In shortR407F was developed as a lower-GWP replacement for R404A and R22 in supermarket and commercial refrigeration. Today R448A and R449A are more common.

Where is R407F used?
- Supermarket refrigeration
- Cold rooms
- R404A and R22 retrofits
Service and safety notes
- Zeotropic blend, glide about 6.4 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.
R407F 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.
