Preparing and maintaining quality standards - so that you attain the expected quality

DIN EN ISO 9001:2015

Quality management system

The company-related quality management system of Tiefenbach Control Systems GmbH is the basis for maintaining and continually improving the quality standards of our products.

For many years it has been our aim to meet the requirements of DIN EN ISO 9001 in order to deliver a consistently high quality to our customers and business partners.

Our process-oriented day-to-day approach to business provides for markedly verifiable and optimized work flows in all areas of the company. These activities also involve the task of carefully selecting suppliers with a very high quality standard and an excellent quality awareness.

Furthermore, our quality management standard ensures a constant refinement in terms of a continual improvement process.

Customer satisfaction is a major priority for our personnel in everything they do.

ATEX - our area of expertise

The major part of our products is used in potentially explosive atmospheres.

Only equipment and protective systems which are certified and marked accordingly are allowed to be put into operation in these areas. Basis for the certification is the European Directive 2014/34/EU.

The Directive 2014/34/EU lays down the essential health and safety requirements relating to the design and construction of equipment and protective systems intended for use in potentially explosive atmospheres.

By untertaking the conformity assessment procedure that applies to a specific product Tiefenbach Control Systems GmbH ensures and declares that the respective equipment meets the applicable requirements of the Directive 2014/34/EU.

IECEx - standards

In addition to the demanding ATEX requirements we also fulfill the internationally applicable IECEx standards for products used in potentially explosive atmospheres.

We are thus in a position to offer our products on the global market.
