With the development of the FLOX® burner REKUMAT® S, WS has once again succeeded in revolutionizing the recuperative burner. A tripling of the heat exchanger surface due to the patented gap flow technology enables groundbreaking efficiency. Thanks to "FLOX® inside", the burners achieve the lowest NOx emissions even at extremely high efficiency.
Due to the scalability of the recuperator, the burner is always perfectly adapted to the respective application. With efficiencies >80%, the REKUMAT® S achieves the efficiency of a regenerative burner even at lower outputs.

Sustainability and efficiency were the key objectives in the design of thyssenkrupp's state-of-the-art hot-dip coating line FBA 10. COO Dr. Heike Denecke-Arnold and Dr. Clemens Trachternach, Team Leader FBA 10, provide an exciting insight into the various parts of the ultra-modern line.
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.
