What Wärmeprozesstechnik does

WS Wärmeprozesstechnik GmbH is a privately held, owner-managed German manufacturer of energy-efficient and low-emission industrial burner systems, founded in 1982 and headquartered in Renningen, Baden-Württemberg. The company serves industrial furnace operators and heat-treatment equipment manufacturers across steel, automotive, and metal-processing verticals, with end customers including thyssenkrupp Steel, Erbacher Härtetechnik, Rexnord Kette, and several furnace OEMs in Germany and abroad.

Its product portfolio is built on the patented FLOX® flameless oxidation combustion technology and the patented Spaltstromtechnologie split-flow architecture, and spans the REKUMAT® recuperator burner family (S, S NT, C, CS, M, CR variants), the REGEMAT® 250 and 350 regenerative burners, the LUVOMAT® line, plus radiant tubes (Strahlrohre) and proprietary burner controls. All current products carry a Green Gas Ready designation for operation with hydrogen and other alternative fuels, supported by an in-house hydrogen electrolyzer commissioned in 2023 and a 400+ kWp photovoltaic installation at the Renningen site.

The business model is consultative direct sales of custom-engineered burner solutions, supplemented by worldwide commissioning, maintenance, repair, and conversion services, plus customer training programs at Renningen or on-site. Pricing is not publicly disclosed and is set per application. Distribution is direct (no catalog channel), supported by wholly-owned US subsidiary WS Thermal Process Technology Inc. in Lorain, Ohio, and via memberships in VDMA, FOGI, IHEA, and the Galvanizers Association. Over 100,000 burners have been delivered cumulatively since 1982, with a high repeat-order rate and customers reporting measured outcomes such as 35% CO2 reduction at specific installations.
