Until today, wire annealing furnaces were almost exclusively heated directly with cold air burners. In most cases, several cold air burners are installed in the individual zones and the furnace temperature is controlled by proportional operation of these burners.

The Künne Stahldrahtwerk in Hemer has now ordered a new furnace with an innovative design. Highly efficient WS REKUMAT® burners of different design and inputs will comprise the heating system. Thanks to the FLOX® technology, all burners are capable of being operated with natural gas as well as hydrogen with very high efficiency and lowest emissions.

With this new project, the Künne Group is continuing its comprehensive commitment to environmental protection while investing in the long-term future of its plant portfolio. Due to the decades of experience at WS Wärmeprozesstechnik GmbH with feed gases containing hydrogen as well as the patented FLOX® technology, it is possible to design modern heating systems that are already today prepared for the future with alternative fuels.


Research field of thermal process technology

The new research field of thermal process technology is dedicated to the goal of defossilizing high-temperature processes above 1,000 °C. While some processes are flexible enough to be heated with renewable electricity, climate-neutral fuels will be necessary for many applications in the future.


REGEMAT® 250: Strong increase in sales figures

Continuous and recently even particularly strong increases in sales figures prove that the REGEMAT® 250 is the new gold standard for modern strip galvanizing lines. Customers are impressed by the lowest NOx values with maximum efficiency as well as its future viability thanks to its outstanding suitability for operation with hydrogen.


Start of 2024: Innovation & investment

The WS Group is looking forward to an exciting and successful year 2024. We are expecting the completion and commissioning of several pioneering investments. On the product side, our customers can also look forward to various innovations and further developments that will make a decisive contribution to their success in achieving true sustainability. 


Thermprocess 2023

Highly efficient, flexible and with the lowest emissions in the industry. These are the burner products that WS will present to the trade public at Thermprocess 2023.

Once again, WS sets the tone when it comes to modern gas heating: fuel-flexible, efficient and low-emission across the entire product range.
