Refrigerant R227ea Gas

Under normal temperature and pressure, Heptafluoropropane(HFC227EA) is a kind of colorless gas, and is a compressed liquefied gas to be stored in culinders. Heptafluoropropane(HFC227EA) extinguishant is an ideral substitute of Halon 1301, and is clean, low poisonous, and has a good fire-protecting effect. It is mainly used in total-flood extinguishing system.
