Shell EcoSafe Turbine Fluid S5 X 25/32
- Top-tier gas and combined-cycle turbine fluid
- Delivers strong protection against fluid breakdown, even under conditions of high oxidation and thermal stress
- Can help extend service life and reduces maintenance costs compared to mineral-based turbine products
- Uses inherently oxidatively-stable base fluids that are formulated with a balance additive package, which provides high-resistance to oxidative degradation and the formation of corrosive species, deposits, and sludge
- The fluid enables rapid air-release and is formulated with an anti-foam additive to help prevent pump cavitation, excessive wear, and premature fluid oxidation
- Compatible with commonly used seals, hoses, and metals
- Meets General Electric’s PAG Non-Varnishing specifications for GEK 32568K
Shell EcoSafe Turbine Fluid S5 GX 25
- Top-tier gas and combined-cycle turbine fluid for geared turbines
- Provides exceptional protection against fluid breakdown, even under conditions of high oxidation and thermal stress
- The fluid’s excellent resistance to varnish and sludge formation helps to reduce the wear of critical system components and prevent unplanned turbine outages due to valve sticking
- Offers enhanced anti-wear protection for heavily loaded gearboxes
- Meets General Electric’s PAG Non-Varnishing specifications for GEK 32568K
