SUMMIT NGL

Klüber Summit NGL compressor lubricants are based on polyalkylene glycols and special additives.

In high-pressure reciprocating compressors pumping natural gas or hydrocarbon-based process gas, petroleum based lubricants are easily absorbed into the gas stream and diluted by the gas. Klüber Summit NGL lubricants are extremely resistant to hydrocarbon dilution and gas stream absorption.

The extremely high viscosity index of both products ensures efficient lubricity in a wide temperature range.

The Klüber Summit NGL series is designed for high pressure reciprocating compressors pumping natural gas, carbon dioxide or process gases (e.g. hydrogen, helium, nitrogen).
The Klüber Summit NGL series is designed for all oil-lubricated components in reciprocating compressors, e.g. cylinder, highpressure packing, bearings and engine. Please observe the manufacturer's viscosity specifications.
Owing to its low pour point, Klüber Summit NGL-444 is also suitable in case of very low ambient temperatures.
Klüber Summit NGL 555 and Klüber Summit 777 can be used for the lubrication of engines, cylinders and high-pressure packings according to the gas flow and the manufacturer's specifications.
Klüber Summit NGL-888 is particularly suitable for injection compressors used in oil and gas fields because it is water soluble and compatible with well-bore treatment fluids.
Due to the varying make-up of gases and operating conditions, please contact your local Klüber representative for specific product recommendations.
The Klüber Summit NGL series is also commonly used for Hydrogen applications.

For high pressure reciprocating compressors pumping natural gas, carbon dioxide or process gases
Extremely resistant to hydrocarbon dilution and absorption and good chemical resistance to process gases
Very high viscosity index, thus low viscosity change in a wide temperature range
Very good wear protection for longer component lifetime
Low residue formation for longer lifetime of valves and piston rings
