ETL Verfahrenstechnik GmbH

The history of ETL Verfahrenstechnik GmbH began 30 years ago with the development of powerful filter systems and modules. Since then, the company's activities have concentrated on separation processes, especially the treatment of liquids. In addition to consulting and development/manufacturing of filter systems, membrane modules and smaller test plants for laboratory purposes, ETL is constantly investigating new tasks with regard to possible problem solutions with filtration and membrane technology. The range of services includes standard as well as individual solutions, which perfectly cover the needs of the international clientele.


With the help of our photovoltaic system on the roof, we cover our energy needs largely from renewable energy sources. The excess electricity is stored in a battery and is called up when needed.

In combination with our company building in timber construction and the in-house heat pump, we make a valuable contribution to a sustainable future.
