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


Developed for use in low temperature refrigeration (the evaporator pressure stays out of vacuum down to -40°F). R-502 offers lower discharge temperature and improved capacity compared to R-22. Commercial refrigeration systems can perform low temperature refrigeration in a single stage with relatively inexpensive compressors. Since the phase-out of R-502 in 1995, service quantities are still available through recovery and reclaim operations.
