Turbine Oils & Specialty Fluids

Turbine oils for steam and gas turbines, plus a range of specialty synthetics for unique OEM requirements.

Quick Answer

Castrol Perfecto T (mineral turbine oils) and Alphasyn T (synthetic turbine oils) for steam turbines, gas turbines, hydro turbines and compressor turbo-machinery. R&O grades for non-EP service; EP-modified grades for geared turbines with reduction gears. Long-life operation, with oxidation stability high enough that the charge is managed on condition rather than replaced to a calendar. Specifications include British Standard BS 489 and DIN 51515 compliance.

Frequently Asked Questions

Why does steam-turbine oil last 20+ years in service?

Because operating temperatures are modest (50–70°C in the reservoir), oxidation proceeds very slowly. The governing factor is varnish accumulation and water contamination, not oxidation. Regular patch-testing (MPC) and kidney-loop filtration keep a good turbine oil in spec for decades.
