WEPA boosts capacity with rebuilds; Leuna mill investment latest

German tissue manufacturer WEPA has invested in a total of seven Toscotec-supplied custom-made hood and air system rebuilds on a turnkey basis.

Toscotec has supplied the complete package for the rebuild, from its engineering design, to the components supply, down to onsite dismantling operations, erection, commissioning and start-up.

For these rebuilds, the machinery supplier developed a custom-made design of its hoods aimed to increase production and reduce energy consumption to a minimum; it engineered the nozzle boxes and customised the air system according to WEPA’s requirements, in order to achieve top operation flexibility in cross direction moisture control and better machine runnability.

Toscotec supplied other hood and air systems to WEPA in Germany, France and Poland as part of the supply of new tissue lines.

The following three projects are a selection of the rebuilds carried out from 2006 to 2019.

Most recently included the rebuild of PM10’s hood at Germany-based WEPA Leuna’s in 2019.

Lars-Helge Peters, WEPA Leuna mill manager, said: “Inside the building we had to do a big crane job with evident space restraints, but Toscotec handled it very well.


“During the six months after the rebuild, we achieved two positive results: the first is a 3-5% reduction of PM10 overall energy consumption (gas and electrical power) and the second is the improvement of the moisture profile across all grades, from kitchen towel to toilet paper.

“Also, on this new configuration, compared with the old hoods, we observed an increased stability of the hood section and better runnability.”

The supplier said that the results of seven hood rebuilding projects over 13 years have been the “consistent reduction of gas and power consumption higher than the contract guarantees, and a significant increase in the runnability of the machine, both in terms of overall efficiency and cross direction moisture profile.”
