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. Find out more about the possibilities for utilizing waste heat in your business—free of charge and with no obligation!
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.
