In shortR417A is a drop-in replacement for R22 systems that does not require an oil change. The small butane content helps oil return.

Where is R417A used?
- Retrofit of R22 air conditioners and heat pumps
- Retrofit of R22 commercial refrigeration
Service and safety notes
- Zeotropic blend, glide about 5.6 K: always charge in liquid phase; after a large leak, recover and recharge the full system. Use dew point for superheat and bubble point for subcooling.
- Non-flammable and low toxicity (A1). A large leak in a closed room can still displace oxygen, so gas detection is recommended in small plant rooms.
- Never charge a system with a refrigerant other than the one on its nameplate; retrofits need manufacturer approval and oil and component checks.
- Charging, recovery and leak checks must be done and recorded by F-gas certified technicians.
R417A and regulations
Covered by Türkiye's Regulation on Fluorinated Greenhouse Gases (Official Gazette, 15 October 2024). HFC supply is being phased down with quotas, high-GWP gases are restricted earlier, leak-check intervals depend on the CO₂-equivalent charge, and handling requires certified technicians. Always check the current legal text for exact dates and scope.
