Special filter designs Verfahrenstechnik Tiemann

The needs of our customers and the requirements from the filter system are of utmost importance to us.

To make sure that the designs are safe, whenever possible, tests are carried out in laboratory or as per benchmarks to find the ideal solution by means of combining and / or adaptation of the known filter systems.

In some applications, however, it was necessary to build prototypes in cooperation with our customers, since no applicable technique was available.
