Varnish Removal System

Varnish is a common problem for a wide range of hydraulic fluids and lubricants, especially in turbine and plastic injection molding applications. It results in stickiness around the valves, shorter fluid life, shorter filter life and unscheduled downtime.

This is the most complete varnish removal and prevention system on the market. It removes oxidation by-products and prevents varnish formation during the cool down.

Features

Benefits

  • Reduces the rate of additive consumption
  •  Reduces and prevents servo valve sticking
  • Removes oxidation by-products
  • Does not add water or other by-products to the system
  • Operates at a wide range of oil temperatures
  • Compatible with all mineral and phosphate ester fluids
  • Operates on fluids containing more than 500 ppm of water

Industries and Applications

Varnish is a common problem often seen in applications that use the new group II & III base oils. It’s a result of water problems, air problems, temperature fluctuations and oil degradation. This is often a problem in a variety of industrial applications like…

  • Power generation (turbines)
  • Steel, copper, aluminum (presses)
  • Pulp and paper (paper machines)
  • Plastic injection molding and blow molding
  • Automotive and tires (stamping / forging / curing)
  • Petrochemical (compressors)
  • Aerospace (flight simulators)
