Heptafluoropropane (HFC-227ea, FM-200) is a colorless, odorless, non-conductive and non-secondary pollution gas, which has the characteristics of cleanliness, low toxicity, good electrical insulation and high fire extinguishing efficiency. In particular, it has no damage to the ozone layer, short residual time in the atmosphere, and its environmental protection performance is obviously better than halon. It is a clean gas fire extinguishing agent successfully developed so far and is considered as a substitute for halon 60. The automatic fire extinguishing system of heptafluoropropane is a modern intelligent automatic fire extinguishing device integrating gas fire extinguishing, automatic control and fire detection, which conforms to DBJ 15-23- 1999 Design Code for Clean Gas Fire Extinguishing System of Perfluoropropane (HFC-227ea) and ISO 14520-9 Gas Fire Extinguishing System. An automatic heptafluoropropane fire extinguishing system consists of a storage bottle group, a storage bottle group frame, a liquid flow check valve, a collecting pipe, a selection valve, a tee joint, a reducing tee joint, an elbow, a reducing elbow, a flange, a safety valve, a pressure signal transmitter, a pipe network, a nozzle, a medicament, a fire detector, a gas fire extinguishing controller, a audible and visual alarm, an alarm bell, a deflation indicator lamp and an emergency start-stop button.

Automatic, manual, mechanical emergency manual and emergency start/stop four control modes. Common heptafluoropropane gas fire extinguishing systems include pipe network type, cabinet type and suspension type. These three types also belong to the internal storage pressure heptafluoropropane gas fire extinguishing system, and the transportation distance is within 30 meters. There is also an external storage pressure heptafluoropropane gas fire extinguishing system, and the transportation distance can reach 150 meters. Wu Xing Fire Department reminds you to choose a gas fire extinguishing scheme, and don't be blind. Generally, the appropriate gas fire extinguishing scheme is selected according to the size and structure of the protected area.
