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

Composition: A blend of HFC refrigerants R-23 and R-116 (46/54 wt%))

Application: R-508B is intended for very-low-temperature refrigeration systems, typically the low stage of a multi-stage system. R-508B has properties similar to R-503 and can be used to replace either R-13 or R-503 in an existing system.

Performance: The discharge temperature does not increase significantly compared to R-13, in contrast to the increase seen with R-23.

Lubricant: POE lubricants should be used and it may still be necessary to charge hydrocarbon oil additives to ensure proper oil return. Check with OEM for specific oil and charging recommendations.
