• Maximum chemical and thermal resistance for demanding applications;
• Longer service life and lower maintenance costs;
• Savings of USD 30,000 per year for a South American pulp producer.
The solution was developed for applications in pulp dewatering machines that operate under particularly demanding chemical and thermal conditions. End users report significantly reduced susceptibility to contamination, high wear resistance and longer service life with measurable effects on operating costs.
The performance improvements can be attributed primarily to the robust material properties of CellPress. The low water absorption of the cover reduces the risk of swelling and mechanical deformation. At the same time, the material shows low reactivity to typical process chemicals such as oxygen, ozone, chlorinated components, sodium hydrogen sulfide and methanol. This slows down material-related aging, keeps hardness constant over long periods of time and supports consistent dewatering performance. Due to its high temperature resistance up to 140°C, CellPress is also suitable for positions subject to high thermal load, for example near steam boxes.
CellPress has already been applied successfully in several positions. In a South American pulp production facility, the lump breaker cover was in very good condition after 15 months of operation, allowing it to be reground and reused. This resulted in annual savings of around USD 30,000 for the operator. In a European twin wire press, fabric life was increased from 180 to 260 days despite the highly loaded operating position.
"The outstanding material properties ensure that CellPress can be reliably reused. This enables us to provide our customers in pulp production with a real performance driver that combines efficiency and sustainability."
