Our philosophy – your advantage
Because quality means more than just selling excellent products: TTC advises its partners in advance – on the latest air conditioning technology, on high-quality lighting for indoors and outdoors. Even when it comes to elegant grilles that should fit harmoniously into the overall design of a building. We offer sophisticated, proven solutions as well as individual, tailor-made custom-made products.
TTC is a German, family-run company in its third generation: Just like his father Siegfried Timmler, his successor Patrick Timmler is driving forward the internationalization of contacts and sales markets as Managing Director. This means customers in Asia, Australia and the USA. In Germany, medium-sized customers and large corporations alike appreciate the quality “Made in Germany”.
Our performance is based on the continuous development of innovative products. This is done in-house by our own design specialists. Years of expertise, close contact with architects, lighting designers, engineering firms and landscape planners, reliable cooperation with suppliers in Germany and Europe, dedicated service, personal exchange: all this is TTC.
P.S. We attach great importance to manufacturing in a way that conserves resources. Many of our products can be completely dismantled at the end of their life cycle and their individual components can be recycled.
