The service-friendly Varnish Elimination Unit (VEU) is designed for use with mineral oils and is particularly effective at removing oil-aging products (varnish). Varnish takes the form of oil-insoluble aging products which settle in the tank, in valves, or in bearings. These can be filterable gels or solid paint-type deposits. The VEU series product is used in bypass flow. The removal of varnish is based on reducing the oil solubility for varnish with subsequent filtration, using a combination of an air cooled heat exchanger in series with DiMicron series filter elements.
