Heptafluoropropane

Heptafluoropropane (HFC-227ea/FM200) is also known as Hailong gas 1,1,1-2-3,3,3-heptafluoropropane. Its CAS number is 431-89-0[1] and its structural formula is CF3CHFCF3. It is a colorless, odorless gaseous halogen carbon (halocarbon) and is called HFC-227, HFC-227ea, FE-227, and FM-200. Its chemical formula is C3HF7 and is slightly soluble in water (260 mg/l). ]

Heptafluoropropane is in gaseous state at room temperature, colorless, odorless, non-conductive, non-corrosive, and has no environmental restrictions. It has a short atmospheric retention period. The fire extinguishing mechanism is mainly to interrupt the combustion chain, and the fire extinguishing speed is extremely fast, which is beneficial for the rescue protection of precision electronic equipment and valuables. Heptafluoropropane fire extinguishing devices are divided into two types: with pipe network and without pipe network (cabinet type, hanging type).

02 Application place Heptafluoropropane gas fire extinguishing equipment is used in computer rooms, communication rooms, physical and chemical laboratories, precision instrument rooms, valuables warehouses, generator rooms, substations, libraries, archives rooms, important databases, traffic command centers, medical equipment rooms, banks, museums, flammable chemicals warehouses and other places.
