R-407C Refrigerant (HFC, R-22 Replacement)
R-407C Refrigerant – HFC Blend for R-22 Retrofits
R-407C refrigerant is an HFC blend developed as a non-ozone depleting replacement for R-22 in air conditioning and refrigeration applications. With thermodynamic properties similar to R-22, it is commonly used in retrofit projects for existing systems, as well as in some OEM equipment designed prior to the industry’s transition to R-410A.
Common Applications
- Residential and light-commercial air conditioning systems
- Heat pumps
- Packaged A/C units designed for R-22 retrofits
Cylinder Sizes & Packaging
- 25 lb cylinder (standard service size)
Key Advantages
- Direct retrofit option for many R-22 systems
- Zero ozone depletion potential
- Similar operating pressures to R-22
Important Notes
- Retrofit requires system modifications. R-407C is not a drop-in replacement; filter drier, oil, and component adjustments may be necessary.
- Not commonly used in new equipment. Most modern systems use R-410A, R-32, or R-454B instead.
- Certification: EPA Section 608 certification may be required for purchase and handling.
