Chemori227 Clean Agent
Chemori227, more commonly known as HFC-227ea, aims at suppressing fires by removing its heat source. It is safe around occupied areas, non-conductive, non-corrosive, and free from residue.
HFC-227ea requires less agent to extinguish a flame compared to FK-5-1-12. Consequently, fewer or smaller cylinders are needed for installation, resulting in a cost effective approach. HFC-227ea has a low toxicity rating and does not pose a direct threat to individuals. When following manufacture guidelines, HFC-227ea is safe for occupied areas.
Some applications for HFC-227ea include telecommunications, data centers, military equipment, and medical applications, to new a few.
