  • Reciprocating compressors having separate cylinder lubrication systems
  • Compression of wet air, wet hydrocarbon, natural gas or certain chemically active gases
  • Use for pressures below 1000 psi
  • Bearings and machine parts of equipment requiring compounded products
  • This oil should not be used to lubricate the running gear or crankcases of compressors as the fatty oil can separate from the lubricant, forming deposits on the surfaces of the crankcase and plugging oil passages.
Features and Benefits N/A Long Oil Life - Maintenance Saving - Shell Corena S2 P 100 allows the interval between valve and piston maintenance to be extended under certain applications. Compressors can be kept in service for much longer periods, operating at a consistently high level of efficiency. Extended maintenance capability is supported by resistance to formation of carbon deposits and lacquer on valves and piston crowns at high working temperatures and pressures. 

Outstanding Wear Protection - Shell Corena S2 P 100 helps provide effective protection of internal metal surfaces from corrosion and wear to help prolong the life of critical parts such as bearings and pistons. 

Maintaining System Efficiency - Shell Corena S2 P 100 helps prevent the formation of carbon deposits and lacquer on valves and piston crowns at high working temperatures and pressures. These can cause serious damage, lower compressor efficiency and increase maintenance costs. In addition, Shell Corena S2 P 100 has good water separation to help prevent accelerated corrosion, facilitating easy condensate draining.

Enhanced Air Line Safety - In discharge air-lines, the combination of rust particles, dispersed in carbonaceous deposits, coupled with heat from recently compressed air, can cause a reaction leading to the possibility of fires and explosion. Shell Corena S2 P 100 helps to minimize the likelihood of the danger.

 		N/A Long Oil Life - Maintenance Saving - Shell Corena S4 P 100 is designed to provide safe, reliable and effective lubrication for extended service periods where mineral compressor lubricants are unsatisfactory. With an extremely low tendency for deposit build-up, Shell Corena S4 P 100 helps ensure continued high performance of the compressor over long periods and reduces maintenance costs and shutdowns. Shell Corena S4 P 100 can extend the normal valve maintenance period from typically up to 1000 hours of operation using conventional mineral oils, to 2000 to 4000 hours depending on operating conditions.

Outstanding Wear Protection - Shell Corena S4 P 100 helps provide exceptional protection of internal metal surfaces from corrosion and wear to help prolong the life of critical parts such as bearings and gears.
