Process and control today | Valmet to supply microwave consistency measurements to SCA’s Ortviken plant in Sweden

The order is included in the Valmet orders received in the fourth quarter of 2021. The measurements will be delivered during the first quarter of 2022.

“We evaluated different applications and found Valmet’s solution to be the best. In this project the crusher is extended from existing process sections where we have already been using Valmet MCAs for ten years. When the responsible production staff asked us to continue using these metrics, it was an easy choice, “says Patrik pettersson, Project engineer, SCA.

“We have been cooperating with SCA Ortviken for a long time to develop a world-class CTMP factory and this order further deepens our relationship. The reconstruction project has been underway for a year now and these microwave consistency measurements complement Valmet’s broad scope of delivery in the project, “says Andreas Lindstedt, Corporate Account Manager, Services, Valmet.

It offers a wide range of consistency (0-16 Cs%) for different applications in the pulp and paper industry. The sensor is easy to install and does not require regular maintenance, reducing commissioning and running costs to a minimum.
