Wolfgang Oehm – Visionary, pioneer, and driving force behind ONI
The driving force behind the company is its founder and managing partner, Wolfgang Oehm. As a visionary, he recognized as early as the 1970s the enormous significance that energy would have for all of us. As a long-time plant manager at an injection molding machine manufacturer and subsequently at a plastics processing company, he developed the world’s first heat recovery system for plastics machinery in the early 1980s.
Thanks to this invention alone, ONI customers reduce their heating costs by up to 95%!
Oehm is not only a brilliant developer with foresight, but he is also regarded in the plastics industry as a pioneer and trailblazer for the use of energy-saving system technologies. Today, the range of products and services extends from consulting and planning to the turnkey construction of complex, energy-optimized systems in the areas of cooling systems, heat recovery, machine optimization, patented mold temperature control, ventilation systems, cleanroom technology, and compressed air technology, serving a wide variety of industrial sectors.
