Perfect in refrigeration technology, industrial ventilation, and telecom applications
The AxiACi series was developed for use in commercial refrigerated cabinets and also demonstrates its high flexibility and efficiency in applications from the fields of control cabinet cooling, industry, and telecommunications, where they are the perfect replacement for obsolete AC solutions.
Whatever the application, the energy-saving AxiACi series is designed to withstand the rigors of extreme environments such as temperatures ranging from +75°C to -40°C, salt spray, water jets, and dust. It is also ideally suited for use with natural refrigerants such as ammonia, propane, ethanol cyclohexane, n-butane, and others.
But that isn’t all. Its numerous certifications and wide voltage range from 90 to 264 VAC ensure top performance and maximum flexibility at all times. All over the world. And maybe even beyond…

DiaForce is our latest and most innovative diagonal compact fan, combining the high airflow volume of an axial fan with the high back pressure capabilities of a centrifugal fan. The result? The performance of a counter-rotating fan with less noise and a significant power reduction.
In today’s digitally connected world, we are storing and managing enormous amounts of data. Keeping that data safe and accessible means ensuring the infrastructure needed to support it stays at an optimized temperature. Whether in servers, autonomous technologies, artificial intelligence, or IoT solutions related to 5G, DiaForce delivers the powerful cooling needed with minimal energy consumption and noise, key considerations in this growing industry.
Counter-rotating fans, or two axial fans in series rotating in opposite directions, are often used in these applications. They are known for their high static pressure and ability to cool densely packed electronics in chassis. The electronic components restrict airflow so high pressure is needed to ensure uniform cooling throughout the enclosure. The tradeoffs are the energy consumption needed to power the fan coupled with noise. We developed an air mover that delivers the necessary static pressure but with quieter and much more efficient operation.
How did we do this? Through an aerodynamically optimized design featuring unique geometries for both the impeller and housing. The concept is revolutionary – DiaForce draws air in and blows it out both axially and radially while retaining an axial design (favorable for installation). Its cover plate is cut in a conical shape – the intake opening is smaller than the outlet opening – and rotates with it, creating a greater pressure increase than an axial fan could achieve. The blade tips pass directly into the cover plate. As a result, there is no tip gap and therefore hardly any turbulence in the gap area, where there is a considerable pressure gradient. This allows for a noticeable noise reduction.
These features combine to give DiaForce superior performance to a single-stage axial fan and lower noise than a two-stage axial (two fans placed on top of each other) or counter-rotating fan – the best of both worlds.

Particularly in IT, telecommunications, network technology, and industrial applications, highly integrated electronics require cooling that safely reaches all of the components. In some cases, conventional single-stage fans are too weak, but the installation space doesn’t allow for multiple fans.
With AxiTwin 100, two individual fans connected with an innovative flange work together by rotating in opposite/counter-rotating directions. This enables the downstream fan to convert residual swirl from the upstream fan into airflow which increases efficiency compared to individual fan solutions. As a result, AxiTwin delivers maximum performance with minimum space requirements.
