1. System Introduction
HFC-227ea fire extinguishing-agent ,CF3CHFCF3 which is a clean, low toxic, isolated, effective product which makes no damages to the ozonosphere, it is a successfully developed gaseous fire-extinguishing agent until today. HFC-227ea is one of good replacement for the Halon fire extinguishing-agents.
HFC-227ea is effective with fully-immersing way to put out electrical fire, flammable liquid or soluble solid fire, solid surface fire, and gas fire which supply can be cut down before extinguishing. It is to be used in place with people working or gathering. HFC-227ea leaves no residua and is conducting medium free, these features make HFC-227ea irreplaceable in locations such as computer room, telecom machine room, power transmission room, Precision apparatus room, power room, gas and oil terminal, flammable chemical and book storage, document and file storage, gold vault, etc.
