Roasting, melting and refining

Individual solutions for unique raw materials

The traditional and long-term available raw material with a constant composition is becoming increasingly rare today. For some time now, our customers have had to deal with complex and constantly changing raw material compositions. And not just in recycling, but increasingly also on the primary raw material side.

With systems designed and delivered by us, our customers can look forward to these market challenges in the long term and safely. Due to our very close partnership product development with the customer every delivered oven is unique. Customers have to adapt their processes to our technology requirements, but our technology adapts very flexibly to customers' process requirements. And not just for the moment. Clever expansion or customization options make the already flexible technologies optimally prepared for future changes.

We specialize in fossil-fired furnace technologies for a wide variety of applications, but now also have much experience in the integration of electrically heated furnace systems in complex process routes, such. As plasma ovens or induction furnaces.
