Honeywell Genetron® AZ-50 Refrigerant
Categories: Fluid

Material Notes: Genetron® AZ-50® refrigerant (an azeotropic mixture of HFC-125 and HFC-143a, assigned R-507 by ASHRAE) was developed by Honeywell to serve as a long-term substitute for the refrigerant R-502. This patented, environmentally safe, non-ozone-depleting substitute possesses similar energy efficiency and capacity characteristics to R-502 and has an intrinsically low toxicity. Genetron AZ-50 has higher energy efficiency than other R-502 alternatives, due in part to superior heat transfer characteristics. Genetron AZ-50 is an excellent refrigerant choice for low- and medium-temperature refrigeration applications. Genetron® 404A is a refrigerant blend made up of HFC-125, HFC-143a, and HFC-134a and assigned the refrigerant number R-404A by ASHRAE. Like Genetron AZ-50, Genetron 404A is a non-ozone-depleting long-term alternative to R-502 that is well suited for low- and medium-temperature refrigeration applications.

Applications: In commercial refrigeration, Genetron AZ-50 and Genetron 404A serve a wide range of applications including supermarket freezer cases, reach-in coolers, display cases, transport refrigeration, and ice machines. These refrigerants may also be used to replace R-502 in a number of specialty applications. Genetron AZ-50 and Genetron 404A are suitable for both new equipment and retrofitting existing R-502 commercial refrigeration systems. Generally, there will be few, if any, equipment changes necessary to optimize the performance of Genetron AZ-50 or Genetron 404A refrigerants in these applications. For retrofitting commercial systems, refer to bulletin G525-100, Genetron Refrigeration Retrofit Guidelines.
