Manufacturer's description

Premium based industrial steam, gas and combined cycle turbine lubricant for geared turbines. Shell Turbo S4 GX 32 is based on Gas-to-Liquid (GTL) technology and has been developed to meet the demands of the latest high efficiency turbine systems. Designed to offer outstanding, long term performance under the most severe operating conditions Shell Turbo S4 GX 32 will minimise wear, deposit and sludge formation even under cyclic peak loading conditions.

Applications

  • Power and industrial steam, gas & combined cycle turbinesShell Turbo S4 GX 32 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 applicationsShell Turbo S4 GX 32 may also be used for other industrial applications requiring a high performance gas turbine oil, such as the lubrication of turbo compressors
  • Turbo S4 GX 32

Performance & benefits

  • Extended oil lifeShell Turbo S4 GX 32 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 32 to offer extended service life, reduced maintenance costs and less downtime when compared to conventional mineral oil technology.
  • Enhanced Equipment protectionThe excellent prevention of deposit formation provided by Shell Turbo S4 GX 32 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 32 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 EfficiencyDemulsibility, 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 32 offers excellent performance in all four areas, ensuring that optimum operating conditions are maintained.
