New aqua cooling calendering technology: first delivery to Stora Enso


Valmet has launched a new and patented calendering technology to the market. The new aqua cooling technology improves the calendering results compared to usual paper production conditions. Aqua cooling calendering is aimed for making the end-product more lightweight, without compromising functional and visual properties. This will lead to substantial reduction of energy and raw material usage. Aqua cooling calendering technology will complement Valmet’s bulk-saving calendering offering, which includes the revolutionary metal belt calendering as the ultimate lightweighting solution. Valmet has a pilot machine with aqua cooling technology available for customer trials.

Stora Enso has decided to invest in this new aqua cooling calendering technology at their BM 4 packaging board machine in Ingerois, Finland. The target of the rebuild is to improve board quality, while also increasing bulk saving potential. The rebuild includes new web moisturizing and evaporation cooling equipment and is scheduled to start up in September 2015.

The order is included in Valmet’s first quarter 2015 orders received. The value of the order will not be disclosed.
