Quality makes no compromise
Development is written large at Tietjen. Tractor and trailer manufacturers as well as legislation require ever more complex systems and Tietjen responds with innovative solutions and concepts that are implemented into the design of air brake systems as amendments and improvements.
Distributors and service workshops consider the continuous development of our pre-assembled components with plug-and-play installation in the individual retrofitting kits to be particularly beneficial. Bills of materials become thus shorter, installation effort is reduced and reliability increased.
Tietjen always delivers products that are state-of-the-art. Made in Germany.
Every installed component is of top quality – assured through the careful selection of suppliers. All parts and every retrofit kit or initial equipment leaving the Tietjen plant is subject to the most rigorous completeness checks. We comply with ISO 9001:2015 as our standard.
