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. Applications and Compressor Type Propylene Refrigeration Oil-flooded rotary screw compressors Liquid ring vacuum pumps Other applications requiring an oxidative and thermally resistant lubricant Features and Benefits Hydrocarbon miscibility Work well with hydrocarbon gas in industrial refrigeration systems Oxidatively stable Longer system life Low volatility Reduced maintenance, reduced top-up High viscosity index Wide temperature range of operation Excellent lubricity Increased efficiency, reduced cost of operation
