HFC23 Fire Extinguishing Agent is a hydrofluorocarbon (HFC). Chemically, it is trifluoromethane, CHF3. It does not contain bromine, like Halon 1301 (CF3Br), which is the component identified as contributing to the depletion of the earth’s ozone layer. With zero ozone depletion potential (ODP), HFC23 is environmentally preferred.
HFC23 is the preferred Halon 1301 replacement in total flooding and inerting applications where its low toxicity provides for improved safety margins, the protected space is large (approved for nozzle heights up to 25 feet), the cylinder storage area is remote from the protected space.
HFC23 is also an HFC retrofit refrigerant for R-13 and R-503 in very low temperature applications below -40°C to -73°C such as medical freezers, environmental testing chamber or blood bank refrigerator etc.
