Heptafluoropropane gas (HFC-227ea) fire extinguishing system 
 We supply heptafluoropropane gas fire extinguishing system 
 Heptafluoropropane gas fire extinguishing system is currently in China and elsewhere has been widely used. Fire extinguishing agent is a colorless, odorless gas, the depletion of ozone layer on the self-potential is zero, in line with environmental requirements, a clean, low toxicity, good insulation, high performance characteristics of fire, fire extinguishing agent is an ideal substitute . 
 Heptafluoropropane gas fire extinguishing system has the design parameters of a complete, comprehensive, accurate and reliable long-term storage of work does not leak, installation is simple and easy operation and maintenance. 
 Heptafluoropropane gas fire extinguishing system consists of automatic alarm controller, storage device, the valve drive select valve, check valve, pressure markers, frames, nozzle, pipe network and other components. According to requirements, the system can be composed of independent units, combined distribution system were implemented on a single area and multi-zone fire protection. 
 Heptafluoropropane gas fire extinguishing system is mainly for computer rooms, telecommunications centers, underground engineering, offshore oil, libraries, archives, library treasures, power distribution room, fire protection and other important places.
