“Valmet offered us state-of the-art technical solutions, and we wanted to purchase their proven key technologies to meet our targets. We are especially eager to see the new type of air dryer being used in practice,” says Lin Qiqun, Chairman of Zhejiang Forest United Paper.
Valmet’s delivery will include four OptiFlo Foudrinier headboxes, an IntelliFormer top forming unit, four OptiCoat Roll coating heads with roll application and a large quantity of OptiDry Coat air dryer units. One of the air dryers is a completely new of its kind, OptiDry Coat double-pass, which combines three dryers in one compact unit, and gives high coating and printing quality, as well as optimized energy-efficiency and runnability. The delivery will also include Valmet DNA machine control system for the coating section and spare parts and consumables packages.
The 6.3m-wide board machine will produce white lined chipboard grades with a basis weight range of 180-350 gsm. The mechanical design speed for the new parts will be 1,000 m/min and daily capacity over 1,800 tonnes.
