Maximal system performance

The key point is the movable screen basket of the screw press AKUPRESS. Hence with this system the AKUPRESS allows a sensitive adjustment of the dewatering pressure for optimal dewatering results. In addition, with the integrated sedimentation the AKUPRESS reaches best filtrate and high capture rates. Through a discontinuous and minimal spray water requirement with own filtrate the AKUPRESS doesn’t need extra filtrate quantity. Generally, the machine has a long service lifetime and easy maintenance due to armoured screw spiral, flanged screw or split screen baskets. In addition, our screw presses have low energy consumption and operation cost. In short, the AKUPRESS shows maximal system performance.
