A-Gas R32 HFC Refrigerant
R32 is an HFC refrigerant used as a replacement for R410A in new air-conditioning and low-temperature refrigeration equipment.
With a lower GWP of 675, R32 provides a lower-GWP alternative to R410A while offering slightly better energy efficiency and similar boiling temperature characteristics. A-Gas notes that R32 is a preferred replacement for R410A in new equipment, but it is not suitable as a retrofit refrigerant due to its system and handling requirements.

Safety & Documentation
R32 must be handled by appropriately licensed refrigeration and air-conditioning technicians. A-Gas notes that R32 is mildly flammable with an A2L safety classification, so different charging and recovery procedures are required compared with non-flammable refrigerants.
R32 is not a retrofit replacement for R410A. Only use it in equipment specifically designed and approved for R32. Compressors must be charged with polyolester oils, and technicians should confirm system-specific requirements with the equipment or compressor manufacturer.
Store cylinders in a cool, dry and well-ventilated area, away from direct sunlight. Always refer to the current A-Gas Safety Data Sheet and equipment manufacturer guidance before use.
A-Gas R32 is a practical lower-GWP HFC refrigerant for new air-conditioning equipment and compatible low-temperature refrigeration systems designed for R32 operation.
