Customer case:

Coating kitchen automation renewal at Norske Skog Bruck

Dec 5, 2017

Faced with end-of-life issues for its coating kitchen automation system, Norske Skog in Bruck an der Mur, Austria turned to Valmet for a replacement solution. The coating kitchen is a key process in the production of light weight coated paper from the mill’s PM4 paper machine and reliability is of vital to the continuous running of the machine.

We have other Valmet systems in the mill and with the experience gained from them, Valmet DNA was an obvious choice.”
Horst Gottsbacher, automation engineering specialist
Since the Valmet DNA startup we have never run out of coating color. All members of the project, both mill and Valmet personnel, worked really well together and I have to say that this has been the best project I have participated in.”
