DewGas HFC-227ea
HFC-227ea is a high-performance clean agent fire suppression solution that provides rapid, reliable protection for people and critical assets, achieving effective fire knockdown in 10 seconds or less. It is a colorless, odourless, electrically non-conductive agent stored as a liquefied compressed gas and discharged as a clear vapor, leaving no residue and allowing immediate system recovery without cleanup. Suppression works through cooling and chemical interruption without reducing oxygen, making it safe for normally occupied spaces and effective against Class A, B, and C fires. With zero ozone depletion potential and compliance with NFPA 2001 and EPA SNAP, HFC-227ea is the trusted global replacement for Halon 1301 in modern clean agent systems.
