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.
