CPI-4600 is a series of Propylene Compressor Lubricants for the refrigeration industry. It is available in various viscosity grades; CPI-4600-68, and CPI-4600-100.
The CPI-4600 Series is manufactured using polyalphaolefin (PAO) synthetic base fluids which give excellent low temperature, wax-free properties. CPI-4600-68 and 4600-100 have superior thermal and oxidative stability, which enables them to operate over a wider temperature range than standard mineral products. These low volatility refrigeration oils are fully miscible with hydrocarbon gases and are also compatible with mineral based lubricants too.
Applications of the CPI-4600 Series
CPI-4600-68 and CPI-4600-100 can be used in propylene refrigeration applications including liquid ring vacuum pumps, oil flooded rotary screw compressors and any other application that requires a thermally resistant lubricant. They have a low pour point which prevents these lubricants from congealing in refrigeration lines and a high film strength helps to provide lubricity, even when they are diluted with the refrigerant in use.
CPI Fluid Engineering in partnership with Lubrizol
The 4600 series is manufactured by CPI Fluid Engineering, a world leader in the development and production of synthetic lubricants and operate in Europe, North America, Africa and Asia Pacific, in partnership with Lubrizol. They work extremely well in industrial refrigeration systems with hydrocarbon gas. Their low volatility and excellent lubricity all the user to reduce maintenance down time whilst increasing efficiency. Purchase CPI refrigeration oils today from the UK’s number one Oil-Store.
