50 years of D+H

From development garage to global player

The beginning was almost idyllic. It was located on Brockdorfstraße in Hamburg's Rahlstedt district, where the start-up company "Dingfelder + Hadler" (which later became D+H) originated in a garage in 1968. It has been a long time since the two-man operation working out of a tiny garage developed into a medium-sized group of companies with more than 500 employees worldwide and an annual turnover of about 60 million euros. The 50-year success story of D+H is also the history of two families who today  ̶  led in the second generation by Dirk Dingfelder (CEO) and Christoph Kern (CSO)  ̶  set the course of the group of companies towards the future.  

“Who would not love developing solutions that satisfy the basic needs of all people? Whenever air and life are concerned, we are in our element,” says Dirk Dingfelder, CEO of D+H Mechatronic AG. As manufacturers of systems for smoke extraction and natural ventilation, the fresh air providers and lifesaving rescuers at D+H will celebrate their fiftieth anniversary in the summer of 2018. Dingfelder continues, “D+H doesn’t just produce intelligent systems that open and close windows in buildings. D+H is concerned with far more than technologies for smoke extraction and natural ventilation.” Christoph Kern, CSO of D+H Mechatronic AG adds, “We make buildings breathe! And that means we bring protection and security as well as comfort and well-being to people. So much so that we have based our claim on this: BUILDING ATMOSPHERE.”

From development garage to innovation driver

For the last half century, D+H has significantly contributed to the SHEV and ventilation industry and has left its mark on it with many innovations. One of them was the KA series of chain drives. The KA 30 was the first chain drive that D+H developed and manufactured itself.
