HFC-R427A Refrigerant (Zero ODP Drop-in Replacement for R22 Systems)
HFC-R427A is a non-ozone depleting, near-azeotropic refrigerant blend designed as a direct retrofit solution for R22 in existing air conditioning and refrigeration systems. With zero ODP (Ozone Depletion Potential) and a significantly reduced GWP of 2,130 (compared to R22's GWP of 1,810), it provides an environmentally responsible alternative that requires minimal system modifications while maintaining comparable performance.
Key Technical Advantages:
Excellent capacity matching (95-100% of R22 capacity) minimizes system reengineering
Low temperature glide (<4°C) ensures stable operation and easy troubleshooting
Direct drop-in replacement for most R22 systems with POE lubricants
A1 safety classification (non-flammable, non-toxic) per ASHRAE Standard 34
Good material compatibility with common metals and elastomers
