PRODUCT DESCRIPTION
ArChine Refritech RAB 68 is a high quality synthetic alkylbenzene (AB) refrigeration lubricant and is intended for particularly arduous conditions. The lubricant is designed to be used with halogenated refrigerants in both refrigeration and air-conditioning applications. ArChine Refritech RAB 68 is an excellent lubricant for systems using R-22, R-123 and R-502. This oil may also be used where high refrigerant lubricant solubility is required. ArChine Refritech RAB 68 may be recommended for use in piston compressor refrigeration systems.
Some advantages of using the ArChine Refritech RAB 68 over the traditional mineral oils are:
Better Oil Return Superior Chemical and Thermal Stability
Better System Efficiency Lower Foaming Tendency
Lower Floc Point Excellent Miscibility
Superior Cleanliness
