R-407A Refrigerant (HFC Blend)

R-407A Refrigerant – Retrofit Blend for Refrigeration

R-407A refrigerant is an HFC blend designed as a retrofit replacement for R-22 and R-404A in medium- and low-temperature refrigeration systems. Offering lower discharge temperatures and improved energy efficiency compared to older refrigerants, R-407A is used in supermarkets, food service equipment, and cold storage facilities.

Common Applications

  • Medium-temperature commercial refrigeration
  • Low-temperature supermarket and cold storage systems
  • Food service and restaurant refrigeration equipment

Cylinder Sizes & Packaging

  • 25 lb cylinder

Key Advantages

  • Retrofit capability for systems previously using R-22 or R-404A
  • Lower discharge temperature for extended compressor life
  • Zero ozone depletion potential

Important Notes

  • Not a drop-in: Retrofitting requires adjustments such as lubricant and component checks.
  • Primarily refrigeration use: R-407A is not typically used in residential A/C systems.
  • Certification: EPA Section 608 certification may be required for handling and purchase.
