Genetron® 404A (HFC-404A) is a non-ozone depleting compound designed to serve as a long-term alternative to Genetron® 502 (CFC-502) and Genetron® 22 (HCFC-22) in low- and medium-temperature commercial refrigeration applications.
Applications where Genetron® 404A is a suitable retrofit refrigerant include supermarket freezer cases, reach-in coolers, display cases, transport refrigeration and ice machines.
Genetron® 404A has been designed as a substitute for Genetron® 502, but it is not a drop-in replacement. Mineral oils and alkylbenzene lubricants, which have been used traditionally with Genetron® 502, are immiscible with Genetron® 404A.
