Customer case:
Sellable sack kraft paper in just three days after press section rebuild
Aug 18, 2016
Modular design made the rebuild of the entire press section of PM 5 at Mondi's Štêtí mill very easy. Only one week was needed for commissioning and start-up. Minimized shutdown was achieved as the press section was pre-assembled for fast onsite assembly and it's smart modular design reduced the civil works needed. Also, both technology and automation was supplied by Valmet which ensured smooth project all the way.
All the efficiency figures like time efficiency, material efficiency and speed efficiency have improved compared to the values we had before the rebuild.
