Advanced Synthetic Technology Platforms:
Shell Corena S4 utilizes cutting-edge synthetic base oil technology to deliver exceptional performance across diverse compressor applications. Both product ranges can be recognized by either the letter R or P. You will also recognize the S4 which identifies the fully synthetic range with high performances.
Three High-Performance Variants:
Shell Corena S4 P 100 - An advanced synthetic air compressor oil incorporating synthetic ester base fluids and a unique high performance additive system. It is designed to deliver the highest performance lubrication for high pressure reciprocating compressors running in excess of 220°C discharge temperatures at elevated pressures.
Shell Corena S4 R 46 - Shell Corena S4 R46 is primarily an advanced synthetic air compressor oil designed to deliver the highest performance lubrication of rotary sliding vane and screw air compressors. It uses a unique advanced additive system to provide excellent protection and performance for compressors running with oil maintenance intervals of 10,000 hours and up to 12,000 hours under certain conditions.
Shell Corena S4 R 68 - 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 100°C discharge temperatures with oil maintenance intervals of up to 12,000 hours.
Revolutionary Performance Benefits:
- Extended Oil Life - Shell Corena S4 R is capable of providing oil maintenance intervals of 10,000 hours (where allowed by manufacturers) even when operating at maximum discharge temperatures in excess of 100°C. This may enable you to match oil life to your operational needs
- Exceptional Thermal Stability - Shell Corena S4 P is designed to deliver the highest performance lubrication for high pressure reciprocating compressors running in excess of 220°C discharge temperatures at elevated pressures
- Superior Wear Protection - Shell Corena S4 R helps provide exceptional protection of internal metal surfaces from corrosion and wear. Advanced additive system provides excellent protection for critical components
- Outstanding Deposit Control - Exceptionally low levels of deposit formation to help maintain excellent internal surface cleanliness particularly in oil/air separator and coalescer systems
Advanced System Efficiency:
- Excellent Water Separation - Shell Corena S4 R 68 ensures an excellent water-separating ability to ensure continuous efficient compressor operation, even in the presence of water
- Superior Air Release - Excellent air separation and minimum foaming ensures optimal compressor operation and air quality
- Low Volatility - Shell Corena S4 R 68 also has low volatility, leading to lower evaporation and oil transfer in the compressor, reducing oil refills less frequently, combined with increased air quality
- Enhanced Temperature Performance - Improved low temperature fluidity, and lowering equipment operating temperatures through advanced synthetic formulation
Specialized Applications:
- Reciprocating Air Compressors - Shell Corena S4 P 100 is suitable for use in industrial reciprocating air compressors operating with air discharge temperatures in excess of 220°C
- Rotary Screw Compressors - Shell Corena S4 R 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 100°C
- Rotary Sliding Vane Compressors - Designed specifically for rotary sliding vane and screw air compressors under severe operating conditions
- Bearing & Circulating Applications - Perfectly suitable to cover applications where a synthetic bearing & circulating oil or R&O oil (ISO VG 32-68) is required
- Breathing Air Compressors - Shell Corena S4 P may be used in breathing air compressors, provided subsidiary clean-up apparatus is used to ensure that the air produced is fit for breathing
- Severe Service Conditions - May also be used where exceptionally high ambient temperatures are found, when the oil temperature cannot be reduced to normal levels
Industry-Leading Approvals:
Comprehensive approvals including ISO 6743-3A-DAJ, BS EN 12021, DIN 51506 VDL, and Shell Corena S4 R 68 is approved by ABB for use in VTR turbochargers, with a maximum oil change interval of 5,000 hours, ensuring compatibility with the most demanding industrial equipment.
Why Choose Shell Corena S4 Synthetic:
Modern compressor operations demand synthetic oils that deliver exceptional performance under extreme conditions while maximizing equipment uptime and minimizing total cost of ownership. Shell Corena S4 provides the complete solution - advanced synthetic technology that significantly exceeds conventional mineral oil performance.
Proven Synthetic Advantage:
Shell Corena S4 R 68 has 1.5x longer oil life than Corena S3 R with no deposits at high operating temperatures. The advanced formulation helps deliver exceptional oil life through exceptional resistance to thermal and chemical breakdown, resisting formation of deposits on rotating components.
Technical Excellence:
Shell Corena S4 P is a high-quality synthetic oil composed of synthetic esters and unique high-quality additives. Shell Corena S4 R incorporates a unique high performance additive system designed to deliver the highest performance lubrication for demanding compressor applications.
Breathing Air Applications:
Shell Corena Oil should only be used in breathing air applications that are fitted with appropriate filtration systems to suit the Grade of air to be produced. Approvals include BS EN 12021 for breathing air applications with proper filtration systems.
Compatibility Considerations:
Shell Corena S4 R 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.
Maintenance Excellence:
The longer an oil's life, the less fluid maintenance your equipment requires, so it can continue to operate without interruption. From mainstream oils for standard life applications to advanced synthetic oils that can last for up to three years, the Shell Corena range enables you to choose the right oil for your needs.
Operational Reliability:
Rigorous competitor evaluation has proven that Shell Corena oils are the best overall choice for ensuring reliable air supply. Shell Corena S4 scores strongly on all performance criteria including oil life, anti-wear protection, antifoaming properties, and water-shedding capability.
