Corrosion is a common problem with vacuum rolls that can have a significant impact on production output and costs. PR Rolls, an experienced specialist in this field, offers an efficient solution: professional grinding of the affected cylinders and subsequent protection with the TecnoClean coating.

Success Story: Cooperation with Koehler Kehl GmbH
Koehler Kehl GmbH, a leading family business in Germany, was struggling with massive corrosion on the DuoStabi rolls in the pre-dryer section of the PM 2 paper machine. Despite several attempts to solve the problem with another supplier, they were unsuccessful. Finally, the company turned to PR Rolls to find a permanent solution.

Joachim Fuchs, Production Manager of Line 2 at Koehler Kehl GmbH, describes the successful collaboration:

‘We had a massive problem with corrosion on the Vacuum Rolls in the pre-dryer section of the PM 2. PR Rolls solved this problem with professional grinding and the TecnoClean coating. This enabled us to reset the running times of the dryer fabrics from around four months to the standard running time of 540 days!’

The TecnoClean coating developed by PR Rolls offers numerous advantages:

• Longevity: 5-year guarantee on the coating.
• Quality: The professional grinding method and the use of optimised materials and parameters guarantee high efficiency.
• Cost Reduction: The standard running times of the drying screens were achieved, which minimised downtimes and reduced operating costs.

Joachim Fuchs emphasises the positive effects:

‘Thanks to the standard running times achieved, we were able to significantly reduce downtimes and bring the costs for the dryer fabrics down to a normal level.’

In addition to the technical solution, Koehler Kehl GmbH also praises the comprehensive service provided by PR Rolls:

‘The service was carried out in an extremely coordinated and systematic manner. PR Rolls fully met our high requirements in terms of occupational safety, cleanliness and tidiness.’

Jani Westerlund, Managing Director of PR Rolls, is satisfied with the success of the project:

‘We know that the customer places high demands on its service providers. The TecnoClean coating has made a significant contribution to solving the corrosion problem. The secret of its longevity lies in the combination of precise grinding technology, the materials chosen and the expertise of our team.’

With this successful partnership, PR Rolls once again proves that innovative technologies and professional working methods lead to measurable success.
