PyroGen has a knock-down effect. Its extinguishing action is achieved primarily by interfering chemically with the fire reaction and secondarily by thermal cooling. Such low design concentration coupled with almost instantaneous extinguishing action makes PyroGen one of the most efficient agents currently available. Apart from being effective, PyroGen is very simple in installation and operation. Pressurised cylinders and propellant gases are not necessary since the pyrogenic mechanism of aerosol generation provides sufficient energy for a rapid discharge and efficient distribution.
Aerosol is self-generated upon activation of the system.
The PyroGen system simply consists of a series of canisters called MAG generators, strategically placed within the risk area and electrically connected to most types of manual or automatic fire control panels. Operation of PyroGen system could be either electrical or thermal. When an electrical current is supplied to the electrical ignition device of Pyrogen generator, the solid aerosol forming composition undergoes a combustion reaction to produce its fire extinguishing aerosol. There is an additional mechanism of activating Pyrogen generator via a built-in pyrotechnic fuse which ignites when in contact with flame or subjected to high temperatures. Ignition of fuse leads to an ignition of the solid aerosol forming composition.
