Shell Corena S4 R 68

Shell Corena S4 R 68 applications are:

The excellent properties of Shell Corena S4 R 68 are especially effective in the heaviest loaded compressors that operate at a pressure of 25 bar or a compression temperature of 100 C. Shell Corena S4 R 68 can also be used for bearing lubrication at high temperatures, such as in turbochargers.
 

Rotary sliding vane and screw air compressors

Shell Corena S4 R 68 is suitable for oil-immersed /oil-based oiled or two-stage palettes or screw air compresses

Heavy operating conditions

Can also be used where the ambient temperature is exceptionally high or humid.

Oil for bearing and circulation system

Excellent for lubrication of systems requiring a synthetic bearing and circulation oil of the type "R & O" (ISO VG 32-68) and benefits from increased resistance to deposit build-up, improved fluidity at low temperature and lower operating temperatures.

Shell Corena S4 R 68 Performance, Features & Advantages:

• + Extended life and savings on maintenance
• + Exceptional protection against wear
• + Preservation of system efficiency 
  

Explanation Performance, Features & Benefits Shell Corena S4 R 68

+ Extended service life and maintenance savings

Shell Corena S4 R 68 can offer oil change intervals up to 10,000 hours (if allowed by manufacturers) even at maximum discharge temperatures above 100C. This can be extended to 12,000 hours under certain conditions. The advanced formulation of Shell Corena S4 R 68 achieves exceptional oil life thanks to:

• Exceptional resistance to chemical and thermal degradation.
• Resist the formation of deposits on rotating components in screw compressors for continuous efficient operation.
• Exceptional resistance to a build-up of deposits which helps to maintain a very high cleanliness of internal surfaces, especially in oil /air separator and coalescence filter systems.

The maintenance interval depends on the quality of the let-in air, operating and environmental conditions. For hot and humid climates as they occur in the regions Asia & the Pacific, a shorter oil change period of 10,000 hours is recommended

+ Exceptional protection against wear

Shell Corena S4 R 68 provides excellent protection for internal metal surfaces against corrosion and wear. It includes an advanced shaftless anti-wear system that extends the life of critical parts such as bearings and gears.

+ Preservation of system efficiency

Shell Corena S4 R 68 provides fast air separation without excessive foaming for efficient operation, even under severe operating conditions, for a reliable start and continuous operation. to ensure the availability of compressed air. 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. Shell Corena S4 R 68 also ensures an excellent water-separating ability to ensure continuous efficient compressor operation, even in the presence of water.

+ Miscibility

Shell Corena S4 R 68 oils are fully miscible with mineral oils, but mixing with these lubricants will significantly reduce performance. Shell Corena S4 R 68 should not be mixed with certain other types of synthetic fluids.

+ Compatibility with seals

Shell Corena S4 R 68 Oils are compatible with specified elastomers for use with mineral oils.

Specifications, Approvals & Recommendations Shell Corena S4 R 68

ISO 6743-3: 2003 (E) L-DAJ Shell Corena S4 R 68 is approved by ABB for use in VTR turbochargers, with a maximum oil change interval of 5,000 hours.
