Product information

Klüber Summit PGI lubricants 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 PGI compressor lubricants are extremely resistant to such effects.


Klüber Summit PGI compressor lubricants are designed for rotary screw and piston compressors used in the compression of propane. They are also suitable for refrigeration compressors where propane is the refrigerant. Because of the variety of gas stream compositions and other operating conditions, please contact your local Klüber sales representatives for specific viscosity recommendations.


– For the lubrication of propane compressors and refrigeration compressors with propane as the refrigerant – Compared with mineral oils, extremely resistant to dilution and absorption by hydrocarbon gas stream

Directions for use

Drain as much of the previously used compressor oil from the system as possible, making sure that the oil is drained while still warm. Do not forget to drain coolers, separator tanks and all lines. Next, clean or preferably change the filters. Then recharge with the appropriate Klüber Summit PGI oil. We recommend attaching a label indicating the type of lubricant used and the filling date to the lubricant filter or the compressor cover. Compatibility with materials To the best of our knowledge, the Klüber Summit PGI compressor oils are compatible with NBR (acrylonitrile content > 30 %), EPDM, MVQ (silicone rubber), PTFE and polyurethane foams. They can also be used with paints on an epoxy or phenolic basis. It is not advisable to use these products together with acrylic paints, polyurethane vanishes and synthetic materials on a PVC, polycarbonate and ABS basis.
