Applications

Applications

 N/A Power and Industrail Steam, Gas, & Combined Cycle Turbines - Shell Turbo S4 GX 46 is used as the lubricating oil of choice in modern steam, gas, and combined cycle turbines, especially those needing enhanced anti-wear performance to protect highly loaded gearboxes.

Further Industrial Applications - Shell Turbo S4 GX 46 may also be used for other industrial applications requiring a high performance gas turbine oil, such as the lubrication of turbo compressors.

Features and Benefits

Features and Benefits

 N/A Extended Oil Life - Shell Turbo S4 GX 46 delivers exceptional resistance to degradation, even under conditions of high oxidative and thermal stress. Excellent results in both the ASTM dry TOST and the TOST life test (ASTM D943) demonstrate the potential for Shell Turbo S4 GX 46 to offer extended service life, reduced maintenance costs and less downtime when compared to conventional mineral oil technology.

Enhanced Equipment Protection - The excellent prevention of deposit formation provided by Shell Turbo S4 GX 46 enables it to lubricate the hottest gas turbine bearings with minimal deposit build up or sludge formation. This reduces the potential for critical component failure and the risk of unplanned turbine shutdown. As the pressure increases on gearboxes in turbines it is critical for an oil to provide greater anti-wear protection. Shell Turbo S4 GX 46 offers enhanced anti-wear protection for heavily loaded gear boxes helping end users maintain optimum operating conditions under challenging situations without sacrificing resistance to deposits or oil life.

Enhanced System Efficiency - Demulsibility, air release, resistance to foaming, and filter blockage are critical factors for oil in the latest geared turbine designs (especially turbines which have shorter oil residence times). Shell Turbo S4 GX 46 offers excellent performance in all four areas, ensuring that optimum operating conditions are maintained.
