The IEA Team has developed the screw press for sludge dewatering in 1990 and since 2005 it is marketed in Europe and since 2010 produced in Austria by IEA Derflinger GmbH. Over 200 references of sludge dewatering plants with the IEA screw press as dewatering unit where supplied in the last 10 years in Europe where IEA was solely responsible for assembly and commissioning  which shows the experience in this market segment.

The coordination of service is carried out by the company headquarter in A-4055 Pucking near Linz or directly by the respective national partners. Due to our diversity of types - more than 40 types of screw press (from 10 to 2000 kg dry solids per hour) - we offer the best possible solution for every application.
