R-422B Refrigerant (HFC, R-22 Replacement)
R-422B Refrigerant – Reliable R-22 Service Blend
R-422B refrigerant is an HFC blend engineered as a cost-effective service replacement for R-22. It is commonly used in both residential and commercial systems where R-22 is no longer available or allowed. R-422B provides similar cooling performance while eliminating ozone depletion potential, making it a practical option for contractors servicing older equipment.
Common Applications
- Residential and light-commercial A/C systems originally charged with R-22
- Medium-temperature refrigeration units
- Service and maintenance of legacy cooling systems
Cylinder Sizes & Packaging
- 25 lb cylinder (standard service size)
Key Advantages
- Drop-in replacement for many R-22 systems with minimal modifications
- Zero ozone depletion potential
- Lower discharge temperatures than R-22, helping extend compressor life
Important Notes
- Not identical to R-22: While designed for retrofits, system adjustments (such as oil compatibility checks) may be required.
- Primarily for servicing existing systems: Not used in new OEM equipment.
- Certification: EPA Section 608 certification may be required for purchase.
