ANDRITZ recently completed a replacement and start-up of the PM5 Yankee hood at Cascades Tissue Group’s tissue mill in Eau Claire, Wisconsin.

The project was executed by the ANDRITZ tissue team located in Montreal, Quebec, which provides support services for tissue machines and for air and energy systems in the Americas market.

The ANDRITZ PrimeDry Hood is designed for low energy consumption and durability. With this upgrade, production output of PM5 – a medium-speed tissue machine for dry-crepe tissue with a 12-foot Yankee – has increased significantly while reducing specific gas consumption by the hood.


Due to the energy savings achieved, Cascades Tissue Group Wisconsin was awarded the 2020 Energy Efficiency Excellence Award by FOCUS ON ENERGY, Wisconsin’s energy efficiency and renewable energy resources program.

This program encompasses 107 utilities across the state, providing financial incentives to residents and businesses to reduce energy consumption or increase energy efficiency. The Energy Efficiency Excellence Awards honour participants who have shown a commitment to leading in energy efficiency.

“On a tissue machine, the Yankee hood is a key component due to its consumption of energy and its impact on the quality of the final product,” says George Nowakowski, ANDRITZ vice-president tissue drying North America, says in a statement.

“Therefore, it is essential to operate the Yankee hood by the most efficient and economic means possible. The critical parameters are air impingement speed, wet- and dry-hood temperatures, exhaust humidity, and steam pressure in cylinder.”
