R448A Refrigerant (Next-Generation Low-GWP Replacement for R404A & R22)
R448A is a non-ozone-depleting HFO/HFC blend (R32 / R125 / R134a / R1234yf / R1234ze) designed as a sustainable alternative to R404A and R22 in commercial refrigeration and air conditioning. With a Global Warming Potential (GWP) of ~1273, R448A offers more than a 65% reduction in GWP compared to R404A, while maintaining excellent energy efficiency and refrigeration capacity. Its low temperature glide and reliable system compatibility make it an ideal choice for both new equipment and retrofit applications.
Key Technical Advantages:
Zero ODP and significantly reduced GWP (~1273 vs. ~3922 for R404A)
Higher energy efficiency compared to R404A & R507A
Low temperature glide (~6 K) ensures stable and predictable performance
Compatible with existing POE lubricants for seamless retrofits
Approved by major compressor and equipment manufacturers
Lower discharge temperature extends compressor lifespan
