- Heat pumps
- Small and medium chillers
Service and safety notes
- Near-azeotropic blend: negligible glide, but blends are still charged in liquid phase.
- 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.
R410A 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. According to Ministry presentations, new single split air conditioners containing less than 3 kg of HFC with a GWP of 750 or more are banned from the market from 2027. Always check the current legal text for exact dates and scope.
