Smoke and Heat Extraction Systems

Like the fire alarm system, the smoke and heat extraction system is also one of the holistic fire protection solutions for your building. In special buildings, smoke and heat extraction systems are required by law under building regulations.

As a rule, the type and size of smoke and heat extraction system that’s needed is described in the fire protection concept. Smoke and heat extraction systems are planned in accordance with DIN 18232.

We’ll be happy to assist you in planning and implementing your smoke and heat extraction system.

There are different types of smoke and heat extraction systems

Natural smoke extraction systems: thermal rising principle, without mechanical support.
Mechanical smoke extraction systems: smoke and heat extraction with motorised drive (e.g. flue gas fans).
Smoke differential pressure systems: positive pressure is used to keep a stairwell free of smoke, for example.
Lift shaft smoke extraction (e.g. fire department lifts).
Garage smoke extraction.
Heat extraction.

Natural smoke and heat extraction systems can be controlled pneumatically or electrically.

All smoke and heat extraction systems pursue protection goals

All smoke and heat extraction systems have the following protection goals:

To enable people to rescue themselves by being able to see and breathe.
To facilitate the rescue of others by enabling rescue forces to see and better orientate themselves.
To protect property or assets that are important to the company by preventing smoke from reaching the unaffected sections of the building.
To prevent disruptions to operations by supporting firefighting efforts and preventing smoke from spreading further.

It’s well known that when there’s a fire in a building, it isn’t the fire that is the most dangerous, but the fumes or smoke that are thereby produced. Depending on what is burning in a utilisation unit (fire load), different combustion gases are produced, which can on the one hand be corrosive to the skin and, on the other, can cause life-threatening injuries to the respiratory tract. The main product of combustion is usually carbon monoxide (CO). Three to four long breaths of CO are enough to reduce the chances of survival to almost zero. It is thus all the more important that smoke gases are quickly extracted from escape routes.
