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 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 NSHEV Free Smoke is a device designed for emergency opening only and requires manual closing from the roof. The presence of the spoiler ensures the maximum aerodynamic performance Aa.
