Fire suppression Systems

Small-size GFFM Impulse-FD

Gas Fire-fighting Modules Impulse-FD are designed for fire suppression with the gas extinguishers ( Freon 125 and Freon 227ea ) fire classes A, B , C and electrical equipment. Main feature of this system is using fire detecting sensitive tube Fire DeTec ®(made by Rotarex, Switzerland), which is made from high-tech polymer. It allows high flexibility, resistance and long life. Fire DeTec ® tube is constantly under pressure. Polymer is melted in the fire place and starts up the extinguishing agent. After that the valve of the shutter-starting device opens and disperses fire-fighting gas. Depending on the type of system, the extinguishing gas is produced through the Fire DeTec tube ( for systems Impulse -FD-DLP) or through the distribution pipe (for systems Impulse -FD-ILP and Impulse -FD-ILP- EM) . Modules Pulse -FD-ILP- EM is also equipped with an electromagnetic activator for control of extinguishing agent startup. All modules can be fitted with a pressure switch to signal the pressure fall in the module.

Modules fire Impulse -FD-ILP modules are fully autonomous system. If the temperature in the sensitive tube is up to 110 ° C  the pressure in the chamber falls, valve opens and the extinguishing agent ( Freon 125, Freon 227ea ) starts up. Modules can be fitted with a pressure gauge pressure switch for signal actuation module. Cylinders are made of stainless steel of 2 and 5 liters.
