R23 is an HFC retrofit refrigerant for R-13 and R-503 in very low temperature applications [below -40°F to -100°F (-40°C to -73°C)] such as medical freezers and environmental chambers. It can be used in new systems as well as to retrofit existing systems.
R23 refrigerant, ultra-low temperature refrigerant trifluoromethane, aliases: HFC23, HFC-23, F23, F-23. As a widely used ultra-low temperature refrigerant, R23 is mainly used in environmental test chambers/equipment (cold and thermal shock tester), freeze dryer/freeze dryer, ultra-low temperature refrigerator or freezer, blood bank refrigerator, biochemical test chamber and other cryogenic equipment (Including scientific research refrigeration, medical refrigeration, etc.), it is more common in low-temperature grades used in these cascade refrigeration systems. Trifluoromethane can also be used as a gas fire extinguishing agent, with the characteristics of cleanliness, low toxicity and good fire extinguishing effect.
