This section provides the customer with product related information resources such as applications and literature but also with tools like questionnaires. This makes it easier for the customer to find his way around and select the right product with the right configuration.

Customize your system

After the Product Finder for Water & TOC we have designed our detailed questionnaire to find the right configuration of a system. So the customer can tell us his requirements by answering the questions. Try it out right now!

Application notes

In the following you will find applications that have been developed on our own initiative or in the context of customer inquiries and/or cooperation with various institutes and facilities. If you also have an inquiry, please send us a message to We are always interested in the development of new applications.
