Special Fans

All Dietz radial fans are modern, compact and highly stable in design. But some application situations are so unusual that they make special and challenging demands on the ventilation system. To ensure that Dietz fans maintain their customary stability and guarantee seal-tight operation even in these extreme circumstances, customer-specific designs may be required. Caustic environments, extremely high temperatures, highly corrosive or abrasive media, potentially explosive atmospheres – the customized application-specific fans we offer carry on doing their job with outstanding efficiency even under the most extreme conditions. We can comply with individual requirements not only on the inside but on the outside too: your customized fan can be supplied in the color of your choice. Particularly in demand for cleaning applications, and in process, clean room and environmental technology applications.


(F)DW Liquid cooled motors

Our liquid cooled motors provide maximum power density coupled with a very compact design. Moreover, our liquid cooled motors are used in applications, where heat emission from the motor must be avoided. The cooling medium, e.g. water or oil, can be adopted specifically to customer requirements. Motors are designed in a way that contact from cooling medium with electrical components is avoided by all means. The stator housing is designed with a smooth surface, which makes it suitable for applications in the textile industry or food industry as dust or fibers do not adhere to the surface and simplifies cleaning. For many applications, there is an increasing demand for variable speed motors controlled by frequency inverter. We use the best components and provide thoroughly constructed motors also for these applications. For use as generators, we offer specifically optimized designs.

(D)DR/(F)DP Air cooled motors

This Dietz-system motor offers a high level of variability, which makes it suitable for many different applications. We offer a wide range of different mounting flanges, brake systems, encoder systems, external ventilation and temperature monitoring systems. Furthermore, individual modifications are possible for very specific requirements. Compared to the relevant IEC-standards higher power density and higher power reserves can be achieved. Beyond the current standards IE2 and IE3 our motors are also available with efficiency class IE4. For use as a generator, we offer a range of specifically optimized designs.

Special Drives

“High-speed motors”, “Testbench motors”, “Smooth bodied motors” are only a few examples of solutions for specific customer requirements. For many fields of industry and many applications motors off the shelf will no longer be adequate.
Highly integrated plants and machines call for specialized drive concepts. In order to meet these requirements, we have concentrated our efforts in this area with a high level of competence in design, development, and production.
With our expertise and experience in power transmission, we are in the position to manage special demands from our customers.
