Genetron® AZ-20 (R-410A) Refrigerant | HFC Azeotropic Blend for High-Efficiency Cooling Systems

Genetron® AZ-20 (R-410A) is a high-performance, non-ozone-depleting HFC refrigerant blend developed by Honeywell to replace R-22 in new air conditioning and refrigeration systems. As an azeotropic blend of HFC-32 and HFC-125 (50/50 ratio), it delivers excellent thermal stability, zero glide, and high energy efficiency — making it the go-to refrigerant for next-generation residential and commercial cooling systems.

???? Not for retrofit use — specifically designed for new equipment only.
