Shell Corena S4 R
Advanced Synthetic Rotary Air Compressor Oil
Shell Corena S4 R is 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 100o
C discharge temperatures with oil maintenance intervals of up to
12,000 hours.
Performance Benefits
? 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
100oC.
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.
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, a reduced oil drain period is
recommended (consult OEM recommendations).
? Outstanding wear protection
Shell Corena S4 R helps provide exceptional
protection and 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
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.
In addition, Shell Corena S4 R has excellent
water separation properties to help ensure
continuous efficient operation of the compressor
even in the presence of water.
Applications
? Rotary sliding vane and screw air compressors
Shell Corena S4 R is suitable for oil-flooded/oilinjected, single or two-stage compressors,
operating at pressures of in excess of 25 bar and
with air discharge temperatures of over 100°C
(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.
? EXTRA LONG LIFE
? IMPROVED EFFICIENCY
? SEVERE APPLICATIONS
