Service 4 you

Benefit from our expert and worldwide accessible services. This ensures shorter distances for faster customer support. If you are satisfied, then so we are.

Engineering and consulting

Under-dimensioning leads to performance deficits: but over-dimensioning results in unnecessary expense. Our service prevents both. Long years of experience and extensive process expertise pay off in the exact design of your system. Since the functioning of a filter system is influenced by many product and operational parameters, all these factors that impact on the system must be evaluated in advance. We have a wide selection of possibilities for customized design here. The result: a filter system all of whose parameters are exactly matched to your individual requirements. For the extraction and the treatment of process gases, or the design of the required equipment assemblies – we will gladly provide you with the necessary consulting and support.
