Electrostatic Oil Cleaners

Defeat contaminants in non-conductive fluids once and for all!

Electrostatic Oil Cleaning Systems from Friess remove particles as small as 0.1 µm and aging phenomena such as varnish and oxidation products. This not only increases the service life and durability of the oil, but simultaniously optimizes machine precision and reduces hydraulic malfunctions.

How does Electrostatic Cleaning work?

Our Oil Cleaning System is connected to the oil tank in a bypass flow. The oil is then transported from the reservoir to the Electrostatic Oil Cleaning System by means of a gear pump. There, electrodes charges with a voltage of 14,000 V ensure that contaminants contained in the oil are attracted and deposited on cleaning elements. The innovative Friess principle removes both hard contaminants such as metal particles, seal abrasion or chips, and soft contaminants such as oxidation products, varnish and sticky sludge particles.

The special feature of this method is that you are not limited by the pore size of your filter elements. Unlike other filters, the field forces of an electrostatic field act on particles of all sizes. As a result, you get a particularly clean oil that is even cleaner than new oil! Thus, you save yourself expensive and time-consuming oil changes.

The advantages at a glance:

  • Reduce your oil consumption by up to 90%!
  • Save money on maintenance, repair and oil changes.
  • When in consistent use, hydraulic malfunctions are reduced by up to 70 %.
  • Increase oil life to over 100,000 hours of operation.
  • At the same time, increase the security of your processes.
  • Improve the precision and control accuracy of your machines.
