NATIONAL TURBINE OIL T

    National Turbine Oil T are high-quality inhibited Zinc Free oils. They are formulated from premium quality, chemically stable, high VI base stocks, which are further enhanced by the addition of oxidation inhibitors. These inhibitors provide resistance to thermal degradation over long periods of time in the presence of entrained air and catalyzing metals. National Turbine Oils T/R exhibit good demulsibility, permitting water and other contaminants to readily separate from the oil in the system reservoir.

    Benefits

    • Excellent water separation.
    • Very high oxidation stability.
    • Long service life.
    • Effective anti-foam properties.

    Applications

    National Turbine Oil T are suitable for use in water and steam turbines bearing lubrication and cooling which require mineral turbine oils. In addition, National Turbine Oil T promotes outstanding performance in hydraulic systems, gear cases, bearing and other industrial units.
