Industrial chillers-(singde) the basic requirements for the selection of lubricating oil!

Lubricating oil is to provide lubrication and cooling conditions for the moving parts of industrial chillers. The lubricating oil used in refrigeration compressors is usually called refrigerating oil, which is a highly refined special lubricant. Lubricating oil is used in the refrigeration compressor to lubricate the moving parts and reduce the friction between the surfaces of the moving parts.
