Varnish Removal System

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.

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)

Did You Know...

Contamination is the greatest single cause of lubrication malfunction and subsequent excessive wear of parts?

Less than 0.5% of a plant’s maintenance budget is spent purchasing lubricants, but the downstream effects of poor lubrication can impact as much as 30% of a plant’s total maintenance cost each year.
