MDT Garantie

Made in Germany

Development and production

MDT develops and produces its own KNX products in Engelskirchen (near Cologne) in Germany. Thousands of products leave the plant every day, and the products are usually available from stock. This is made possible thanks to the flexibly organised production, which is flexibly geared towards demand. More than 100 employees at the site manufacture the KNX components in various production levels.

We’re here for you


Our support colleagues are all experts and between them have decades of practical KNX experience. They are based at our company headquarters in Engelskirchen and answer the phone directly – when you call us you do not have to click through a digital switchboard system. The best thing is that our KNXperts will help you until the problem is resolved. We aim to provide the best support on the market, and we welcome your feedback.
