Synthetic Turbine Hydraulic Oil

  • Base Oil Technology: Synthetic
  • Viscosity Range: ISO 32
  • Viscosity Index: 282

AMSOIL Industrial Synthetic Turbine Hydraulic Oil is engineered for superior performance and long oil life in industrial applications subjected to frequent low-temperature operation. Its high-quality synthetic base oils ensure exceptional fluidity in sub-zero temperatures for increased startup performance, while its ultra-high viscosity index translates into good film thickness and wear protection at operating temperatures. It provides dependable operation throughout a wider temperature range than conventional hydraulic oils.

  • Superior low-temperature fluidity reduces pump cavitation, provides immediate flow and reduces the need for seasonal change-outs.
  • Potent oxidation inhibitors maximize fluid life while fighting sludge and varnish for clean, efficient operation.
  • Excellent demulsibility helps improve operation in humid and wet environments while improving filterability.
  • Resists foam to help prevent pump cavitation and improve heat dissipation for better wear protection.
  • Excellent valve operation in cold temperatures.
  • Excellent seal compatibility for long seal integrity.
  • Exceptional filtration even in the presence of water.

 

MAXIMUM WEAR PROTECTION

  • Formulated with molecularly uniform synthetic base oils to reduce friction in valves, pumps and hydraulic-system components for efficient operation and reduced wear.
  • High-performance anti-wear additives use zinc to help prolong component life and reduce maintenance costs.

 

RESISTS OXIDATION

  • Formulated with oxidation inhibitors that resist acid and sludge formation.
  • Robust formula reduces the need for frequent oil changes due to degraded oil or seasonal temperatures, making it ideal for extreme temperature ranges and applications that may be difficult to access.

 

ALL-SEASON PROTECTION

  • Features a high viscosity index, meaning it retains its protective viscosity in elevated heat to provide reliable wear protection.
  • Remains fluid in sub-zero temperatures for maximum performance in all temperature extremes.
