Overview

More than 80% of hydraulic system failures are caused by impurities in the oil. The Electrostatic Oil Cleaner (EOC/ELC), available in multiple models, targets exactly the contamination that mechanical and centrifugal filters can miss: sludge, resin, varnish and fine dirt particles that cause friction, wear and eventual malfunction in precision hydraulic components.

The EOC line is built with a superior pump design — the pump mounts directly on a BS14 flange motor, removing the risk of misalignment, and runs on a sturdy shaft with reliable oil seals to prevent leakage. A built-in leakage-sensing mechanism collects any pump or cleaning-cell leak in a safety pan underneath the unit, automatically switching off the pump and flagging the event on screen.

Frequently Asked

Common questions about the Electrostatic Oil Cleaning Machine

What does the Electrostatic Oil Cleaning Machine remove?

It removes sludge, resin, varnish and fine dirt particles from hydraulic oil — contamination that conventional mechanical filters often can't fully catch.

What happens if there's a leak?

The unit's leakage-sensing mechanism collects any leak from the pump or cleaning cell in a safety pan underneath, automatically switches off the pump, and shows the event on the display.

What is the maximum moisture level the EOC can handle?

The maximum allowable moisture level is 500 ppm. Once water enters the unit above that, the electrodes can short due to the collectors, and the collector set needs replacement.
