Valmet will rebuild a sack kraft paper machine at Mondi's Štêtí mill in Czech Republic. Valmet's delivery for the paper machine 5 (PM5) will include the modernization of the press section. The targets of the rebuild are increased production efficiency and improved machine runnability, while ensuring safe working environment. The rebuilt production line will start-up during the fourth quarter of 2015.


The order was included in Valmet's third quarter 2014 orders received. The value of the order is not disclosed.


"Our target was to have a reliable high performing press concept for our PM 5. Valmet was able to offer their OptiPress concept which provides a balance of a well proven technology with innovative technical solutions. The further development of this press type provides also for the operators the possibility to operate and maintain the press in a safe and efficient way," says Lars Mallasch, Technical Director Packaging Paper, Head of Capital Expenditure Mondi E&I.


"We have strong track record on modularly designed and built paper and board lines and the same modular approach can be utilized in rebuilds too. For customers, this means resource saving solutions that are fast to install and safe to use and maintain," says Reijo Koivuranta, Press Sections Product Manager at Valmet.


Key features of the delivery

The existing press section at PM5 will be rebuilt into OptiPress Center press section. With this tri-nip solution, the new 1st press, the 2nd press and the 3rd press shoe nip maximizes the dry content entering the dryer section and increases the wet strength of the paper.  The resulting boost in dryness thus fully benefits web runnability in the open draw and in the beginning of the dryer section. Felt conditioning is done effectively with uhle boxes equipped with perforated covers. This results in improved dewatering and lower energy consumption.


The simplified frame construction of modular press section design means low load to foundation, space savings, shorter shutdown and faster installation. Fabric changes are possible with the help of a fabric insertion unit, as there is no cantilevering. User friendly design like new walkways emphasize safety and easy maintenance.


The rebuild also includes a new press pulper and modifications at the dryer section.
