Shell Corena Compressor Oils

• Long Life
• Improved Efficiency

Previous Name: Shell Corena S

• Long oil life – Maintenance saving
  Shell Corena S3 R is capable of providing oil maintenance intervals of 4,000 hours (where allowed by manufacturers) even when operating at maximum discharge temperatures of up to 1000C. This may be extended to up to 6,000 hours under certain conditions.
  It is formulated to help:
• Resist formation of carbon deposits in sliding vane slots in vane compressors
• Resist formation of deposits on rotating components in
  screw compressors
• Resist thermal breakdown and deposit formation to maintain excellent internal surface cleanliness particularly
  in oil/air separator and coalescer systems.
• The exact oil maintenance interval will depend on intake air quality, duty cycle and ambient conditions. For hot and
  humid type climates as found in the Asian and Pacific regions, the lower oil drain period of 4,000hrs is recommended (also consult OEM recommendations).
• Outstanding wear protection
  With many years of successful application, Shell Corena S3 R helps provide effective protection of internal metal surfaces from corrosion and wear.
  It contains an advanced ashless anti-wear system to help prolong the life of critical parts such as bearings and gears.
• Maintaining system efficiency
  Air release and prevention of foaming are critical performance characteristics in a compressor oil, ensuring reliable start-up and continuous compressed air availability. Shell Corena S3 R is designed to provide rapid air release without excessive foaming to give trouble-free operation even under cycling conditions.
  In addition, Shell Corena S3 R has excellent water separation properties to help ensure continuous efficient operation of the compressor even in the presence of water.

The Shell Corena range of air compressor oils has been developed  to enable equipment operators to select the oil designed to deliver  optimum value to their operations through enhanced wear protection,  long oil life and high system efficiency.

Wear Protection:
Excess wear can seriously compromise an air compressor’s life  and efficiency. The Shell Corena range includes dedicated rotary  compressor oils designed to control vane and screw wear, and  oils for reciprocating compressors specifically to help control  cylinder, piston-ring and valve wear. Whatever your technical needs and operational conditions, there  is a Shell oil that is designed to help you get the most from your  equipment investment. The Shell Corena range includes the latest  synthetic oils for enhanced wear protection in high-temperature  conditions and for extended operations.

Oil Life:
The longer an oil’s life, the less fluid maintenance your equipment  requires, so it can continue to operate with less interruption. The  Shell Corena range enables you to best match oil life to your  operational needs. 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 need.

System Efficiency:
Pressure loss in worn compressors can reduce operational  efficiency and increase costs. Shell Corena oils are designed  to promote system efficiency by suppressing foaming, releasing  trapped air and rapidly separating out condensed water. The oils  are also developed to help to reduce wear, which helps to keep  your compressors working as their designers intended.
