Teresstic GT

Turbine Oil

Product Description

Teresstic GT is a high-quality turbine oil formulated to provide effective day-in and day-out performance of steam turbine and gas turbine electricity generators and mechanical drive systems. Teresstic GT is available in two ISO grades, 32 and 46.

Features and Benefits

The advanced, non-volatile additive formulation in Teresstic GT provides exceptionally long service life. Its excellent oxidation resistance minimizes sludge and varnish formation to maintain oil cleanliness. With Teresstic GT, oil conditioning needs are less critical and the need for reinhibition in severe-service applications is much less frequent.

Teresstic GT offers excellent water separation, anti-foam and low air entrainment qualities to make a high rate of oil circulation possible. Its long-lasting rust controlling additives ensure the protection of critical oil system components. Its optimum viscosity, combined with high oil flow, allows maximum heat removal from bearings, while consuming less energy in internal friction and pumping losses. Teresstic GT helps protect high-performance equipment configurations, providing the necessary lubricant film strength to help prevent premature wear and bearing failures.

Applications

Teresstic GT is appropriate for a wide range of turbine applications, such as steam and gas turbines, compressors and pumps, including piston hydraulic pumps. It is an excellent multi-purpose lubricant.
