Alkylbenzene refrigeration lubricant
PRODUCT DESCRIPTION
GB-3137-68 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. GB-3137-68 is an excellent lubricant for systems using R-600a£¬R-22, R-123 and R-502. This oil may also be used where high refrigerant lubricant solubility is required. GB-3137-56 may be recommended for use in piston compressor refrigeration systems.
Some advantages of using the GB-3137-68 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
