HGH optimized the cleaner plant and approach flow system of German specialty paper manufacturer. As a result of this rebuild, the total volume of the system was reduced significantly. A new 2-stage cleaner plant that can be adapted to the high fluctuating throughputs, achieves an improved cleaning effect of the pulp.

The volume reduction of the overall system results in shorter cleaning and changeover times.

In the course of this optimization, a control system (PCS7) for the approach flow was also implemented.
