Why be concerned about varnish?
Lubricant varnish has become a significant maintenance problem in many critical hydraulic and lubrication oil applications, such as gas turbines, paper machines and compressors. Turbine oil varnish has been a particularly high profile issue over the last decade. A very small amount of varnish that settles in a susceptible zone, such as a fuel control or IGV valve, can prevent the system from starting properly, resulting in a fail-to-start condition or in some cases a unit trip.

Our Varnish Removal Systems (VRS) were developed to address the need to properly remove varnish (also known as lacquer, sludge, or tar) commonly found in various lubrication and hydraulic systems. Our process utilizes either granular adsorbent media or depth media filter elements to effectively remove dissolved and suspended oil degradation products (i.e. the cause of varnish). Varnish removal is accomplished with oxidatively stable media, engineered to selectively remove only the varnish-causing contaminants without disturbing the oil’s additive package.
