Klüber Summit PGS compressor oils are based on polyalkylene glycols and special additives. In high-pressure piston compressors for natural gas or hydrocarbon process gas, mineral oils are easily absorbed into, and diluted by, the gas stream. By contrast, Klüber Summit PGS compressor oils are extremely resistant to such effects. The extremely high viscosity index of Klüber Summit PGS compressor oils 68 …, 150 ensures good lubrication in a wide range of temperatures.
