RENOLIN ETERNA turbine oils were developed for gas, steam, and expansion turbines as well as for turbo compressors with and without gearboxes based on the latest lubrication technology.
The excellent properties of the hydro-finished Group-III base oils produced in a special process are enhanced using a carefully selected additive system. RENOLIN ETERNA oils contain no metal-organic compounds and are therefore ashless. They provide a zinc-free wear protection.
RENOLIN ETERNA is especially suited for use in turbine systems with a common control and lubricating oil circuit. It can also be used as a bearing and sealing oil in hydrogen-cooled generators.
• High thermal stability • Rapid air release • No foaming • Low pour point • Good wear protection • Good viscosity-temperature behaviour • Good water separation behavior • Excellent corrosion protectionSpecifications RENOLIN ETERNA 46 are approved by Siemens Power Generation
