed, the area is consistently at 95%RH and we’ve managed to virtually eliminate weight loss from the tea during fermentation.“This means the moisture stays in the leaf, improving the tea’s fermentation and enhancing the quality of our finished product. We’ve found the JetSpray humidifier very easy to operate and the use of compressed air in the aerosol ensures we never get any drips from the nozzles or wetting on the floor. We are very happy with the system and the service provided by Regent Humidification and Condair.”The humidification system installed at Bajrang Tea is capable of providing up to 187 litres of moisture per hour to the atmosphere. Rows of precision engineered nozzles are located in the ceiling space above the CFM machines and combine compressed air and water to produce the finest sprays that rapidly evaporate.As many nozzles are located throughout the area, the optimum humidity is achieved evenly across the room. This is unlike spinning disc humidifiers or other types of “spot” humidification systems that provide a large quantity of moisture from a central point and rely on air movement to disperse it.As fermentation areas are typically experiencing around 15 air exchanges per hour, the room needs an extremely high humidification output to successfully maintain 95-98%RH, which is the ideal condition for tea fermentation. A single JetSpray system can deliver up to 600 litres per hour making it ideal for use in these areas. The humidifier incorporates automated flush and drain cycles, which prevent water from remaining in the system to stagnate and ensure hygienic operation.
Humidity Equals Productivity at VMT Spinning

Humidity Equals Productivity at VMT Spinning

Condair Limited

VMT Spinning Company has recently installed a JetSpray humidification system from Condair in its post winding section, at its state-of-the-art cotton production facility in Baddi, India, to maintain yarn quality and strength. The JetSpray humidifier was supplied and installed by Condair’s Indian representative, Regent Machine and Servicing, and is capable of delivering around 250 litres of moisture per hour to maintain the ideal air humidity.VMT is part of the well-known Vardhman Group and maintains the highest production standards at its Baddi factory to meet the demanding needs of its mainly Japanese and European customers.Gurpreet Singh, Unit Head at VMT, comments, “The JetSpray has proved highly suitable for our requirements. It consistently maintains the required relative humidity in the area and has very hygienic operation. It is a sealed system with no circulation of water, so there is no scope for growth of micro-organisms. It is also user friendly and practically maintenance-free.Mr Singh continues, “The humidifier is also excellent as an in-room top up system to supplement existing air washers fitted in air handling units. During the hot, dry summer season, the humidifier further benefits us by reducing the temperature in the area, creating a more pleasant and productive environment for staff.”The JetSpray humidifier consists of rows of stainless steel nozzles, mounted high in the area to be humidified, which combine compressed air and water to produce very fine aerosols. The use of compressed air atomises the water so it evaporates very rapidly and guarantees drip-free humidification. As moisture is introduced across an area from many points of injection, the humidity level is very consistent and evenly spread throughout the room. This helps avoid high and low levels that some singular spot humidifiers can cause in a production area.Automatic flush and drain cycles ensure water cannot remain in the system to stagnate and combats microbial growth. Optional UV sterilisation or silver ion dosing offer additional hygiene safeguards for total peace-of-mind.The JetSpray humidifier uses standard plumbing fittings so is easy to install in busy industrial environments and the nozzles have a self-cleaning mechanism that minimises maintenance. A tiny pin pushes through the nozzle’s spray orifice whenever the system stops operating to prevent blockages affecting performance. The innovative design makes the nozzles so robust in operation that they carry a 10-year warranty.VMT Spinning Company at Baddi was formed in 1993 when Vardhman entered into a joint venture with M/S Marubeni Corporation and Toho Rayon Co Ltd of Japan.
Humidity Keeps the Spiders Happy at ZSL London Zoo

Humidity Keeps the Spiders Happy at ZSL London Zoo

Condair Limited

Condair has supplied a Condair CP3 Mini steam humidifier for the “spider nursery” at ZSL London Zoo. The compact wall-mounted humidifier provides up to 4kg of steam per hour to the atmosphere, with its built-in fan unit. This is sufficient to maintain the ideal air humidity of 70%RH, as the arachnids would have enjoyed in their indigenous habitats from around the world.Dave Clarke, ZSL’s Head of Invertebrates, comments, “Most of our spider species come from tropical forest, where the humidity is naturally high. If the atmosphere is too dry in their holding area, they would be unhealthy, unlikely to breed, and have particular difficulty in moulting their exoskeletons.”“Our spiders include the cosmotropical Huntsman spider, Mexican red-kneed spider (one of the large bird-eating, or so-called “tarantula” spiders), rare Desertas wolf spiders and Peacock Parachute spiders. The latter two are part of European Breeding Programmes, so the humidification system is playing an important role in helping us protect these threatened species.” Dave continues.“Having worked with Condair since 2008, we now rely on their steam humidifiers, which we find both efficient and easy to use. They are particularly important for our irreplaceable populations of endangered species, for example our Polynesian tree snails, many of which are now sadly extinct in the wild.” Dave concludes.The Condair CP3 Mini is ideal for small areas such as London Zoo’s spider nursery, due to its built-in fan unit and user-friendly design. The humidifier has a discrete fan incorporated into the top of its cabinet to disperse the steam into a room. This makes the humidifier very compact and is unlike most other humidifiers of its type, which are supplied with an additional bolt-on fan unit element.The CP3 Mini installed at the Spider Nursery has exposed drain and electrical connections, but it can be installed with rear entering services, to avoid visible pipes and cables. This makes the system ideal for public areas or offices, which want an attractive and discrete humidity control solution.ZSL London Zoo is the world’s oldest scientific zoo, having been formed in 1828 for scientific study and then opened to the public in 1847. The zoo has the UK’s first ever walk-through spider exhibit, where visitors can even pose for a pic with golden orb spiders, in their one metre webs, with the help of a “Spider Selfie” mirror. The zoo also operates a very successful arachnophobia curing programme, where spider-haters can be turned into spider-lovers, leaving the zoo with a new-found appreciation for arachnids.
Humidity Matters at Jersey Air Traffic Control

Humidity Matters at Jersey Air Traffic Control

Condair Limited

Jersey Air Traffic Control has recently installed four Condair steam humidifiers at its centre in Jersey Airport, which is responsible for the coordination of air traffic in the busy skies above the Channel Islands. Air traffic control is a demanding role, with aircraft and passenger safety its primary goal, and the humidifiers help provide a comfortable and productive environment for air traffic controllers and engineering staff by combatting the visual discomfort created by dry air.The Channel Islands are popular destinations for commercial airlines and private aircraft pilots alike, and high volumes of air traffic pass through its air space. In 2014, there were over 100,000 aircraft departures and arrivals at the three airports of Jersey, Guernsey and Alderney, and almost 2.5M travellers passed in and out of them. The Condair humidifiers serve the iconic Control Tower, which controls the flight arrivals and departures from Jersey Airport itself, and areas in the air Traffic Control Centre, both of which were built in 2010 to accommodate the increasing attraction of flying to and from the islands.Air traffic control in the Channel Islands is a highly responsible role. It has a high visual and mental workload, using purpose-designed interactive screens as essential tools, frequent interaction with aircrew and important decisions being made. Shift work, early starts and late finishes can also have an effect. Les Smallwood, Senior Air Traffic Control Officer at the centre, explains, “The human element is important. In a job where errors could be critical, an environment that is comfortable and considers people’s well-being also supports their working needs. The humidifiers are a part of this.”The need for humidification first became apparent amongst staff wearing contact lenses. Les Smallwood continues, “We use air conditioning to maintain an environment of 21°C but this was drying the air. People’s eyes were becoming uncomfortable, especially for those wearing contact lenses. We used mobile humidifiers at first, to prove the point, before investing in a permanent solution with the Condair humidifiers”. Les confirms that air traffic control staff and the airport’s building services team are pleased with the results.The largest capacity humidifier, a 30kg/h resistive steam humidifier, supplies the air handling system for the first floor of the Air Traffic Control Centre, which includes air traffic control offices and rest areas, to maintain around 50%RH. Three Condair CP3 Mini in-room humidifiers are used to do the same in the Control Tower itself and in the Air Traffic Engineering offices, whose staff are responsible for the good operation of radar, navaids, electronic equipment and associated services.Condair resistive steam humidifiers feature a unique scale collection tank for easy and straightforward maintenance. The Condair CP3 Mini units are compact and discreetly-designed electrode boiler humidifiers, wall-mounted in the areas concerned to deliver up to 4kg/h of pure steam directly into the space. Routine maintenance is quick and kept simple by the easily exchanged boiling cylinders.Jersey Health and Safety Inspectorate’s Display Screen Equipment at Work ACoP, confirms the importance of maintaining of a level of relative humidity that is adequate to prevent the discomfort and sore eyes that are characteristically associated with dry air, as part of an ergonomically-optimised working environment. This echoes the same guidance given in the UK Health & Safety Executive’s DSE ACoP and other European directives.Dry air can be caused by air conditioning and also arises during cooler winter months when indoor relative humidity drops as it is heated. Even in a mild and agreeable climate like Jersey’s, it can be a particular problem for computer screen users, as the air around a screen can be drier and more prone to electrostatic effects than its surroundings, due to the increased temperature locally. Humidifiers effectively address these issues.Maintaining a relative humidity of 40-60% has also been shown to reduce susceptibility to infection by preventing the drying of the moist lining of the mouth, throat and nose, and airborne viruses have been shown to survive for a shorter time at this level. Conveniently, the level of relative humidity that suits people’s health also provides the ideal environment for IT systems and electronic equipment.
JetSpray at Aston Martin

JetSpray at Aston Martin

Condair Limited

Condair has installed JetSpray humidification systems into the finishing areas at Aston Martin’s Newport Pagnell and Bloxham plants. By maintaining a level of humidity at 55%RH, any dust that is in the atmosphere around the cars is suppressed, giving a much finer finish during the painting and sanding processes. The evaporating water also produces a powerful cooling effect on the air, which benefits the workers and reduces air conditioning costs.The JetSpray system consists of a series of atomising nozzles that produce fine sprays of moisture directly into the air. The sprays have an average droplet size of just 7.5m and instantly evaporate, raising the humidity. A self-cleaning mechanism ensures that the nozzles can’t become blocked and need very little maintenance. With no drips or droplets, no requirement to heat the water, and therefore very low running costs, the JetSpray system is ideal for busy industrial environments and can be used with mains, demineralised or softened water.Aston Martin has grown over the last 80 years to become a world-renowned manufacturer of the finest, exclusive, luxury sports cars. The Newport Pagnell plant is its traditional base manufacturing the flagship model - The Vanquish V12 - with its 460bhp, 6 litre, 48 valve and V12 engine. The newer Bloxham plant produces the superb DB7 Vantage Volante and Coupé.The JetSpray system installed at the Newport Pagnell plant consisted of 24 nozzles releasing 108 litres of water into the atmosphere around the cars every hour. The installation at Bloxham was even larger, with a total of 68 nozzles pumping out 250 litres of water per hour.Alan Darrock at Aston Martin, comments, “We need a reliable, effective humidification system to ensure that we can achieve the utmost finish to our cars. Since the new equipment was installed we have seen improvement in the quality of the paint finish, and our workforce now keep the doors closed. We have been more than pleased with the service and skill that Condair offers and will be using them in other production areas.”
Printing perfection with JetSpray

Printing perfection with JetSpray

Condair Limited

When John Watson & Co, the oldest printing company in Scotland, was seeking to enhance its process control by improving the humidity of its print room, it contacted Condair, who specified and installed the JetSpray air and water atomising humidifier, developed especially for the printing industry.Paper is a hygroscopic material that is very susceptible to changes in relative humidity (RH). For optimum printing and paper storage conditions, the humidity should be kept between 40-60%RH. The heat generated by print machinery and heaters in enclosed conditions can cause the air to dry and, subsequently, the paper. In winter, RH can fall as low as 15-20%RH resulting in a build-up of static and printing issues such as misregister, web breaks, paper curl and paper cracking when folded. By humidifying the atmosphere around printing presses, reel-stand areas and paper stores, problems like these can be dramatically reduced.Chris Fyfe, Quality Assurance Manager at John Watson, explained how Condair met his company’s needs: “When paper loses moisture, ink will not adhere properly, which could cause a problem for our printing company whose reputation for quality is high. Not only has the JetSpray been proven in our industry, it is also uncomplicated, energy efficient and extremely hygienic in operation. Due to the conditions in our print room, the humidifier has been running 99% of the day since installation, keeping RH at a perfect 50%.”The JetSpray controls humidity to ±2.5%RH and was designed specifically for the printing industry as it needs minimal maintenance, has low running costs and is very hygienic. It consists of a control panel feeding compressed air and water to rows of nozzles. The nozzle design ensures that water can only be introduced when compressed air is flowing through the system, guaranteeing drip-free sprays. The spray released from the nozzles has a tiny droplet size of just 7.5μm, which rapidly evaporates in the air, raising its humidity.A PureFlo Ag+ silver ion dosing system is incorporated on the incoming water supply to combat microbial build-up. Silver is a powerful antibacterial element and provides a strong residual effect throughout the water pipe work. In additional to this, automatic flush and purge cycles prevent water from remaining in the system, further controlling microbial growth and ensuring hygienic operation. These features have helped the JetSpray achieve the independently verified VDI6022 hygiene standard.The atomising humidifier uses 90% less energy than electric steam humidifiers. Not only are there considerable cost savings but, for a system producing 100kg of moisture per hour, this equates to a reduction in CO2 emissions of around 260 tonnes over five years.The JetSpray is very easy to install, can run on mains, demineralised or softened water and due to a self-clean pin in the nozzle, requires little maintenance. The internal components of the JetSpray control panel are easily accessible with all electronic elements being enclosed in a separate compartment above the water pipes.
Steinway in tune with Condair

Steinway in tune with Condair

Condair Limited

Condair’s steam humidifiers are playing a vital role in maintaining the exceptional craftsmanship involved in the production of Steinway’s famous pianos. Steinway & Sons, synonymous with building the world’s best and finest pianos for over 160 years, recently refurbished its impressive London showroom in Marylebone. The company required its contractor to create the optimum environmental conditions to prevent the wood used to craft these precision instruments from warping. Condair’s resistive steam (RS) humidifiers were specified and then installed in three rooms in the building, including the basement where the workshop is situated. All the units are feeding steam into air handling units to maintain the vital humidity levels required.Steinway’s UK managing director, Craig Terry, explains: “Incredibly rare and expensive wood is used in some of our models – but actually any type of wood is susceptible to changes in environmental conditions. Dryness is the enemy of pianos so humidity is really important. We need 40% to 50% humidity all the time to protect the wood, whether they’re in the showroom or the workshop. Condair’s units are ideal for the job. “And because we rely so heavily on the reliability of the humidifiers, we also contracted with Condair to service the humidifiers at regular intervals. Would I recommend Condair? Oh yes, they’ve supplied great service.”If these precision musical instruments, which are worth many thousands of pounds each, are exposed to dry air it can change the instrument’s dimensions very slightly. This would be detrimental to their performance and result in them requiring much more frequent tuning, eventually leading to permanent deterioration over time. Thankfully, Condair’s RS humidifiers provide the perfect protection.The Condair RS humidifiers installed at Steinway are capable of creating up to 16kg/h of humidity but the range has models offering maximum outputs from 5 to 160kg/h. The humidifier delivers accurate control without the expense of plastic disposable boiling cylinders, simplifying maintenance and keeping downtime to a minimum. Scale that forms on the heating elements breaks off under normal operation and falls into the externally located scale collector tank. Scale removal is a simple process of draining the tank with the push of a button, allowing the unit to cool then disconnecting the tank and emptying it.An advanced touchscreen control panel makes operation simple, while providing detailed diagnostic reporting. In addition, a USB connection allows performance data to be downloaded into Excel and the humidifier’s software to be easily updated.Dave Marshall-George, UK Sales Director at Condair, added: “Humidity control for Steinway is of particular importance during winter in the UK. As soon as the weather turns cold, indoor humidity may drop below the required 40%RH. However, air conditioning systems will also dry the air, so the humidification system will have been in regular use. Basically, whenever there’s a requirement to precisely control the environmental conditions around the pianos, the humidifiers will automatically do exactly what’s needed of them.“We really value our relationship with Steinway and appreciate their faith in both the capability of the Condair RS humidifiers and our service engineers, who keep them running in tip top condition.” 
The world's largest evaporative cooling system

The world's largest evaporative cooling system

Condair Limited

Condair has designed, manufactured and supplied a spray evaporative cooling system that conditions the air across a 15-hectare site in the Saudi Arabian city of Medina by up to 10°C.Medina is the second most important pilgrimage site in Islam and is home to one of the largest mosques in the world. Millions of Muslims make an annual pilgrimage to the Saudi city, which is hot and dry all year round.In the sun, the temperature often rises to 50°C. In order to provide visitors to the outdoor site with greater comfort, large umbrellas have been erected to provide protection from the sun. There are a total of 250 sun umbrellas, with each one providing shade for an area of around 600 m².During a visit to the USA, the King of Saudi Arabia saw an outdoor air conditioning system that vaporized water, thereby cooling the air. The King was so enthusiastic about this technology that he wanted to install a similar system under the sun umbrellas in Medina.The supplier of the large umbrellas first attempted to develop a suitable system himself. When this proved unsuccessful, he turned to Condair. Within just a few months the supply contract had been signed. Condair then developed the special parts, including a special pump station that could be integrated into the enormous sun umbrellas. These water pumps are installed at a height of six meters directly below the light fixtures. In addition to the pumps, Condair also supplied the spray elements that are installed on the ventilators and discharge vaporized water.Two of the biggest challenges were the requirement for an extremely low noise level and the limited space available for installing the water pumps.Further challenges included the extremely high ambient temperatures and the exacting hygienic requirements for the system. The entire system is designed for operation in ambient temperatures up to 60 degrees Celsius.As only Muslims can access the prayer site, Condair provided training for the installation mechanics so they themselves could manage both the installation of the pump stations and the necessary hygienic control for the entire system. When all the systems are operating 50,000 litres of water per hour can be vaporized. This results in a pleasant and appreciable drop in temperature of up to 10°C across the site.Once the prototypes had been approved at the end of 2010, all 250 pump stations were manufactured in spring 2011. The installation was completed in August 2011 and since then pilgrims to the site have been enjoying cooler air temperatures thanks to the biggest outdoor evaporative cooling system in the world.

Wellcome Trust Condair HP Humidifier

Wellcome Trust Condair HP Humidifier

Condair Limited

Condair has recently supplied and installed three Condair HP high pressure spray humidification systems at Wellcome Trust’s headquarters in London’s Euston Road. The humidifiers are maintaining the humidity in the building’s atrium for the health, comfort and well-being of staff and visitors.Wellcome Trust is one of the world’s largest independent charitable trusts, providing funding of around £700M annually to support research into improvements in human and animal health, and the medical humanities. The Gibbs Building is the organisation’s impressive HQ, opened by Her Majesty the Queen in 2004.Located in three AHUs in the basement and ninth floor of the building, the new Condair HP humidifiers provide low energy, hygienic humidity by introducing finely atomised sprays of RO water directly into the airstream. These rapidly evaporate to moisten the air and give the desired 50%RH in the atrium. In doing so, staff and visitors to the Gibbs Building experience an environment that is ideal for human comfort, which is in keeping with Wellcome Trust’s own aims. Mark Scally, Building Services Manager at Wellcome Trust, confirms that the Condair HP system “is running well and conditions in the atrium are being maintained”.The installed Condair HP humidifiers release up to 425 litres per hour at 70bar from manifolds of high pressure nozzles. The micro-fine sprays are spread uniformly across the AHU, with multi-step arrays providing close control over output. Water is filtered by reverse osmosis and exposed to UV light, ensuring hygienic operation, and the system regularly flushed to prevent the possibility of stagnation. The entire system is made in stainless steel, including the oil-free high pressure water pumps, which further contribute to low maintenance and hygiene.Condair has a long and successful history with the Wellcome Trust, having supplied the previous spray humidifier back in 2003, during the Gibbs Building’s initial development, which the new Condair HP is now replacing. Using cold water humidification rather than traditional steam humidifiers significantly reduces energy consumption as well as offering the benefit of low cost evaporative cooling to an airstream.Alongside supplying the humidification systems at the Gibbs Building, Condair, in conjunction with Optimum Group Services, also maintains them under a Condair planned maintenance agreement. This ensures the humidifiers operate efficiently and hygienically for their maximum service lifetime and that the highest level of technical knowledge is delivered on-site direct from the manufacturer.The Gibbs Building features impressive works of art in the foyer and a stunning glass and steel sculpture called Bleigiessen, designed by Thomas Heatherwick. It stretches the full height of the atrium and is overlooked by the surrounding walkways of each floor. The adjacent building, which is also humidified by Condair, houses the extraordinary Wellcome Collection, including the Wellcome Library, a unique mix of galleries, exhibitions, events and meeting, reading and eating places, which is open to visitors who are curious to explore connections between medicine, art and culture.The Condair Group is the world’s leading specialist in humidification and evaporative cooling, with energy efficient, hygienic and innovative technologies for commercial, industrial and heritage applications.
