Designed to Meet The Challenges

Long oil life – Maintenance saving – shell Corena S4 R is capable of providing oil maintenance intervals of up to 12,000 hours (where allowed by manufacturers) even when operating at maximum discharge temperatures in excess of 1000C. The advanced formulation of Shell Corena S4 R helps deliver exceptional oil life through:

• Exceptional resistance to thermal and chemical breakdown.
•  Resist formation of deposits on rotating components in screw compressors and in sliding vane slots for continuous efficient operation.
• Exceptionally low levels of deposit formation to help maintain excellent internal surface cleanliness particularly in oil/air separator and coalescer systems.

Outstanding wear protection:

• Shell Corena S4 R is designed to provide rapid air release without excessive foaming to give trouble-free operation even under cycling conditions helping to ensure reliable start-up and continuous compressed air availability. .
• Shell Corena S4 R has low volatility and oil carryover to provide reduced oil top-up requirements in combination with increased air quality.

Maintaining system efficiency:

Designed to provide rapid air release without excessive foaming to give trouble-free operation even under cycling conditions helping to ensure reliable start-up and continuous compressed air availability. Low volatility and oil carryover to provide reduced oil top-up requirements in combination with increased air quality. In addition, excellent water separation properties help ensure continuous efficient operation of the compressor even in the presence of water.

Main Applications

• Rotary sliding vane and screw air compressors
  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 1000C
  (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
  The product is recommended for use in ABB turbochargers fitted to low and medium speed diesel engines used in marine and power generation applications.
