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.
Thanks to patented gap-flow technology, REKUMAT® S NT burners achieve the highest energy efficiency with the lowest emissions even at low furnace chamber temperatures below 600 °C.
The patented REKUMAT® CR burners allow for the first time the substoichiometric operation of a recuperative burner due to the integrated afterburner. Highest efficiency and lowest NOx emissions thanks to FLOX® technology.
REKUMAT® M series: Energy-efficient recuperative burners for radiant tubes and direct heating. Thanks to FLOX® with extremely low NOx emissions and ready for operation with green hydrogen.
Energy-efficient recuperative burner for indirect and direct heating applications. Revolutionary gap-flow technology for highest possible efficiency.
Energy efficient, ceramic self-recuperative burner for radiant tubes and direct firing
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.
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.
