RadiPac stands for ...

True performance figures, because the performance data are always measured for the entire fan consisting of high-performance impeller, GreenTech EC motor and control electronics.

Effective logistics, because a single RadiPac part number covers all the components required for your ventilation application – one-stop shopping.

Easy commissioning, because all the functions required for operation are already incorporated and coordinated.

Simple and safe

Comparison conventional fans and GreenTech EC fans

Clearly superior to conventional fans (left) with additional equipment: the GreenTech EC fan (right) – quickly installed and with all features already incorporated.

The high-performance impeller is mounted directly on the rotor of the external rotor motor. This saves space and allows the entire rotating unit to be balanced in a single clamping operation.

To sum up: No expensive adjustment work on commissioning, and no grounding and shielding necessary. That’s how easy it is with plug & play.

RadiPac - Compact package

"The result is what counts" – that also applies to efficiency.

Efficiency values RadiPac

Because not just the efficiency of the individual components is what matters, but rather the result of their interaction. And that is where RadiPac excels with outstanding values.

As the impeller, motor and electronics are optimally coordinated, overall efficiency levels well in excess of 60% are obtained. A major contribution to this comes from the GreenTech EC motor with external rotor.
This is a line-operated, permanently excited synchronous motor with electronic commutation (also known as BLDC).
Its efficiency levels far surpass the requirements of efficiency class IE4, without the use of problematic rare-earth magnets. The design of other internal rotor permanent magnet motors achieving comparable efficiency makes rare-earth magnets essential. They are also less compact and less easy to install and commission on account of the external control electronics required.
