Heat recovery - saving energy through innovative technology

Exhibitor
ONI-Wärmetrafo GmbH

Our heat recovery systems use waste heat from industrial processes (e.g., compressed air, cooling water, hydraulics) to heat halls, offices, or break rooms – starting at just 35 °C.

This means that energy that has been paid for once can be used multiple times, significantly reducing energy costs and protecting the environment. In many cases, boilers and large heating systems can be completely replaced – the systems require little space and pay for themselves quickly, often even without equity capital through leasing.
