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.
Just in time for the start of the year, the WS Service department is delighted to have taken over and used the new WS Service Center. After extensive conversion work in the newly acquired building, nothing now stands in the way of its use as the new control center for our service department.
There was a lot to celebrate at the WS Summer Party 2024. Around 250 guests spent a thoroughly successful day in Renningen in the best weather and found out about the many new developments in the WS Group. Good food and a cold drink or two ensured a great atmosphere and fond memories.
Several high-ranking delegations from China visited WS in Renningen to find out about the best industrial burner technology available. The focus of the visit was on the low-emission and efficient heating of electric conveyor belt systems. Due to the increasing production of electric vehicles, this market segment is currently experiencing an upswing, particularly in Asia.
Fast for the few or slow for everyone? WS is pursuing its own concept when it comes to expanding the charging infrastructure for electric vehicles. In order to achieve a low-cost yet effective charging system on the factory premises, WS consistently relies on a low charging capacity.
With the help of a new electrolyser and surplus electricity from its own PV systems with a capacity of over 400 kWp, WS will supply the laboratories in Renningen with green hydrogen in future. Following the installation of the electrolyser at the end of 2023, the storage and pipeline infrastructure is now also fully operational.
Rexnord Kette GmbH and WS have successfully modernized a belt furnace, reducing the furnace's CO2 emissions by 35%. In addition to new burners with maximum energy efficiency, the optimization of the operating mode also contributes to the CO2 reduction.
