In 2007, an indirectly heated roller hearth furnace (built by Wienstroth Wärmebehandlungstechnik GmbH) with energy-efficient REKUMAT® burners was put into operation at a Schaeffler plant in Germany.
These burners were already serviced last fall at WS Wärmeprozesstechnik GmbH in Renningen and adapted so that, thanks to the FLOX® technology with both natural gas and H2 can be operated as a fuel with high efficiency and lowest emissions. Successful commissioning with natural gas has already been carried out by Wienstroth. After the hydrogen infrastructure has been established, commissioning will be carried out with H2 as fuel gas.
With this and other conversions as well as newly built projects, Schaeffler is demonstrating its comprehensive commitment to sustainability while investing in the long-term future of the respective plants.
Due to the decades of experience at WS Wärmeprozesstechnik GmbH with hydrogen as well as the patented FLOX® technology, the adaptation to H2 as fuel is possible for many existing plants with reasonable effort, without having to install new burners. In addition, significant efficiency gains can be realized for many plants. Until the necessary hydrogen infrastructure is available, continued operation on natural gas or mixtures of natural gas and hydrogen is possible.
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.
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.
