R-449A Refrigerant (HFC/HFO Blend)
R-449A Refrigerant – Retrofit Blend with Lower GWP
R-449A refrigerant, also known as Opteon™ XP40, is an HFC/HFO blend designed to replace high-GWP refrigerants like R-404A and R-507. It delivers lower environmental impact while maintaining reliable performance in commercial refrigeration applications.
How R-449A Compares
| Feature | R-404A / R-507 | R-449A |
|---|---|---|
| Global Warming Potential (GWP) | ~3900 | ~1300 (≈67% lower) |
| Applications | Commercial refrigeration, transport | Commercial refrigeration, transport (retrofit & new) |
| Flammability (ASHRAE) | A1 (non-flammable) | A1 (non-flammable) |
| Energy Efficiency | Baseline | Improved efficiency in many systems |
Applications
- Supermarkets and grocery stores
- Cold storage warehouses
- Transport refrigeration
- Food service refrigeration systems
Cylinder Sizes
- 25 lb cylinder (standard service size)
Key Considerations
- Retrofit capable: Can replace R-404A and R-507 in many existing systems with proper adjustments.
- Lower environmental impact: Much lower GWP than legacy HFC blends.
- Certification: EPA Section 608 certification required for purchase.
