HYDAC Varnish Elimination
HYDAC VEU-F Varnish Elimination Unit
The service-friendly HYDAC VEU-F Varnish Elimination Unit series is used to prepare mineral oils. They are particularly effective at removing oil ageing products (varnish) from mineral oils. Varnish takes the form of oil-insoluble oil ageing products which settle in the tank, in valves or in bearings. These can be filterable gels or solid paint-type deposits. The VEU-F series of units is used in bypass flow. The removal of varnish is based on reducing the oil solubility for varnish with subsequent filtration.
Benefits of the HYDAC VEU-F Varnish Elimination Unit
- Removal of solid or gel-like oil aging products.
- Increased operating reliability of the system as a result of fewer deposits in hydraulic valves.
- Increase in the oil service life.
- Available as a complete unit for retrofitting to existing systems and for new systems.
