Heptafluoropropane gas automatic fire extinguishing system
1.Brief introduction
HFC-227EA (HFC-227EA) fire extinguishing system is a kind of modern fire extinguishing equipment, mature technology, as an ideal replacement product of halogenated fire extinguishing system is widely used at home and abroad.Of seven fluorin propane is a colorless, odorless gas, the loss of ozone ozeme depletion potential (ODP) is zero, is approved by the ISO (international organization for standardization) clean gas fire extinguishing agent, with a clean, low toxicity, good electric insulation performance, high fire extinguishing efficiency, etc.
Of seven fluorin propane gas extinguishing equipment is mainly used in electronic computer room, telecommunications equipment, process control, industrial equipment, libraries, museums and galleries, clean room, anechoic chamber, emergency power facilities, flammable liquid storage area, also can be used in the production operation fire dangerous places, such as paint spraying production line, between the electrical aging, rolling machine, printing machine, oil switch, oil-immersed transformer, melt impregnating tank, tank, large generators, drying equipment, cement production process of pulverized coal bin, as well as the ship engine room, cargo hold, etc.
