Screw heat exchanger – your solution as a cooling screw or heating screw
Our screw heat exchangers, used as cooling or heating screws, are an innovative solution for the efficient temperature control and transportation of bulk materials and slurries. They combine the functions of a classic conveying system with additional process engineering processes that can be integrated directly into the transportation process. This makes them an extremely versatile and valuable component for a wide range of industrial applications.
Versatile application options for cooling screws & heating screws
Screw heat exchangers are used in numerous industries as they can combine various tasks in a single system. Whether as a cooling screw for targeted temperature control or as a heating screw for uniform heating, this technology offers far-reaching benefits for companies that rely on precise control of temperature processes.
A key advantage is the ability to combine several processes in a single step. In addition to pure transport, screw heat exchangers can take on additional functions such as dosing, drying, mixing or hygienizing. This means that companies using this technology can significantly optimize their production processes while saving on costs for additional machines or process steps.

Advantages of screw heat exchanger technology
The decision to use screw heat exchangers brings numerous operational advantages:
- Energy efficiency: The heat transfer makes optimum use of the energy required, which can reduce operating costs.
- Compact design: Compared to separate conveyor systems and heat exchangers, screw heat exchangers take up less space and enable space-saving integration into existing systems.
- Reduction of production steps: As several processes can be combined in one device, the total number of machines required is reduced. This simplifies production processes and reduces maintenance costs.
- High process reliability: The precise controllability of temperatures ensures that processes are stable and reliable.
- Adaptability: Screw heat exchangers can be flexibly adapted to specific requirements.
- Long service life: Thanks to robust materials and sophisticated technology, screw heat exchangers are extremely durable and resistant.
