Smoke and Heat Exhaust Ventilation System
Natural smoke and heat exhaust ventilation systems
Smoke and heat exhaust ventilation systems are used to ensure that, in the event of fire, there is a smoke-free area as an escape zone. They achieve this by eliminating a sufficient amount of the flue gas. In accordance with the current European standard EN 12101-2, NSHEVS are regarded as a unit comprising an opening element and an electric motor, with these two components being tested and approved as a whole. WICONA NSHEVS are manufactured on the basis of the standard window systems and offer extensive freedom of design for use in façades and roofs.
