TURBINE OIL T Series
 

Description

PSO Turbine Oil T-series is blended with highly refined hydrofinished base oils having excellent oxidation stability which is further enhanced with advance additive component technology to provide superior performance and protection against corrosion and rust of ferrous and non-ferrous metals. PSO Turbine Oil T-series exhibit excellent oxidation and thermal stability with extended service life of steam and gas turbine.
 

Applications

  • PSO Turbine Oil T-series oils are primarily intended for the lubrication of steam turbines, base oils are selected to give the requisite water separation characteristics, resistance to foaming and inherently excellent air release properties essential for this demanding application.
  • PSO Turbine Oil T-series oil also suitable for water turbines and aero derived gas turbines.
  • PSO Turbine Oil T-series is also suitable for Gas Combine cycle turbine where specified OEM recommendation is applicable.
  • According to suitability of viscosity grade, PSO Turbine Oil T-series can be used in circulating systems for pumps, motors, compressors, mist lubrication systems and hydraulic system, including hydraulic turbine control systems.
     

Benefits

  • Excellent thermal and oxidation stability.
  • Good water tolerance and demulsification characteristics.
  • Protects against corrosion of ferrous and non-ferrous metals.
  • Resists foaming and ability to release entrained air quickly.
