In the energy sector, security of supply, efficiency, and availability are key to economic viability and meeting regulatory targets. ONI consistently utilizes waste heat and accelerates retrofits and new construction with prefabricated energy centers—ensuring minimal downtime and significant CO₂ savings.
Heat recovery is a key lever in energy-intensive operations: waste heat from process cooling, compressed air, furnaces, or compressors reduces primary energy demand and energy CAPEX (e.g., lower boiler capacity). In combination with modular energy centers (heat pumps, CHP units, peak load systems, storage), projects can be implemented quickly and at scale. We create the technical prerequisites for ISO 50001-compliant energy optimization.
We begin with an on-site analysis of your load profiles, plant conditions, and process requirements—from which we identify weaknesses, bottlenecks, and opportunities for savings, and, if necessary, prepare a feasibility study to serve as a reliable basis for decision-making.
Further project steps:
In energy facilities (e.g., converter stations, storage facilities, process and infrastructure cooling), cooling circuits and their auxiliary equipment drive up operating costs—which is why the focus is on reducing electricity demand (especially during partial load conditions and high operating hours).
Operators have simultaneous cooling and heating needs—but waste heat from cooling water, compressed air generation, or processes is often discharged unused. The challenge is to technically and efficiently bring this heat to a usable temperature level and permanently integrate it into building heating or process heating.
24/7 operation, redundancy, and rapid service instead of downtime: In the energy sector, temperature issues or cooling/HVAC failures directly lead to performance drops, plant shutdowns, or safety risks. Accordingly, the challenge is to design robust systems (including redundancy), monitor them proactively (remote maintenance), and be able to respond quickly throughout their lifecycle.
