Turbine Oils

Apar power turbo grades are premium quality turbine oils made from paraffnic base stocks having excellent oxidation and thermal stability. These properties are further enhanced by selected additives. Turbine lube oil systems have many missions. Among the most important: cooling bearings, flushing contaminants away from rotating parts, providing hydrostatic lift for shafts, actuating valves in the hydraulic circuit, and coating and lubricating the system internals. Formulating lubricants capable of performing all these tasks well is a difficult job, one that must consider the impacts of large temperature fluctuations and ingress of contaminants such as dirt and water, as well as other physical and chemical challenges. With time since the specifications set by turbine manufacturers have been amended with the changes in design, turbine oils have undergone several advancements. Turbine oils must now simultaneously meet the requirements of both steam and gas turbines. Improvements in base oil refining technologies provide more thermally stable and oxidatively robust products. Coupled with improvements in additive chemistries, modern turbine oils represent a delicate blend of lubrication science.
