Teresstic GTC 32
Premium Turbine Oil
Product Description
Teresstic GTC 32 is the brand name for a super-premium long-service-life turbine oil developed specifically to address the unique problems associated with turbines that operate in cyclic, or peak-load-leveling, service in high-temperature environments.
Certain turbines, both gas and steam, are in non-base-load service in which frequent stops and starts can create an unstable temperature environment that promotes the formation of oxidation by-products, which in turn can plug filters and cause erratic operation of close-tolerance servo valves. Teresstic GTC 32 has been formulated to reduce formation of oxidation by-products and to protect against those that do form.
Features and Benefits
- Provides clean, dependable lubrication for extended service periods
- Oxidation life significantly greater than that of conventional turbine oils
- Exceptional cleanliness per the ASTM D 4310 Sludging and Corrosion Control Test
- Fortified with oxidation, rust and foam inhibitors
- Incorporates technology that has been proven in millions of hours of excellent field service in the demanding high-temperature environments of GE Frame 7 and 9 turbines
Applications
Teresstic GTC 32 is the primary recommendation for applications that involve cyclic gas turbine operation. It is recommended by ExxonMobil for applications requiring General Electric's severe GEK-32568F standard, as well as DIN 51515 Parts 1and2, and DIN 51524 Part 1.
