RadiCal – centrifugal fan with EC motor.In the new RadiCal, the air performance has been increased consid-erably while retaining the existing dimensions. Its special impeller design also enables a significantly higher speed for a further increase in power density.

Maximized overall efficiency.Every new product developed must be economically and ecologically superior to its predecessor. In keeping with this philosophy, the new RadiCal boasts top efficiency values and is also optimized for envi-ronmental compatibility, a long service life and recyclability.

Lower noise.Thanks to lower flow losses in the impeller, lower turbulence and less laminar separation, the fans also have more pleasant noise charac-teristics.

The power to change.The external dimensions of the improved RadiCal centrifugal fan correspond to those of the previous model, meaning it is easy to replace. See for yourself in the following comparison. For you as the customer, that means you get an even more powerful RadiCal with the same installation dimensions.

The next level of green GreenIntelligence is the logical next step in the evolution of GreenTech. In a nutshell, it is everything GreenTech stands for, enhanced by the possibilities and opportunities of digital connectivity, the In-ternet of Things and artificial intelligence.

Steady conditions protect valuable data

Data is the new gold, and so-called precision air-conditioning units, used to cool the servers, keep it flowing freely and ensure that it gets stored safely. In data centers and network control centers, these units keep the temperature constant and maintain optimum air dis-tribution and humidity.

An indispensable part of precision air-conditioning units: the RadiCal centrifugal fan. It has been optimized specifically to ensure that air is conveyed efficiently through these devices in continuous operation. With the same compact size, it delivers significantly higher air per-formance than its predecessor, enabling optimum use of the limited space available in precision air-conditioning units – with considerably better efficiency and acoustics.

Space-saving and maintenance-free.

Increased efficiency.Its power consumption at the same air flow also shows the new RadiCal impeller’s improved efficiency when installed. For this purpose, three RadiCal fans were run in parallel in a precision air-conditioning unit, and the previous and the new version were then measured. The result: a reduction in power consumption of more than 10%.
