Smoke and heat extraction systems (SHEV systems) are an essential component of preventive fire protection. In the event of a fire, they ensure that toxic smoke gases and hot air are directed out of the building - a life-saving mechanism that secures escape and rescue routes and provides emergency services with better orientation.
What is a SHEV system and how does it work?
A SHEV system detects smoke development at an early stage and automatically opens defined smoke extraction openings in the roof or on the façade. At the same time, fresh air enters the building via air vents. This controlled air flow directs the smoke from the interior to the outside.
Typical components of a SHEV system are
- Release units (e.g. automatic fire detectors or push-button detectors),
- Drives (electric or pneumatic),
- Smoke extraction openings (such as skylight domes, louvre windows or roof flaps),
- control centers and emergency power supply.
Why are SHEV systems so important?
In most fires, the greatest danger is not the fire itself, but the smoke. Just a few breaths can be life-threatening. A functioning SHEV system
- secures escape and rescue routes,
- improves visibility for emergency services,
- minimizes heat build-up and consequential damage,
- supports effective firefighting.
SHEV systems therefore not only save lives, but also protect property and shorten response times.
Where are SHEV systems used?
SHEV systems are prescribed or strongly recommended in numerous building types - for example in:
- educational and care facilities,
- industrial halls, logistics centers and workshops,
- sales and assembly facilities,
- care facilities and hospitals.
The respective design is based on applicable building regulations, special building regulations and individual fire protection concepts.
