R-448A Refrigerant (HFC/HFO Blend)
R-448A Refrigerant – Low-GWP Replacement for R-404A and R-507
R-448A refrigerant is a modern HFC/HFO blend developed as a more sustainable alternative to high-GWP refrigerants such as R-404A and R-507. With a significantly lower global warming potential, R-448A helps meet current and future environmental regulations while maintaining strong performance in refrigeration applications.
Why Choose R-448A?
- Lower GWP: Approximately two-thirds less than R-404A.
- Energy efficiency: Improved system efficiency compared to older HFC blends.
- OEM-approved: Supported by many equipment manufacturers for new installations.
- Retrofit capable: Can be used to replace R-404A and R-507 in many existing systems.
Common Uses of R-448A
R-448A is primarily used in commercial refrigeration applications, including:
- Supermarkets and grocery stores
- Convenience store refrigeration systems
- Cold storage and food processing plants
- Transport refrigeration equipment
Cylinder Sizes & Packaging
- 25 lb cylinder (standard service size)
Key Considerations
- Not identical to R-404A: Retrofitting requires system evaluation and possible component adjustments.
- Classified as A1: Non-flammable under ASHRAE classification.
- Certification: EPA Section 608 certification required for purchase and use.
