Our factory

The main BENNINGHOVEN factory in Wittlich

Where quality is made — The world's largest and most modern factory for manufacturing asphalt mixing plants offers optimum conditions for production at the highest level.

The production is structured according to the flow of materials and precisely adapted to the plants thanks to the generous capacities. One crucial advantage is the positioning of the complete production chain under one roof – from pre-fabrication to dispatch. Order-neutral pre-fabrication and the clever plant concept with modular components create a high level of flexibility in planning, achieving short delivery times and prompt start of assembly.

The factory is equipped with a range of advanced technologies and sets new standards for production technology. The innovative layered ventilation system, the intelligent lighting and energy concepts and the modern coating systems with solvent-free powder coating are some of the stand-out features. Another important focus was on work comfort, health and safety, emissions protection and a good work climate.
