Filtration & Monitoring Solutions for hydraulic oil and lubricants

Off-Line Unit for varnish removal

The plant in Putte was established in 1929 and today has 46 injection moulding machines ranging in clamping force from 35 to 2,700 tonnes.

One ENGEL injection moulding machine is contaminated with Varnish. Previous filter actions resulted in clean oil but no elimination of the Varnish. Especially when the oil is <40°C varnish tends to clog valves, filters and other small passages.

The solution for Polytec was a RMF Off-Line Filterunit.
