Smoke and Heat Ventilation

Generally speaking, our fire security systems serve three main purposes: escape route security, the support of fire service containment measures and the protection of the structure of the building from excessive temperatures.

The greatest hazard in the event of fire is the accumulation of smoke and heat. Smoke diminishes visibility, obscures the escape routes and makes the fire fighters’ job even more difficult. It is therefore of paramount importance that the breakout of fire is detected as swiftly as possible to prevent the further spread of smoke. Our smoke & heat extraction systems have one essential function: to reduce the risks to people and materials by means of speedy extraction of smoke and heat.

Natural Ventilation

Natural ventilation is an affordable, effective, silent and environmentally friendly technique, base on one simple principle: the fact that warm air rises. Many problems can therefore be solved by installing a natural ventilation system on the roof or in the upper wall.

Air inlet

Sufficient air supply is indispensable for both natural and mechanical fire and continuous ventilation systems.

In the case of natural extraction of hot air and / or smoke through grilles installed in the roof of a building, the thermal effect automatically draw in fresh air through vents installed lower down (in the wall).

In the case of mechanical extraction, however, the system provides forced circulation of the necessary air supply.

In both natural an mechanical ventilation systems, insufficient air supply would significantly hamper the effectiveness of the system, while in the case of a smoke & heat extraction system it may even prove hazardous. The necessary air supply capacity should therefore always be calculated in accordance with the current calculation methods and regulations.

Brakel offers a vast range of natural supply fans, which ensure the appropriate air supply for either a smoke & heat extraction / ventilation system or continuous ventilation system (or even a combination of the two).
