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.
Energy efficiency and environmental protection are the focus of the steel industry: WS delivers major order - retrofitting industrial burners instead of building new plants. The most economical way to comply with emission limits and maximum efficiency.
The targets set for CO2 savings and the reduction of NOx emissions at a well-known automobile manufacturer were achieved by using WS burners with ceramic finned recuperators in gas-fired pusher-type furnaces.
WS has been known worldwide for decades as the undisputed technology and market leader in the field of industrial burner technology for the thermoprocessing industry. For next-generation products, state-of-the-art manufacturing processes such as additive manufacturing are of course also used.
The WS Group was blessed with beautiful weather on April 30, 2025 when almost 500 guests accepted the invitation to "Dance into May" to celebrate the inauguration of two newly built halls in Renningen. With a large number of employees, customers, suppliers and political guests, the day was an entertaining experience that included in-depth technical discussions as well as joint networking.
Federal Cross of Merit for WS founder Joachim A. Wünning: As part of a festive ceremony, Joachim A. Wünning was awarded the Federal Cross of Merit on March 28, 2025. Awarded by Federal President Frank-Walter Steinmeier and presented by Klaus Brenner, the award honors Wünning's life's work.
New CNC lathe at WS - high-end solution for precision and quality in in-house production and new development. The lathe from SPINNER Werkeugmaschinenfabrik GmbH will complement the extensive machine park at WS in the future.
