Hydraulic Screen Changers

From the worldwide leader in filtration equipment, Xaloy offers the EH hydraulic screen changers.

Contamination of the melt steam by metal, wood, paper or internally generated black specks yields products that are unacceptable in appearance and/or performance. Xaloy hydraulic screen changers represent the most technically advanced design of slide plate type screen changers. The EH line is suitable for processing a wide variety of thermoplastics on applications ranging from sophisticated multiple layer thin  film extrusion to the heavy demands of recycling.

Integrate the System

Put an Xaloy melt pump after the screen changer and further increase the productivity of the extrusion line – all from one company.
