Our headquarter is in Adenau, which is located right in the heart of the Eifel region. The success of our company is based on customer-oriented solutions at the highest quality level. As a medium-sized plant manufacturer in conveying, process- and environmental technology, we are represented worldwide with our machines in more than 80 countries in the raw materials industry, chemical industry, energy- and environmental technology.
