Locations: Global Presence

At its ONI locations, the company centralizes development, manufacturing, and project management—with streamlined processes and clear points of contact. In addition to its headquarters in Lindlar, its international presence (including a manufacturing facility in Kunshan, China) ensures the efficient implementation of global projects. The network is complemented by ONI Temperiertechnik Rhytemper GmbH in Großröhrsdorf, a specialist in innovative temperature control solutions.

Headquarters in Lindlar

ONI-Wärmetrafo GmbH

Our main plant, located in Lindlar in the Oberbergischer Kreis district between Gummersbach and Cologne, houses all specialized departments at a single location. This allows every step of the process—from planning to the turnkey final assembly of the finished system—to be coordinated as effectively as possible.
Project management is also based at this location and, in coordination with purchasing, warehousing, assembly, and shipping, can efficiently execute even international projects thanks to short communication channels.
