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
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.
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.
