Our family-owned small-sized enterprise specialises in off-gas cleaning systems. We are involved in new processes and technologies on a regular basis. Over time we have gained experience on all continents with our partners and clients, which has allowed us to continually extend our know-how.

Our personnel, some being employed for more than 30 years, have a high level of competence and broad experience. Our flat organisational structure allows for a quick approach to new challenges and short decision making paths.

Germany, our chosen location for business, provides the ideal environment for us to reach our main objective: Exemplary quality of products and services to achieve utmost customer satisfaction. We apply state-of-the-art techniques, but adhere to traditional and sound values: quality, reliability, consistency and customer focus. THEISEN and Germany are united by these common values.
