Production

As one of most successful clean fire extinguishing agents currently, heptafluoropropane (code HFC-227ea) is colorless, odorless, non-conducting, and free from secondary pollution, has zero ozone depletion potential (ODP), and conforms to the requirements of Montreal Convention.

HFC- 227ea system is the optimal substitute for halon extinguishing systems in our country, and is characterized in high extinguishing speed, strong extinguishing capability, low extinguishing concentration, non conduction and low toxicity. As there is no toxic reaction at the maximum concentration (NOAEL) of 9% (V/V), it is especially suitable for places where people work. It is extensively applied to precious archive rooms like archives, bank vault, art museum and historical relic room; computer rooms, control rooms, distribution rooms and key combustible gas and liquid places. It can extinguish A, B, C types of fires, but not suitable for active metal such as potassium, sodium, magnesium and uranium, and metal oxides.
