NSHEVs
Natural Smoke and Heat Exhaust Ventilators (NSHEVs) are usually installed on buildings like schools, universities, theatres, shopping malls, accommodation facilities and industrial plants. Moreover, many countries in the European Community require NSHEVs to be mandatorily installed also on private buildings on stairwells and/or lift shafts.
This product is vitally important since in the event of a fire a NSHEV enables smoke and hot gases to come out of the building. The higher the smoke plume goes, the more the visual field increases, allowing rescuers to intervene saving people and goods.
