HFC-R407A Refrigerant (Low-GWP Retrofit Solution for R404A/R22)
HFC-R407A is a near-azeotropic HFC blend (R32/R125/R134a) designed as a low-glide, drop-in replacement for R404A and R22 in medium-temperature refrigeration systems. With zero ODP and a 30% reduced GWP (GWP≈2100) versus R404A, it complies with global phasedown regulations while maintaining comparable cooling capacity and operational performance.
Key Technical Advantages:
Optimized temperature glide (<5°C) minimizes system adjustment requirements
Near-identical operating pressure to R404A simplifies retrofit process
POE oil compatibility eliminates oil change requirements in most conversions
Non-flammable (ASHRAE A1 classification) for unrestricted application
