Compressor Oil

Refrigeration compressor oil helps transfer refrigerants more efficiently while lubricating and protecting machinery, especially the compressor, in high-temperature and high-pressure environments. The lubricant’s role in minimizing friction and wear and preventing oxidation is crucial because, without proper lubrication, the efficiency of the entire refrigeration system would decrease due to loss in pressure and friction caused by heat. It also provides a sealing effect, preventing the leakage of gas or liquid, as well as cooling effects, such as reducing heat caused by excessive friction. 

Refrigeration compressor oils have specific requirements to maintain system efficiency, and one crucial factor is lubricant-refrigerant miscibility, which is an evaluation of how well the refrigeration compressor oil mixes with the refrigerant. This is tested by observing the low-temperature point at which they separate, quantified as the “floc point,” and must meet the appropriate standards depending on the type of refrigerant and the hardware characteristics. The oil and refrigerant should not mix too well, as this could reduce viscosity, nor too poorly, as this could lower system efficiency.  

Other performance requirements include wear protection, thermal stability and chemical stability to protect the machinery from an extreme environment where rapid change in temperature and pressure occurs.

PSL, we provide all kinds of Mineral Oil (MO) and also synthetic oil like polyol ester (POE), polyalkylene glycol (PAG), alkylbenzene (AB), and polyalphaolefin (PAO) oils.
