Elevator shaft smoke and heat extraction system

These energy-efficient exhaust air openings for lift shafts only open in the event of a fire, otherwise they are closed so that no energy is wasted.

Lift shaft smoke extraction system - consulting, installation & maintenance

The elevator shaft smoke and heat extraction system serves as an exhaust air opening in the elevator shaft so that fire gases and smoke can escape in the event of a fire.

This way, they replace permanent openings in the shaft head, which were installed in the past for smoke extraction from elevator shafts. These permanent openings resulted in a high loss of thermal energy. Consequently, elevator shaft smoke and heat extraction systems are used primarily in buildings where energy efficiency and safety are of great importance. In addition, the German Energy Saving Ordinance (EnEV) increasingly requires permanent openings to be closed. As a result, to protect people from toxic smoke gases in the event of a fire, smoke and heat extraction systems are required.

The basis of a smoke and heat extraction system is an technical system that controls the exhaust air opening via a central control unit with integrated backup power supply. In case of fire, this is triggered manually by a release button close to the landing door or automatically by a smoke aspiration system or point-type smoke detectors. The responsible fire protection authority regulates the respective design.

An elevator shaft smoke and heat extraction system requires annual maintenance by a competent person, such as the specialist staff of CWS Fire Safety.

We also offer a complete package for your elevator shaft smoke and heat extraction system, meaning that we take over the analysis of the local conditions as well as the planning and installation of the system. All systems offered are certified and approved. Furthermore, we carry out regular maintenance, e.g. automatically via a maintenance contract.

Advantages

  • Increased burglary resistance compared to a permanent opening
  • Daily or automatic elevator shaft ventilation possible by time settings or wind and rain control

Sustainability

Elevator shaft smoke and heat extraction systems prevent loss of thermal energy in everyday life.
