Mobil DTE 746
Mobil DTE 746 is a high-performance turbine lubricant engineered for use in gas and steam turbine applications where reliability and long oil life are critical. Formulated with carefully selected base oils and advanced additives, including antioxidants, rust and corrosion inhibitors and anti-foam agents, it delivers consistent performance under demanding operating conditions. The zinc-free formulation also supports reduced environmental impact while maintaining excellent equipment protection.
One of the key advantages of Mobil DTE 746 is its exceptional oxidation and chemical stability. The formulation resists degradation over extended operating periods, helping reduce deposit formation and maintain clean turbine systems. This contributes to improved reliability, reduced maintenance and extended oil service life.
Mobil DTE 746 also provides excellent water separation characteristics. The oil rapidly separates from water, helping maintain effective lubrication and supporting efficient water removal. This reduces the risk of corrosion and helps protect turbine bearings and system components.
Another important benefit of Mobil DTE 746 is its strong rust and corrosion protection. It helps safeguard critical system components from moisture-related damage, ensuring long-term durability and reduced maintenance costs.
Mobil DTE 746 also offers excellent air release and anti-foaming performance. These properties help prevent aeration and cavitation, ensuring stable hydraulic control and smooth turbine operation. This contributes to improved system efficiency and reduced equipment wear.
Mobil DTE 746 is recommended for use in steam and gas turbines in power generation, combined cycle plants and industrial applications. It is also suitable for hydroelectric turbine systems and other circulation systems where high-quality turbine oil performance is required.
Physical characteristics include a kinematic viscosity of approximately 44.1 mm²/s at 40°C and 6.9 mm²/s at 100°C, with a viscosity index of around 113. Mobil DTE 746 has a density of approximately 0.86 g/cm³ at 15°C, a flash point of approximately 242°C and a pour point of approximately −21°C, supporting reliable performance across a wide range of operating conditions.
