DESCRIPTION Servopress oils are air compressor lubricants specially developed to minimise the incidence of fire and explosions in modern air compressors. These oils provide satisfactory lubrication under prolonged high temperature and load conditions, since they are exceptionally stable and are incorporated with antioxidant and rust inhibitor additives. PERFORMANCE STANDARDS Servopress oils meet the following specifications: • ISO DIS – 6521 • DIN – 51506, VD-L MANUFACTURERS APPROVAL Servopress oils are approved by: • AtlasCopco (India) Ltd., Pune • K. G. Khosla Compressors (Pvt.) Ltd., Faridabad


APPLICATION Servopress oils are suitable, not only for cylinder lubrication of high performance, portable and stationary reciprocating units, but also for rotary compressors. Servopress oils are recommended for air compressor lubrication with air discharge temperatureupto 220°C

 PERFORMANCE BENEFITS • Provide excellent resistance to oxidation, thus permitting extended oil drain intervals • Minimise carbon deposits on the valve plates thereby reducing risk of fire and explosion • Enable trouble free starting at low temperatures • Provide effective protection against rust and corrosion during routine shut down • Reduce oil consumption. • Reduce maintenance cost, due tominimum carbonisation, resulting in optimum valve service life and longer overhaul intervals 

Customers looking for longer oil life, better protection and system efficiency in Tier 4 or 5 should choose Shell Corena S4 R or Shell Corena S5 R based on their application (polyalphaolefin or polyalkylene glycol) and equipment specifications.

EVERY PART OF YOUR MACHINE OR PROCESS HAS BEEN METICULOUSLY ENGINEERED, SO YOU WANT TO BE SURE THAT YOU CHOOSE A LUBRICANT THAT HAS BEEN DESIGNED TO ENSURE THAT YOUR EQUIPMENT IS WELL PROTECTED AND WORKS EFFICIENTLY.
The Shell Corena range of air compressor oils has been developed to enable equipment operators to select the oil that will deliver optimum value to their operations through enhanced wear protection, long oil life and high system efficiency

SHELL CORENA MAKES IT POSSIBLE Shell Corena air compressor oils enable equipment operators to select the oil that will help to deliver optimum value to their operations through enhanced wear protection, long oil life and high system efficiency
REAL-WORLD VALUE DELIVERY Customers that have switched to Shell Corena S4 R have seen the following benefits n 100% longer oil-drain intervals compared with conventional oils n extended equipment service life: one cement company is running its compressors for three times longer between overhauls n a reduction in the high operating temperatures caused by thickening of the original oil, which prevented the oil valves from working efficiently. n increasing oil-drain intervals by 100% compared with conventional oils n extending equipment service life: one cement company is running its compressors for three times longer between overhauls n reducing the high operating temperatures caused by thickening of the original oil, which prevented the oil valves from working efficiently 
WEAR PROTECTION The Shell Corena range includes dedicated rotary compressor oils designed to control vane and screw wear, and oils for reciprocating compressors specifically to control cylinder, piston-ring and valve wear. The range incorporates the latest synthetic oils – Shell Corena S5 R, Shell Corena S4 R and Shell Corena S3 RX – for enhanced wear protection in high-temperature conditions and for extended operations

Shell Corena S5 R is compatible with leading equipment manufacturers’ polyalkylene glycol compressor fluid such as Ingersoll-Rand Ultra Coolant and Sullair Sullube. Customers who wish to change from a mineral or polyalphaolefin-based compressor oil such as Shell Corena S4 to polyalkylene glycol-based Shell Corena S5 R will need to follow the correct change-over procedures. However, it is unlikely that such a changeover would be required because, if a polyalkylene glycol oil is specified, this will have been used from the start of operation.

HPCL SEETUL S 68 are fully synthetic lubricants, designed for use in refrigeration compressors and heat pumps. They are formulated from polyalphaolefin (PAO) fluids, which have outstanding resistance to thermal/oxidative degradation. Their naturally high shear stable viscosity index and low temperature fluidity, make them perform in severe service conditions that are beyond the capabilities of conventional mineral oils.

Their solubility and miscibility with refrigerants is low, resulting in higher film thickness in the presence of refrigerants under pressure and reduced shaft seal leakage. Their stability and low volatility eliminates “light end stripping” which can occur with conventional mineral oils.
