Product Descr1ption
Mobil DTE 790 Series oils are premium quality lubricants intended for use in critical steam turbine systems where superior oxidation stability is required and where oil color stability can be critical factor in assessing oil life. They are formulated from very high quality, hydrotreated base oils and a zinc-free additive system which provide exceptional chemical stability, cleanliness and outstanding protection against oxidation, rust and corrosion. Increased protection against wear is provided, ensuring that a tenacious lubricating film is maintained, even during turbine start-up and shut-down. Demulsibility characteristics are excellent, giving rapid separation of water. The oils have low foaming tendency. Mobil DTE 790 Series oils, in appropriate viscosity grades, meet or exceed the requirements of ABB-Stal VTI 3800-3, ABB/BBC HTGD 90117E, GEC-Alsthom NBA P50001, Siemens-KWU TLV9013 04/01, and all major gas and steam turbine builders. In addition, Mobil DTE 797 passed the Anti-Ammoria Test according to the Chinese petrochemical industrial standard SH/T0302.
Benefits
