Valmet will supply a sizing section rebuild to Productora Nacional de Papel in Mexico. In the project, the board machine 1 (BM 1) will be upgraded to improve strength properties and add new coated white-top testliner grades (WTL) to the machine’s product portfolio. The start-up of the rebuilt machine is scheduled to take place by the end of 2023. The order is included in Valmet’s orders received for Q1 2022. The total value of an order of this type and delivery scope is typically around EUR 15–20M.
Valmet’s delivery for BM 1 will include a new OptiRun Hybrid afterdryer section to increase the machine’s drying capacity. OptiSizer Film with supply systems will be installed to improve board strength. The sizer will be followed by a TurnFloat web turning unit, an OptiDry Coat air dryer and an OptiAir heat recovery system for the air dryers. The delivery will also include spare parts and consumables.
