National Refrigerants, Limited (NRL) is an independent worldwide distributor
of refrigerants and all associated refrigerant management services.

Composition: A blend of HFC refrigerants R125, R134a and hydrocarbons R600 and R601 (19.5/78.5/1.4/0.6 wt%)

Application: R437A is suitable to replace HCFC refrigerants that replaced R12 in automotive, stationary air conditioning and direct expansion medium temperature stationary refrigeration systems (R401A/B and R409A/B).

Performance: R-437A provides better cooling capacity and comparable energy efficiency to R12 but with lower discharge temperatures.

Lubricant: The hydrocarbon component in R-437A helps promote oil return in systems containing mineral oil or alkylbenzene. Although HFC refrigerants won’t mix with these oils, the hydrocarbon addition thins the oil and keeps it moving around the loop. More complicated piping arrangements or large hold-up volumes may still require some oil be changed to POE.
