Description: Valmet will supply an automation system update and expansion for Gasum’s project at the Metsä Tissue Mänttä mill in Finland.

Valmet’s automation system will be used to control the burners of the drying processes and manage a gas terminal that will be connected to Valmet’s data collection application. The delivery will standardize and optimize the tissue drying process and quality management.
