Waitrose Distribution: Roma-3 mild steel grating fence in a galvanized finish was specified for the boundary demarcation.

Lang+Fulton

Waitrose’s Distribution Centre at Bracknell delivers to more than 60 stores, handling up to 150,000 cases of chilled products. The new warehouse was conceived to a ‘green’ design; generating 20% of renewable energy on site with waste heat and office cooling recycled from the refrigeration process, efficient lighting and low carbon emissions. Hoardings during construction were made from recycled plastic and materials from the demolition were also recycled. In keeping with the concept of sourcing natural materials, a Roma-3 mild steel grating fence in a galvanized finish was specified for the boundary demarcation.
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.
JS Air Curtains at Reynolds Furniture

JS Air Curtains at Reynolds Furniture

JS Air Curtains

As part of a major refurbishment at its retail store in Bognor Regis, Reynolds Furniture selected JS Air Curtains’ Finesse and Optima air curtains to maintain the internal atmosphere while complementing its modern interior design. Discretely blending in with their surroundings, the air curtains are ensuring customer and staff comfort throughout the summer and winter.A family-run business since 1867, Reynolds is the largest furniture store in Sussex and prides itself on excellent customer service. Needing to bring its 25,000sq ft of retail space up-to-date and enhance its customers’ buying experience, it commissioned air conditioning specialist, South Coast Refrigeration Services, to install a new cooling and heating system. As part of this installation, air curtains on the ground floor were an essential ingredient to maintain the ambient temperature; keeping the cool conditioned air in during the summer and the cold air out during the winter.Brian Ritchie from South Coast Refrigeration project managed the installation: “Having previously enjoyed a problem-free relationship with JS Air Curtains, we turned again to this local supplier. We knew we could rely on the performance of the air curtains and that this kit would be easy to install unobtrusively at both entrance points.”A 1m Finesse concealed air curtain was installed flush with the ceiling over the back door, whilst a 2m Mini Optima was suspended above the automatic sliding doors at the main customer entrance.Matthew Reynolds, finance director at Reynolds, commented: “The renovation of our furniture store was designed to create a modern environment where our customers would feel comfortable and at ease making their buying decisions. It was important that the air curtains looked great, to match the aesthetics of our décor, as well as maintaining the ambient temperature. We have been very pleased with the result and the air curtains have performed well so far, keeping our customers cool over the hot summer. We are confident they will continue to do their job through the colder months to come.”The Finesse concealed air curtain for suspended ceilings is suitable for ceiling voids of just 350mm. It is simple to install and has easy access for maintenance. It is available in 0.5m lengths from 1m to 2m with non-heated, electric or hot water heated models and has a comprehensive range of control options.The Mini Optima air curtain is an economic solution also available in lengths up to 2m. It is available in single or three phase power options with maximum airflows of 1,350m³/hr making it ideal for protecting doorways up to 2.2m high.
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.
Air Curtains Seal Natures Way Foods’ Chill Store

Air Curtains Seal Natures Way Foods’ Chill Store

JS Air Curtains

JS Air Curtains recently sealed the doorway of a salad store at Natures Way Foods in Chichester with a chill store air curtain. The units help maintain the required 2°C temperature inside the cold store by creating a curtain of ambient air over the opening, keeping the chilled air inside, whilst providing unhindered access and visibility for the forklifts.The company previously used fast acting electric doors with plastic slat curtains but with the doors open the temperature near the doorway was rising to 8°C. In addition, the plastic curtains quickly became dirty and scratched and obstructed the vision of the forklift drivers.Sean Burns, Services Manager at Natures Way Foods commented, “We were using electric doors but wanted to have better access and visibility for the forklifts. We also had heat spots near the door and were getting about 8°C with the door open. However, without the door and with the air curtains installed we are now maintaining 2°C, even right next to the doorway in the summer.“Since seeing how effective the air curtains are at sealing the entrance, I’ve ordered two more for a chill store at our Passion Food Café facility in Portsmouth.”By installing air curtains on chill store doorways energy efficiency is also improved. Fridges and freezers waste a great deal of energy every time the doors open. Warm air flows in and refrigerated air flows out. By having a curtain of ambient air blasted down across the doorway the cold air is not allowed to escape ensuring temperature and humidity remain consistent.Natures Way Foods prepares over 12 billion salad leaves per year and supplies salads and prepared vegetables to clients that include Tescos, MacDonalds, Pizza Express and Morrisons.
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.
24 St James Square, London

24 St James Square, London

AET Flexible Space

AET Flexible Space was specified to supply its innovative CAM-V underfloor air conditioning (UfAC) system for the refurbishment of 24 St James’s Square, completed in early 2020. The design brief was to maximise floor-to-ceiling heights and enhance the double aspect interior. One of the key challenges was the need to preserve key architectural features, whilst at the same time providing, flexible, modern, premium office space. These needs could not have been met using a conventional overhead system, which would have taken up valuable headroom and created awkward junctions where window heads met suspended ceiling grids or exposed services. Using an underfloor air conditioning system enabled the architects, BLDA, to eliminate ceiling-based services allowing for a plasterboard ceiling to be installed tight against the soffit and down stand beams. Thanks to the AET system, key architectural elements of the building were preserved, as well as increasing natural light levels and enhancing the striking double-aspect interior. “The AET downflow units promptly stood out as the obvious candidate for several reasons, including having the absolute minimum requirement for floor void height, and offering excellent distribution of cooling, heating and ventilation evenly across the whole floor whilst reducing energy consumption.” – M&E Consultant, Vic Holloway (Edward Pearce LLP). AET’s UfAC system’s make use of the space beneath a raised access floor to create a ventilation path, eliminating the need for ceiling-based mechanical services helping to maximising the floor to ceiling heights creating a brighter and more and airy office environment. A mix of CAM-V22 & 33 units were installed across the eight floors of office space. Roof mounted high efficiency heat pump units serve the refrigerant coils in each CAM’s. Conditioned air is delivered into the space via AET’s market leading TU350 slimline Fantile™ units which sit 160mm within the floor void. To avoid unwanted grilles at high-level AET designed bespoke floor extract grilles that look identical to a Fantile™ units, to allow room air to be extracted directly from the floor void enabling the interior aesthetic to remain consistent and simplify duct routes within the buildings core. Common complaints from staff, prior to the refurbishment, were variations in temperature across the office space, high level cold draughts and a lack of natural daylight light. An UfAC solution however, provides greater individual control of localised temperature, unobtrusive movement of air and makes for a more comfortable, brighter working environment. The 24 St James’s Square project has already won the “Best Office Architecture London” award at the 2019 International Property Awards and has now very recently been awarded ‘Retrofit Project of the Year’ at the H&V News Awards 2020. The building is being let as Grade A office space by BNP Paribas Real Estate who advised the developer, Misland Capital, to consider AET’s system’s based on their positive experience with 28 Saville Row which AET completed in 2014.
