SUCCESS STORY from 1986 to this day

Gerald Hehenberger, founder and CEO of SET GmbH, has consistently played a leading role in system development over the past 30 years. Right from the very beginning of the wind industry he has been among the pioneers in developing new technologies for drive Systems.

The evolutionary path started in the mid-eighties with the development of one of the first 600 kW variable-speed, pitch-controlled turbines, followed by doubly-fed induction-generator systems in the mid-nineties, and multi-megawatt offshore WECs in the early years of this century. With SETCON® for industry and DSgen-set® for wind energy, he has taken SET GmbH to a level that sets new standards in drive technology.
