Smoke ventilation system

NSHEVS – 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.
