WS is a globally leading manufacturer of self-recuperative and self-regenerative burners for the steel and heat-treating industry. WS sold around 100,000 burners since its foundation in 1982 and our burners yield the highest efficiency and lowest NOx emissions on the market. We are proud to be the inventors of the game changing Flameless Oxidation (FLOX®) technology enabling high air preheat temperatures with low NOx emissions. The REKUMAT® self-recuperative burner is available in both direct-fired and indirect-fired (radiant tube) versions. Each version is available in metallic and ceramic (SiSiC) types. The newest burner innovation is the REKUMAT® S burner with the so-called “gap flow recuperator” technology, reaching efficiencies near those of regenerative burners. The REGEMAT® self-regenerative burners integrate regenerators and switching valves into one compact unit, which is why no burner pairs are needed. Both a direct-fired and indirect-fired version is available. An efficiency of up to 88% LHV is possible. Our mission is to provide the highest-efficiency and lowest-emission burners worldwide. We only use the best materials and guarantee for high quality burners engineered and manufactured in Germany with over 30 years of experience. WS has proven that energy efficient combustion systems have become increasingly important. The potential for emission and fuel savings remains huge and the payback times are short even at today’s low energy prices.
