Your customers should be able to feel that a heat pump is working, but should not be able to hear it. That is why our fans are designed with aerodynamic optimization. What's more, the perfect interplay between the impeller, motor and electronics makes our products extremely quiet. We use psychoacoustics to adjust the few noises that remain to make them seem as pleasant as possible.

Energy savings depend on each individual component. That's why we are continuously developing our products. We keep an eye on the interaction of all components in order to achieve optimum efficiency. Our state-of-the-art EC motors provide custom speed adjustment and high flexibility. All of that increases the overall efficiency of your heat pumps.

The F-Gas Regulation and, with it, the legal requirements for the gradual changeover to natural refrigerants with low global warming potential (GWP) have been in force since 2015. This has resulted in less availability and increasing costs for the existing refrigerants that have been used to date. Our large portfolio of fan solutions meets the standards for flammable refrigerants so that you are on the safe side when using them in your application.

Our comprehensive portfolio not only offers a broad range of different fans and control systems but also the entire range of tailored sizes and power sizes. Just tell us the operating point and the dimensions of your application, and you will find the perfect design-in solution for your requirements.

We operate uncompromising quality management, rely on robust materials and pay attention to durability when it comes to electronics. That's why our solutions work reliably and efficiently for many years. If something does need replacing, our products can be quickly and easily retrofitted.
