Go for no. 1 
with RadiCal 2

The best in its class. 

The RadiCal series has been designed for minimum energy consumption and top performance. To ensure that applications in ventilation and air-conditioning technology continue to benefit from these strengths in future, the entire series has been further developed. The result is a new RadiCal generation that is more economical, more powerful, and more flexible than ever before.

Discover the new champion: the 2nd generation of RadiCal centrifugal fans.

Radical 2. The new no. 1 in efficiency.

Radical 2. The new no. 1 in efficiency.

Improved aerodynamics and compact design mean that the power consumption of the size 190 RadiCal 2 is 29 watts lower than its predecessor at the same operating point (525 m³/h at 550 Pa). For you, this means an energy saving of 17%. 

Radical 2. The new no. 1 in noise behavior.

Radical 2. The new no. 1 in noise behavior.

Thanks to its optimized flow control, the RadiCal 2 with its innovative blade geometry is a full 3 dB(A) quieter in size 190. And that’s despite the fact that it can handle more air than its predecessor in the same size.

The new RadiCal 2 has more power than its predecessor with the same dimensions. As a result, you may well be able to get by with a smaller size for your application than before – thereby saving valuable installation space. Why not find out?

All the advantages at a glance 

  • Enlarged intake diameter for higher filling level
  • Rounded blade inlet edges for optimized noise behavior
  • Rounded blade outlet edges for low-loss air flow
  • Wavy cover plate for minimum air flow disturbance
  • Profiled housing struts

  • Greater efficiency
  • Reduced bearing currents
  • Improved EMC behavior
  • Enhanced tightness
  • Lower noise

  • Reduces noise even with symmetrical inflow
  • Unmodified air performance and low power consumption
  • Integrated guard grill
  • Easy to install

Possible areas of application


Electronic control cabinets

The increase in air flow means that even a smaller size can achieve the desired air performance. This saves valuable installation space.

Heat pumps

Due to the redesigned impeller and module, there is less turbulence and consequently up to 3 dB(A) less noise.
