Advanced Synthetic Gas Compressor Oil
Application Shell Gas Compressor Oil S4 RN 68
Rotary screw gas compressors. Shell Gas Compressor Oil S4 RN is suitable for shaft and rotor lubrication of rotary screw compressors used for low pressure compression of natural gas.
LPG bottling. Shell Gas Compressor Oil S4 RN is suitable for use in rotary screw compressors used for bottling LPG up to 40 bar pressure
LPG and LNG vehicle fuelling. Suitable for use in compressors handling natural and petroleum gas for vehicle fueling applications
Multiple gas transportation vessels. Shell Gas Compressor Oil S4 RN is suitable for compressing a wide variety of hydrocarbon gases. When used in marine cargo compressors, there is no need to change lubricant with a change in gas being transported
Performance, Features & Benefits of Shell Gas Compressor Oil S4 RN 68 are:
- Extended maintenance intervals. Shell Gas Compressor Oil S4 RN has reduced hydrocarbon gas solubility which results in reduced viscosity loss (or increased viscosity retention) in comparison to mineral oil based products which can help provide extended service intervals and reduced maintenance costs.
- Outstanding wear protection. The low hydrocarbon gas solubility and associated low viscosity loss also results in retention of a stronger lubricant film on the screws. This ensures excellent sealing, and helps deliver low levels of corrosion and wear.
- Maintaining system efficiency. The low hydrocarbon gas solubility and associated low viscosity loss ensure excellent sealing between the two rotors at the point of mesh. Excellent lubrication of the rotor shaft bearings is also maintained.
Compatibility & Miscibility of Shell Gas Compressor Oil S4 RN 68 are:
- Seal Compatibility. Shell Gas Compressor Oil S4 RN may be used with most common seal and packing materials, including butyl, nitrile, neoprene and Viton seal materials
- Change-over Procedure. Shell Gas Compressor Oil S4 RN contains polyalkylene glycols and is not compatible with mineral oils or most other synthetic lubricant types. Care should be taken when changing from such products to Shell Gas Compressor Oil S4 RN.
Product Description Shell Gas Compressor Oil S4 RN 68
Shell Gas Compressor Oil S4 RN has been specially developed for lubrication of rotary screw compressors handling natural gas and other gases at low pressure. It is based on polyglycol base fluids and offers significant benefits over mineral oil-based products
