The oil containing water is pumped through a dewatering element. The dewatering element is equipped with fibres that are able to absorb water. The small water droplets that are distributed in the oil are absorbed by the filter material. The oil will flow through the pores of the filter element while the water remains in the filter material. Due to the water absorption the fibres expand and the filter pores are reduced. The differential pressure in the filter element increases. As soon as the filter element is saturated with water, the dewatering element has to be exchanged. By removing the water in the oil continuously the service life of the oil can be significantly increased.


  • Significant reduction in oil consumption
  • Significantly lower costs for maintenance and repair
  • Less hydraulic troubles
  • Increased process safety due to improved lubrication effect


  • Removal of condensation water from portable hydraulic systems
  • Removal of condensation water from lubrication systems in the paper industry
  • Dewatering of transformer oils
