Cirro 20K Turbine Oil

Product Description:

turbineCirro 20K Turbine Oil is a superior quality rust and oxidation inhibited turbine oil designed for use in both steam and gas turbines. The ASTM D-943 TOST result more than 16,000 hours enables it to be used in applications which require very long life where other turbine oils fail. It is recommended for use in steam and gas turbines, including the General Electric Frame 7 units, as well as many pumps, compressors, oil circulating systems, centralized oil mist systems and other applications requiring a supreme quality, long life turbine oil.


Cirro 20K Turbine Oil meets or exceeds most pump manufacturer’s specifications and may be used as a premium hydraulic fluid, compressor oil, and other applications as recommended where superior performance of an R&O type fluid may be needed. These high performance circulating lubricants are designed for applications where long lubricant service life is required. Specific applications include:

  • Land-based and marine steam turbine, hydro turbine and some gas turbine circulation systems, including pumps, valves and other ancillary equipment
  • Continuous service in plain and roller bearings and parallel shaft gearing.
  • Turbines with oil supplied by splash, bath, ring oiling or other mechanical means.
  • Moderate severity hydraulic pumps.
  • Compressors and vacuum pumps handling air, natural gas, and inert gases, and with discharge temperatures not exceeding 150 degrees C.

Key Features :

  • Versatile – Can be used in multiple applications requiring a superior quality non-EP (zinc free) oil with excellent oxidation resistance.

Customer Benefits:

  • Extended Drain – Outstanding oxidation resistance enables extended oil drain intervals, with significantly reduced sludge, varnish and carbon deposits on exhaust valves and other compressor components, considerably reducing the necessity for valve cleaning and other maintenance.

Packaging Options:
Totes, Drums and Pails
