VetterTec screw presses are used to dewater fibrous materials of different consistencies, by maintaining mechanical force (electricity). The mechanical is the most efficient way to get rid of the water.

The material is fed to the pressing screw through a feed hopper, and the screw presses conveys it into the compression area, where the product is further compressed during onward transportation. This is achieved reducing the volume in the screw flights of the press. At the end of the compression area, the product leaves the press through the discharge hopper.
VetterTec screw presses are driven by mechanical or hydraulic systems with infinitely variable speed or electronic control.
