These systems save lives and property if there is a fire. Failure to maintain SHEVS is not only an offence, but may render fire insurance invalid. We offer expert maintenance and servicing of smoke & heat exhaust ventilation systems for all buildings.
In case of fire in a room, due to buoyancy the hot and smoky gasses are rising above the fire and spread at high level. Without a smoke and heat ventilation system the entire volume of the room will be smoke logged within minutes. The smoke and heat ventilation systems (called further SHEVS) will make sure that a smoke free zone will be maintained at low level by extracting an amount of smoky gases out of the smoke compartment. The SHEVS are also used to extract the heat from a starting fire, it will help keeping the evacuation routes free of smoke and by doing so will help the evacuation of people from a building in fire and simultaneously reduce the damage directly due to the fire and the financial losses, reduce the smoke damage, allow the repression by the Fire Brigade by improving the visibility, reduce the temperature under the roof and reduce the horizontal spread of the fire.
The objective of this guideline is a tool to plan and design SHEVS without the aim of computer simulation for the following utilisation:
Industry, production and storage buildings
Rooms with high number of people
