The value of the order will not be disclosed. The installation is scheduled to start up during spring 2018.

“This will be the first fifth generation Valmet TwinRoll wash press delivery to Finland. The press will give more flexibility in production and ensure an improved washing of the NSSC pulp before the board machine, and in that way, improve the quality of the final product,” says Lari Lammi, Senior Process Manager at Valmet.

“We want to improve the pulp washing efficiency with moderate washing water volumes. A TwinRoll Press showed to be a compact solution when the alternative washers were more in numbers or bigger in size. We are waiting the start-up with great interest to see the TwinRoll Press operation and washing efficiency,” says Timo Riuttanen, Process Development Manager at StoraEnso Heinola mill.

Information about Valmet’s delivery

The scope of delivery includes the Valmet Twinroll evolution wash press (TRPE) with basic engineering, training and site services as well as spare parts. The TRPE wash press features displacement washing and pressing to 30-32% consistency at 2.5-10% feed consistency. The TRPE wash press is ideal for applications where high washing efficiency and capacity are required.
