Gas Compressor Oils

Gas compression requires products which do not dilute the compressed gas. Mercury Gastop series provides excellent viscosity stability and therefore warranted lubrication properties.

Gascomp DE

Synthetic di-ester based compressor fluids for gas compressor applications

Gascomp DE are a combination of high-grade synthetic ester base fluids and special engineered additive systems. They are used successfully for the long-term lubrication of screw, rotary vane or reciprocating (piston type) compressors.

Application

Gascomp DE can be used successfully for compressing the following gases: Air, Butadiene, Carbon Dioxide (dry), Carbon Monoxide, Ethylene, Furnace (crack) Gas, Helium, Hydrogen, Hydrogen Sulphide (dry), Natural Gas, Methane, Nitrogen, Propane, Synthesis Gas, Sulphur Hexafluoride etc. The nominal operating range is –15°C to 230°C.Gascomp DE synthetic gas compressor lubricants offer high performance protection of compressors in extreme conditions: high load and temperatures, compressing reactive and dirty gases, intermittent operation, in warm or cold climates and in mobile applications.
