Premium Gas, Steam and CCGT Turbine Oil
Teresso™ GTC Series Turbine Oils are high performance turbine oils designed to provide excellent lubrication for turbines in the most severe operating conditions. Teresso GTC provides high performance and flexibility, as it can be used in steam, gas, and combined cycle gas turbine (CCGT) applications. Teresso GTC is formulated with carefully chosen, high quality hydrotreated basestocks and a proprietary additive package, that work synergistically to provide worry free, high performance and long service life in turbine applications. TERESSO GTC has shown exceptional trouble-free long-life performance in severe cyclical service gas turbines.
Teresso GTC provides long service life that can be measured over time by monitoring its RPVOT ASTM D2272 (Rotary Pressure Vessel Oxidation Test) performance. RPVOT retention in high temperature, severe service lube systems is a key indicator of the lubricant’s condition and remaining oxidation performance. Teresso GTC has a very high initial RPVOT value and excellent in-service RPVOT retention that enables its potent capability to delivering long service life and “keep clean” performance in turbine lubrication systems.
Varnish and deposit control and “Keep Clean” performance in severe duty gas turbines are key features of Teresso GTC. Lower quality turbine oils can form degraded materials such as varnish, early on in their service life. These degraded materials can dirty up a system, plug up tight tolerance valves and filters and cause unexpected outages. All of these problems can lead to high cost operations, increased maintenance and costly failures to deliver power when required. Teresso GTC is formulated to deliver cleanliness and oxidation control and keep the lube system clean and running reliably.
Teresso GTC provides excellent demulsibility results and rapid water separation, which are critical to steam and gas turbine operations. Teresso GTC’s formulation also includes a thermally stable non-zinc antiwear system that provides the load carrying requirements of many geared turbines and other ancillary equipment in the power plant. Powerful foam control, excellent air release, rust and corrosion protection and good low temperature performance round out the excellent service capabilities of this high performance lubricant.
Teresso GTC 32 is recommended for certain steam and gas, non-geared and geared turbines manufactured by Alstom, (ABB) HTGD, GE (GEK- 32568) and (GEK-101941A), Solar (ES 9-224), Siemens (TLV 9013 04), Westinghouse and Hitachi.
