eni OTE GT

eni OTE GT are superior quality lubricants developed expressly for use in industrial gas turbines. They are formulated utilising highly refined group III base stocks with the latest technology additive to obtain an exceptional resistance to oxidation and antirust and mild EP properties.

PROPERTIES AND PERFORMANCE

  • The eni OTE GT contain additives with exceptional anti-oxidant properties that reduce oil ageing and avoid formation of sludges and deposits; this is illustrated by its performance in TOST test (Turbine Oil Stability Test), where it exceeds 10000 hours.
  • The high viscosity index of eni OTE GT oils minimizes changes in viscosity throughout the normal temperature range, thus ensuring that a proper lubricant film is maintained even at high operating temperatures.
  • The anticorrosion and antirust properties provide effective protection of all lubricated parts, the oil circuit, storage tanks, heat exchangers, etc.
  • The eni OTE GT have very good antifoam properties; they readily eliminate entrained air thus reducing the danger of discontinuity in the lubricating film, air locks and cavitation in the circulation, erratic regulator operation and overflow of oil from storage tank vents.
  • The demulsibility properties prevent formation of stable emulsions, ensuring complete water separation in the oil. This characteristic is particularly appreciated in combined-cycle plants where only one high-performance product need be used to serve both gas and steam turbine lubrication requirements.
  • They have mild EP properties which are essential for ensuring long life of turbine reduction gear units, as illustrated by typical test results: eni OTE 32 GT have a FZG failure load stage of 12Th.

 

APPLICATIONS
The eni OTE GT are essentially intended for the lubrication of gas turbines with bearings whose operating temperatures are around 500°F (260°C). They are also suitable for lubrication of steam turbines in the combined-cycle plants and also in those cases where at the turbine is associated a reduction gear
