Stora Enso Ingerois improves bulk with Aqua cooling calendering
The Stora Enso Ingerois mill wanted to substitute the Yankee process and Yankee cylinder with a process less restrictive on productivity and speed. Aqua cooling calendering is a new bulk-saving calendering technology, which was installed at the mill in the fall of 2015. Prior making the investment decision, Stora Enso run several pilot trials at Valmet's pilot facilities to make sure that they would get the improved quality and raw material efficiency with the rebuild concept.
