Who we are

ENTECCOgroup is an owner-managed, independent group of companies that invests in medium-sized companies in the field of environmental technology. The companies of the ENTECCOgroup manufacture highly effective and at the same time highly efficient filter products and use them to create turnkey plants for dust removal, exhaust gas purification or aeration and ventilation for almost all industries.

As a specialised team of experts, the ENTECCOgroup benefits from numerous synergies, and draws on a wealth of experience. In addition, it has access to a large number of connections and cooperations, e.g. with environmental ministries, universities and research institutes. ENTECCOgroup reacts quickly, acts responsibly and arrives at leading solutions through networked expertise.


As a company in the field of environmental technology, we have learned from nature and have taken a closer look at the behavior patterns of a swarm or flock. A swarm consists of many individuals. And yet it acts like a homogenous organism and displays amazing skills as a whole. This creates complex adaptive systems in nature, known as the emergence phenomenon.

The formerly partially independent companies were incorporated into the ENTECCOgroup swarm under the buy and build strategy. Each company sells all the Group’s products and solutions, with the sites focusing primarily on their home markets.
