The BlazeCut T Series system uses HFC-227ea, which is an extremely effective, clean, and a people-safe extinguishing medium. BlazeCut T Series system operates automatically and independent of any power supply by detecting higher temperatures. When the temperature in the protected enclosure rises to a critical level, the detection tube melts down at the point where the affect of temperature is highest. The tube melts and creates a hole releasing the entire extinguishing agent stored in the tube directly onto the source of the fire.
