A building is on fire. People are running around. First and foremost it is a matter of saving lives and preventing material damage. To achieve this, smoke and heat exhaust ventilators (SHEV) are a vital part of the standards safety equipment in a fire-protection system. Efficient smoke and heat ventilation keeps the escape routes clear and major damage can be prevented.

Smoke and fire gases are responsible for approx. 90% of the victims. Furthermore, in many cases smoke and fire gases cause serious material damage. The use of smoke and heat ventilation systems reduces the concentration of developing smoke and fire gases and extracts them efficiently from the building. The danger is reduced to a minimum before the smoke spreads in the building and makes escape routes impassable.

Safety is one of mankind’s elementary basic needs - no matter where we live or what life situation we find ourselves in. The most important factors when designing a smoke ventilation system are that it functions reliably and activates rapidly. As a result, people can be safety evacuated and lives can be saved.

                                 

It must always work quickly and effectively

D+H technology immediately detects any smoke developing by means of a smoke alarm. The vents for the ventilation are then opened in the shortest of times by an electric motor. In order to generate the corresponding air draught, the fresh air vents in the lower areas of a building must be opened at the same time. Smoke, gases and heat are chanelled directly into the open air by the thermal lift, thus ensuring that evacuation and escape routes remain low-smoke areas. As a specialist in the field of smoke and heat ventilation, D+H offers a comprehensive range of components and systems.
