2.HFC-227ea is a clean extinguishing agent, which would completely vaporized in the air, 

and well insulated. Its total flooding mode is applicable to electric fire, liquid fire or fusible 

solid fire, solid surface fire, gas fire which gas supply is cut before extinguishing. And it is 

able to protect computer rooms, communication rooms, substation rooms, hi-tech device 

rooms generator rooms, gasoline storerooms, combustible chemical storerooms, libraries, 

data rooms, archives, treasuries, etc. We manufacture HFC-227ea system that is well 

structured, reliable, and widely applied to computer rooms, archives, program control exchange 

engine rooms, TV broadcast center, financial organizations and government departments.
