7 things you need to know about Coxdome Firejet JetCox SHEV Unit Smoke Vent

Trade Access Panels

AOV or Automatic Opening Vent systems control the airflow of smoke in a fire. According to EN12102-2 it is a statutory requirement to have an AOV unit on a new construction. Since 2006, Europe has required that the AOVs meet with the standards set forth in DIN EN12102-2. As a result, many companies have made their versions of AOVs. Majority of these options only go as far as barely meeting the before stated regulations. However, the Coxdome Firejet SHEV exceeds the expectations and requirements of a standard AOV.

Cast Iron Rainwater and Drain Outlet Cowl

Cast Iron Rainwater and Drain Outlet Cowl

Cast Iron Air Brick Company

Before there was an open, 4" (100mm) diameter pipe that drained water from the back of this Devon farm house into the yard. Apart from an open pipe, which never looks good on a listed building, when it rained heavily there was water gushing out across the road causing havoc to any cars parked nearby. With the installation of the cast iron cowled conservation vent now the water is deflected downwards and the opening is no longer open to the elements and in eye line. With a choice of 100mm or 125mm spigots this cowled vent has many uses

Mechanical smoke ventilation at Local Blackfriars

Dyer Environmental Controls Ltd

Local Blackfriars is a gated community in Salford, providing 380 apartments. A unique aspect of the residential scheme is the Grade II listed Black Friar pub merged into the development.Dyer were asked to supply and install mechanical smoke ventilation systems for the apartment blocks and the underground car parks. Dyer worked closely with Fire Design Solutions and Domis Construction over the course of the project to provide a successful outcome.When a floor goes into fire, the dampers in both shafts on the affected floor open. The chain drive on the AOV window on the affected floor opens to provide fresh inlet air. The vent at the head of the stairwell will also open. Both sets of fans work to extract the smoke and poisonous gases.On activation of a thermostat on a single floor, both the dampers on the affected floor will open. One set of fans will extract on trickle mode and the other shaft will provide fresh inlet air for the system. The vent at the head of the stair will also partly open.If the rain sensor is activated this will override and close the roof vent.If more than one thermostat operates, the dampers on the affected floors will open and be balanced to provide an equal air flow on each floor.Smoke detection in any zone will override the natural ventilation system and smoke extract will take priority.Dyer provided an eco-park® mechanical ventilation system. Advanced components and control systems allows for efficient energy usage.
