Clean Agent Automatic Fire Extinguisher System (FM200) Fire Fighting Equipment
HFC-227ea is a kind of colorless, tasteless, non-conducting gas fire extinguishing agent at normal temperature, which can be liquefied and stored at low pressure. Its density is about 6 times that of air. Its molecular formula is CF3CHFCF3, its brand name is HFC-227EA, and it is called FM-200 abroad. When the extinguishing agent is sprayed into the protected area, the extinguishing agent will decompose and produce active free radicals when it touches the flame or high temperature surface. The free radicals will capture the active substances generated in the combustion chain reaction, destroy the chain transmission in the combustion process, and finally achieve the purpose of fire extinguishing. This method belongs to chemical fire extinguishing, with little physical effects such as cooling, dilution or isolating the air. Because of its high fire extinguishing efficiency, no pollution to equipment, no damage to the atmospheric ozone layer and other advantages, it is currently the first choice to replace the alkyl halide fire extinguishing agent
