Now, after the successful market launch of the HyBlade axial fans, the energy-efficient "RadiCal" fans from ebm-papst are defining new standards in the centrifugal field of ventilation and air-conditioning technology.

Like the HyBlades the fan blades of the RadiCal centrifugal fans are designed with a dimensionally stable, hybrid construction. Their aerodynamically optimized shape reduces noise by 50%. The motors of these fans have been miniaturized, making them much more compact than their predecessors. With these current dimensions, an easy mechanical replacement of existing AC solutions is possible any time and without a hitch.

The design of the motor heat management system is also optimized. The stator is completely encapsulated in a high-performance plastic. Air inlets in the rotor guarantee perfected heat dissipation for the motor, which in turn increases efficiency considerably. The high level of IP protection allows these fans to be implemented in critical applications.

In terms of efficiency, the RadiCal centrifugal fans already surpass the new ErP Directives for electrically powered fans. With these, up to 50% less energy consumption can be achieved in comparison to AC solutions, with the noise behavior decreased by one-half.

The good dampening behavior of the plastic also helps to reduce noise emissions. Even without special varnish, the impellers are highly corrosion-resistant, for example if exposed to salt water or salty air. Direct solar radiation has no damaging effects on the UV-resistant material.

The new centrifugal fans are currently available in sizes 133 to 250 with drive outputs between 35 and 170 W and in size 500 with three different EC motors with drive outputs of 500 W, 1 kW and 3 kW. This opens up possible applications in many areas of ventilation and air-conditioning technology, such as in control cabinet cooling, in-line duct fans, home ventilation units or heat pumps. In all of these applications, it pays off to switch to high-efficiency RadiCal centrifugal fans or to take advantage of this state-of-the-art, energy-saving technology from the start.
