Shell Corena S4 R 68
Advanced Rotary Synthetic Compressor Oil
Product Description
Shell Corena S4 R 68 is primarily an advanced synthetic air compressor oil incorporating a unique high performance additive system. It is designed to deliver the highest performance lubrication of rotary sliding vane and screw air compressors.
It uses an advanced additive system to provide excellent protection and performance for compressors running at pressures over 25 bar and in excess of 100C discharge temperatures with oil maintenance intervals of up to 12,000 hours. Shell Corena S4 R ISO 68 is also perfectly suitable to cover applications where a synthetic bearing & circulating oil or R&O oil (ISO VG 32-68) is needed.
Application
- Rotary sliding vane and screw air compressors
Shell Corena S4 R 68 is suitable for oil-flooded/oil injected, single or two-stage compressors, operating at pressures of in excess of 25 bar and with air discharge temperatures of over 100C (including intermittent operation under these conditions).
- Severe service conditions
May also be used where exceptionally high ambient temperatures are found, when the oil temperature cannot be reduced to normal levels. - ABB Turbochargers
The product is recommended for use in ABB turbochargers fitted to low and medium speed diesel engines used in marine and power generation applications. - Bearing & Circulating Oil
Perfectly suitable to cover applications where a synthetic bearing & circulating oil or R&O oil (ISO VG 32-68) is required and will provide benefits due to increased resistance to deposit formation, improved low temperature fluidity, and lowering equipment operating temperatures. When a higher viscosity grade synthetic oil is required, Shell Morlina S4 B grades is recommended for such applications.
Specifications, Approvals & Recommendations
Shell Corena S4 R ISO 68 is approved by ABB for use in VTR turbochargers, with a maximum oil change interval of 5000 hours (HZTL 90617, list 3a).
ISO 6743-3A-DAJ.
Compatibility & Miscibility
Miscibility
Shell Corena S4 R ISO VG 68 oils are fully miscible with mineral oils, although dilution with mineral lubricants will markedly reduce its performance. Care must be taken to avoid mixing Shell Corena S4 R with certain other types of synthetic fluids.
Seal Compatibility
Shell Corena S4 R 68 oils are compatible with seal materials specified for use with mineral oils.
