[Usage] R23 is also known as HFC-23, Fluoroform, Freon 23. It is used as low temperature refrigerant and fire extinguishing agent. HFC-23 has been used in the past as a replacement for Halon 1301[cfc-13b1] in fire suppression systems as a total flooding gaseous fire suppression agent.

[packing] Pressure bottle, 30kg/cylinder, 380kg/cylinder, or other requirements. R23 has two kinds of packing for refrigerant and fire extinguishing agent.
