NSHEV Free Smoke is a patented and compact system consisting of an aluminum frame with a sealing gasket.
Aluminum hinges, galvanized steel rivets and fittings, and an opening device with a three-stage pneumatic cylinder operating with a mixed gas of CO2/OIL, pivotally mounted between two parallel brackets.
It also includes a CO2 cylinder, a thermal fuse vial (with various available calibrations), and a thermal valve. The presence of an additional latch cylinder ensures the possibility to open the sash for periodic maintenance and cleaning activities. The device can be connected to a remote pneumatic opening without any additional accessories.
NSHEV Free Smoke is a device for opening only in case of emergency and requires manual closing from the roof, while electric opening can be used for daily ventilation.
