SINOPEC 4529 Synthetic Refrigeration Compressor 0il is blended with synthetic base oil and additive of high efficiency by multiple processes.
Advantages
♦ Good chemical stability and thermal stability, preventing oil from deteriorating under high temperature or in chemical medium
♦ Hydrophilic anti-wear performance, reducing wear of refrigeration compressor
♦ Low hydrophilic, preventing capillary from blocking
♦ High electrical insulation performance, ensuring application safety
♦ Perfect intersolubility with refrigerant R134a, no hydrolization and corrosion, ensuring normal operation of compressor
Performance
♦ Accredited by the material test from the technical center of FAW
Applications
♦ Suitable for refrigeration compressors taking R134a as refrigerant of reciprocating, inclined disc, rotary vane and scroll types for mobile and automotive air conditioners
♦ Suitable for same type of domestic air conditioner, refrigeration compressors of refrigerator and screw and centrifugal type industrial refrigeration machines taking R134a as refrigerant.
