Compressor Oil - Refrigeration - Engen
A high quality napthenic mineral oil specifically selected for use in reciprocating and rotary refrigeration compressors. Due to its excellent fluidity at very low temperatures, the use of Genfreeze 32 ensures that evaporator tubes are kept clean to improve heat transfer therefore saving energy and related costs, while also reducing downtime ...
P-compressors are built to operate round the clock for all your oil-free high pressure applications. Thanks to 3 and 4 compression stages (with pressure ratios up to 42 bar(e) ), they perform in the most stringent environments.

Oil-free Refrigeration Compressors versus oiled compressors
A significant factor that affects chiller performance over time is the oil used by the chiller’s compressor. This article discusses the impact of oil on chiller compressors and examines the performance of variable-speed centrifugal semi-hermetic compressors with oil-free magnetic bearings over a 10-year period in two real-world applications.

How Does An Air Compressor Work - Kaishan Compressor USA
In an oil-free compressor, no oil is used to drive the compression process. The two rotaries in an oil-free model are controlled by gears. Without oil to serve as a chamber sealant, compressors of this type are not as capable of reaching high levels of pressure.

Properties of Oil and Refrigerant Mixtures
A refrigeration compressor contains highly loaded mechanical contacts that have to be lubricated. The lubricant used in refrigeration compressors consists of an oil and refrigerant mixture, and the refrigerant concentration can be up to 40 wt%.

How oil-free rotary screw air compressors work | the
Gearbox Oil. Yes, there is oil in an oil-free compressor. But it’s completely separated from the compressed air side. Oil is used to lubricate the gears, the bearings inside the gearbox, and the bearings and the timing gear inside the compressor elements. On bigger and air-cooled compressor, the oil is also used to cool the compressor elements.
