The existing control systems of two supercalenders in the paper mill had to be replaced by a new control system with new user interfaces. Some of the electrical and control components were replaced at the same time. The project had to be carried out during a production shutdown of only four days.


The renewed control systems significantly improved the reliability and efficiency of the supercalenders. In addition, the life cycle of supercalenders was significantly extended, as the new systems also ensure the availability of spare parts for components in case of failure.
