Turn free waste heat into valuable usable energy through heat recovery!
Our heat recovery systems are used worldwide by customers across a wide range of industries. This not only helps customers reduce their energy costs but also makes a significant contribution to reducing their environmental impact.

Optimizing Energy Consumption Through Innovative Technology
Waste heat is available for further use in nearly every industrial facility!
For example, from compressed air generation, cooling water, or a wide variety of thermal processes. Even waste heat from cooling water with a temperature of 35 °C can be ideally utilized for heating offices, break rooms, and factory buildings through the use of our heat recovery systems.
With this system technology, energy that has been paid for is used not just once, but at least twice or even three times. Especially in energy-intensive facilities where processes and machinery are cooled, and where hardening and annealing furnaces or melting plants are operated, there are ideal opportunities for implementing heat recovery—provided there is a need for heating energy or process heat and this energy has previously had to be generated using expensive primary energy sources.
Heating with free waste heat
The investment costs for a heating plant with boilers, burners, and a chimney system are substantial! Not only do the costs for the system components add up, but so does the necessary building infrastructure. Furthermore, a business owner would much rather use the space required for a heating plant with boilers for production machinery and equipment.
We have implemented energy supply concepts for customers that do not require a boiler system!
For example, for plastics processors who cover 90% or more of their heating needs using waste heat from machines or processes. Only during periods when no waste heat is available is the shortfall in heating provided by electric heating elements. This option requires extremely little space, even at high output levels.
Energy costs are becoming a problem that should not be underestimated, particularly in energy-intensive businesses. Consequently, this cost factor is having an increasingly significant impact on companies’ competitiveness.
In response to this trend, more and more businesses are now adopting proactive energy-saving policies. One example is the reuse of energy through heat recovery. Such measures help keep energy costs at a minimum over the long term. In addition, heat recovery measures pay for themselves in a very short time due to sharply rising and continuing increases in energy prices.
When financing such energy-saving measures with external funds—for example, through equipment leasing—customers find that the savings exceed the financing payments. Customers thus obtain an energy-saving system without investing their own capital; the financing payments are covered by the savings, and the surplus savings can be used to purchase new production machinery.
Double the Energy Savings
Many plastic and metal processing companies could reduce their heating energy bills to nearly zero by using heat recovery! This system technology from ONI makes it possible to utilize waste heat from production for heating purposes. This technology is based on special heat exchangers developed by ONI that operate with a heating water temperature of just 35 °C. Today, there are series of heat recovery units available that, despite the low heating water temperature, are capable of supplying heat to industrial halls or office spaces with uniform temperature distribution.
Waste heat sources for this type of heat recovery are usually sufficiently available, particularly in plastic or metal processing plants. For example, from oil cooling in hydraulic units, which generally operate with a supply temperature of 30 °C and a return temperature of 35 °C. This type of heat recovery also has an extremely positive additional benefit. Energy paid for once to power the hydraulic drive is used a second time, via the cooling water system, for heating purposes, while simultaneously reducing the costs that would be required to operate a recooling plant. The use of heat recovery therefore results in a threefold benefit of electricity as drive energy in industrial facilities! Thus, waste heat—whose recooling costs money—is converted into heating energy through ONI’s heat recovery system, saving on heating costs!
