How Tercel Fire Extinguisher Works Tercel Aerosol Fire Suppression system (Tercel AFS) when electrically or thermally activated, products micron size dry particles of mainly potassium carbonates and gases. the mixture of aerosol propels itself through a chemical coolant and discharges from the generator into the protected area. The high rate of micron sized particles of aerosol homogeneous is achieved in several seconds and a long holding time help to prevent fire re- ignition. The extinguishing density of aerosol generators : ISO 15779: 2011 and MSC .1 1270(IMO) The Advantage of tercel Fire extinguisher AFS over the competitive products are its wide range operating temperature (-50 c.....+ 90 C)and high strength under impact loads and vibration stress. thus Tercel AFS is widely used for fire protection of various transport means and combat vehicles in addition to electrical, it and other application.
