# Klüber Summit PGS 2

### Klüber Summit PGS 2 is a Synthetic gas compressor oils.

– For the lubrication of piston, screw-type and rotary vane compressors for natural and process gas
– Compared with mineral oils, extremely resistant to dilution and absorption by hydrocarbon gases
– Klüber Summit PGS-2 is ideal for heavy gases (densities > 1.5 g/cm³)

#### Description

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 …, 460 ensures good lubrication in a wide range of temperatures.

#### Application

Klüber Summit PGS compressor oils are suitable for piston, screw-type and rotary vane compressors for natural or process gas.

Klüber Summit PGS-2 is ideal for hydrocarbon gases of densities greater than 1.5 g/cm³ because this product is extremely resistant to dilution and absorption by hydrocarbon gases.

Because of the variety of gas stream compositions and other operating conditions, please contact your local Klüber sales representative for specific viscosity recommendations.

#### Application notes

Drain as much of the old 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 PGS compressor oil.

We recommend attaching a label indicating the type and filling date of the lubricant to the filter or the compressor cover.

#### Compatibility with materials

To the best of our knowledge, the Klüber Summit PGS 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.
