Long before the broad market recognized the enormous potential that lies in the efficient heating of industrial furnaces, WS developed the efficient recuperative burner REKUMAT® with integrated air preheating. 

Since then, the REKUMAT® has been sold more than 100,000 times and has been continuously further developed. Decades of experience coupled with the WS inventive spirit and numerous patents make the Rekumat® the world's most successful recuperative burner. 

Design variants are available in terms of burner capacity, the materials used, and the combustion technology employed. FLOX® technology ensures the lowest NOx emissions and outstanding service lives. 

The WS principle of offering the burners mainly as complete units with control system and valve sections, which have been extensively tested at the factory, has been proven to simplify commissioning and thus ensure a maximally efficient process for furnace builders and end customers.
