The CPI -4600 Series compressor lubricants are formulated using premium polyalphaolefi n (PAO) synthetic base fluid, coupled with a high-performance additive package.
These compressor lubricants feature excellent thermal and oxidation stability enabling them to operate over a wide range of temperatures without coking, deposit formation or corrosion. The lubricants have low volatility and exhibit excellent miscibility with hydrocarbon gas and good compatibility with mineral oil lubricants.
The CPI-4600 Series are recommended for refrigeration services due to its excellent low-temperature properties. They are wax-free as they are synthetic. A low pour point prevents lubricants from congealing in refrigeration lines. High film
strength provides lubricity even when diluted with refrigerant.
