In more than 70 countries in the world customers rely on high-quality and energy-saving ONI system solutions.
Our program of products ranges from small chillers to large industrial plants today in the fields of machine cooling, process cooling, heat recovery, air conditioning, ventilation and clear-room technology, compressed air, machine optimization and temperature control.

Reduce cycle times, cut unit costs!
RHYTEMPER® temperature control systems minimize the cycle times and monitor the production process permanently. In practical work reductions in cycle times of 18 % are achieved on an average. In some cases up to 40 % are achieved.

Even for smaller plant systems with cooling requirements from 5 to 160 kW needing water temperatures from 20°C and less at constant values over the whole year, our chiller series LKK, WKK and LKK-TE with PRO-Effizienz control system offers a complete range of systems.

The FlowWatch ® is a compact water distributor with integrated electronic flow and temperature monitoring of several individual circuits. The system is insensitive to pressure surges and convinces with high measurement accuracy.
