Application area
Rotary screw gas compressors:
- Gas Compressor Oil S4 RN 68 is recommended for lubricating the axes and rotors of rotary screw compressors designed to compress natural gas at low pressures.
- Filling LPG tanks
- Gas Compressor Oil S4 RN 68 is recommended for use in rotary screw compressors designed to fill household gas cylinders.
Refueling vehicles with liquefied natural and associated petroleum gas
- Gas Compressor Oil S4 RN 68 is suitable for use in compressors that compress natural and petroleum gas for refueling vehicles.
When replacing mineral oils with Gas Compressor Oil S4 RN 68 and vice versa, special procedures are necessary.
- Recommendations for using oil in areas not listed in this leaflet may be obtained from your Shell representative.
Benefits
- Low solubility of hydrocarbon gas in oil Gas Compressor Oil S4 RN 68 is specially formulated to reduce gas solubility. As a result, viscosity is reduced to a lesser extent compared to mineral-based products, and wear protection and equipment performance are improved. Maintenance intervals are extended, thereby reducing operating costs and downtime costs.
- Reliable lubricating film;
- A lower viscosity reduction contributes to the formation of a more reliable lubricating film on the parts of the equipment. Due to this, corrosion protection is increased and the wear rate is reduced;
- Approved by leading manufacturers of equipment for multiple gas transportation;
- When using the product in marine compressors for transporting liquefied petroleum gases, there is no need to change the oil depending on the gas transported.
