Natural ventilation automatic opening mechanism CO2 NSHEV

These are pneumatic opening devices. The basic principle is that, in the case of fire at a certain temperature, the temperature ampule that activates the CO2 cartridge is activated, the push gas fills the pneumatic cylinder, and the piston rod opens the skylight. Depending on the requirements of the particular project, the activation of CO2 cartridge may be carried out by means of a temperature ampule or by means of a fire centre or a fire signaller, such as hand-held indicators, smoke sensors, and the like. The fire centre can be electric (connection to an electrical activator) or a centre with larger CO2 cartridges (connection via pipe (copper) installations). CE certified systems, MAX skylight dimension 200 x 250 cm, option of opening from the ground (‘OPEN – CLOSE’), CO2 cartridges are suitable for single use only and must be replaced after activation, Possibility of activating temperature ampules at different temperatures (68°, 93°, 141°, 183°, …), The CO2 opening can be combined with an electric motor opening for ventilation, 2 types of certified opening devices available (type ‘G’ and type ‘J’), Snow load up to SL 750 N/m2, Simple installation of the system (adjustable valves of different types, deflectors, aluminium opening frames, opening mechanism) Snow load SL: up to 1500 Wind load WL: up to 2000 Opening time: under 60 s Reliability of operation: Re 10000 Heat resistance: B300 Operation at low temperatures: T(-15) Reaction to fire: Aluminium A1, Polycarbonate B-s1, d0, sealants F The aerodynamic surfaces (Aa) of the hatches have been tested at the specialised and accredited institute of IFI Aachen Germany.
