PDS - QStar Refrigeration Compressor Oil

QStar Refrigeration Compressor Oil Series is a range of special refrigeration compressor oils, using highly refined base stocks with low carbon forming tendencies and good water separation properties. In hot applications, they may form small amount of soft, fluffy carbon, while the conventional paraffinic-based lubricants form larger amount of harder carbon. These oils have inherent low temperature characteristics and do not contain any pour point depressant additives that have been known to impair the performance of certain refrigerator systems.

QStar Refrigeration Compressor Oil Series exhibits very high thermal stability and good chemical stability with many commonly used refrigerants. They are non-reactive with typically encountered compounds in a refrigeration system. The products are available in a wide range of viscosity grades, of which the ISO VG 32, ISO VG 46 and ISO VG 68 are the most commonly used to meet the needs of residential and industrial refrigeration systems. These products are not recommended for use in breathing air compressors.
