Heat Treatment Services During Paper Mill Repair Works in Germany

During the final week of September, our team in Poland received news of immediately required repair works at a paper mill located in the idyllic countryside of Germany. Thanks to our capability for fast mobilization, our heat treatment specialists and heat treatment equipment started their journey towards the paper mill from our Service Center in Poland within a few days.

Scope of Project and Heat Treatment

One of our international partners is responsible for the continuous maintenance of this paper mill, and we are proud to be their trusted heat treatment partner. Our team has a long history of working with them on projects across the globe such as this one.

At this paper mill, there were two cracks on a support ring. Repairs had to be completed quickly to avoid costly downtime.

The cracks had a length of approximately 600mm. The job consisted of grinding and welding preheated material. Our wizards were responsible for the entire preheating process, from installing equipment to supervision and disassembly. As always, all operations were completed according to the highest quality standards and on time.

Equipment for Preheating

Our operators were equipped with Heatmasters semi-automatic preheating units. These thyristor-controlled transformer-type units have been designed with usability in mind: their simple and lightweight structure allows effortless mobility and efficient pre-heating at any location.

Two HM406T heat treatment units and accessories such as thermocouple wire, insulation material, and Heatmasters’ durable ceramic heating elements were required to get this job done.

The HM406T has a power output of 40kW and 6 heating channels. These units are designed for preheating, and they feature our BTC Temperature Control System. It is a simple, bulletproof temperature control system that allows the user to set the holding temperatures and control heating and cooling ramps with just a few buttons.

For any heat treatment processes which require documentation, such as post-weld heat treatment, we suggest our fully automatic units that utilize a digital, computer-based temperature control system. This control system allows complete process control, digital documentation, and features such as on-site/remote monitoring and control.

Half a century of experience in on-site works has allowed us to design equipment and solutions that are innovative and designed with industry requirements such as ease-of-use and a long product lifetime in mind!


Heatmasters looks forward to future challenges utilizing our knowledge and long-term experience in high-quality heat treatment and industrial services.

In addition to on-site pre-heating and post-weld heat treatment (PWHT), Heatmasters provides custom-tailored solutions including:

  • Heat treatment of workpieces in fixed furnaces
  • Heat treatment of large workpieces in portable temporary furnaces
  • Refractory dry-outs
  • Wide range of industrial services (NDT, surface treatment, welding, etc.)
  • High-tech heat treatment equipment (furnaces, transformers, temperature control systems, etc.)
  • Modernizations for all manufacturer’s heat treatment equipment
