ACO Passavant Detego

System provider with tradition

As part of the ACO Group, ACO Passavant Detego is the specialist for all types of technical manhole covers, for both standardised and customised solutions, in the industrial and infrastructure sectors. We are the European innovation and market leader in this field. There is no way past ACO Passavant Detego, especially for emergency exits and manhole covers in heavy-duty areas.

We not only offer a wide range of standard products, but also enable every conceivable custom solution for manhole covers. Safe performance is our top priority for each of our products. Another unique selling point is our aesthetic standard: we find solutions that blend harmoniously into the local architecture and, at best, go completely unnoticed.

Our production sites are located in Aarbergen and Mülheim-Kärlich. In the Michelbacher Hütte in Aarbergen, cast iron products for road and building drainage have been produced under the brand name Passavant since the 19th century. Building on this tradition as part of the ACO Group, we continue to expand our unique expertise and technical edge with every project and every innovation.
