TotalEnergies Preslia GT 32

The very high-performance mineral oil TotalEnergies Preslia GT 32 is specially formulated for the lubrication and protection of gas turbines, steam turbines, and combined cycle systems operating under demanding thermal and mechanical conditions.

TotalEnergies Preslia GT 32

Technical Features

• Type: High-performance oil for industrial gas, steam, and combined cycle turbines.

• Viscosity Grade: ISO VG 32.

• Thermal Stability and Oxidation Resistance: Exceptional resistance to thermal aging and degradation, minimizing the formation of deposits, sludge, and varnish at high operating temperatures.

• Anti-wear and Extreme Pressure (EP) Protection: Formulation reinforced with anti-wear and EP additives to protect highly loaded gearboxes coupled to the turbine.

• Varnish Control: Reduced tendency for lacquer and varnish formation in control valves and hydraulic servomechanisms.

• Excellent Demulsibility and Air Release: Rapid water separation and efficient deaeration prevent cavitation and ensure the continuity of the lubricant film.

• Corrosion Protection: Provides superior protection against rust and corrosion in the presence of water or moisture.
