Valmet will supply a wet end rebuild with installation for Sappi Gratkorn Mill in Austria. The goal of the rebuild is to improve paper machine (PM 9) efficiency, reliability and energy efficiency. The start-up of the rebuilt machine is scheduled for 2019.

The order is included in Valmet's first quarter of 2018 orders received. The value of the order will not be disclosed. The value of an order of this type is typically around EUR 10-20 million.

"Sappi has been relying firmly on Valmet in the past years. In addition to this new rebuild for Sappi Gratkorn, six other major ongoing or already started-up projects for Sappi are Valmet-supplied, the latest ones for Sappi Lanaken (start-up in 2019), Sappi Maastricht (2018), Sappi Sommerset (USA) (2018), Sappi Kirkniemi (start-up 2017) and Sappi Gratkorn PM 11 (2014). Our good OptiPress pressing technology references combined with the outcome of higher solids and better quality were success factors in this case, too," says Senior Paper Technology Manager Riikka Antikainen from Valmet.

Valmet's delivery includes number of modifications to the paper machine wet end. The press section will be rebuilt into an OptiPress Center with modern shoe press technology and the best runnability components available in the market. OptiPress Center provides higher solids and better runnability, thus, lowers energy consumption and improves efficiency. The off-machine coater will be equipped with Valmet Water Jet Turn-up Device for fast parent roll changes. All the equipment will be delivered with installation.
