HFC-227ea fire extinguishing agent is colorless, odorless, non-conductive, and has zero depletion potential (ODP) on the ozone layer, which meets environmental protection requirements. HFC-227ea fire extinguishing agent has the advantages of high fire extinguishing efficiency, no pollution to equipment, good electrical insulation, and rapid fire extinguishing. It is an ideal substitute for halogenated alkane fire extinguishing agents.
HFC-227ea automatic fire extinguishing system has three control modes: automatic, electrical manual and mechanical emergency manual. The system is mainly composed of: automatic alarm and fire extinguishing control system, fire extinguishing agent cylinder kit, actuating cylinder kit, release device, selection valve, check valve, nozzle, piping system and other main components. According to the requirements of use, it can be composed of unit independent systems, combined distribution systems and other forms to implement single-zone and multi-zone fire protection.
It is mainly applicable to the fire protection of key units such as electronic computer rooms, telecommunications centers, underground projects, offshore oil production platforms, libraries, archives, treasure stores, power distribution rooms, etc.

-Low concentration of HFC
-227ea required means less visual obscurity and minimal risk to personnel.
-Small quantity of agent discharged minimises over pressurisation of the protection area.
-Max Safety for personnel due to low toxicity.
-High effective with 10 second discharge time when used with automatic detection.
-Prevent re-ignition as long as concentration levels are maintained.
-Two kinds of working pressure system are available,(25 bar / 360 psi and 42 bar / 600 psi).
