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

Composition: A blend of HFC refrigerants R32, R125, R134a and hydrocarbons R600 and R601a (8.5/45/44.2/1.7/0.6 wt%)

Application: R-438A is intended to replace R22 in existing direct expansion systems where the expansion device capacity is very closely matched to the system capacity (predominantly water chillers).

Performance: In most cases R438A provides similar cooling capacity and energy efficiency to R22 while operating at significantly lower compressor discharge temperature but actual performance depends on system design and operating conditions.

Lubricant: The hydrocarbon component in R-438A 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.
