A humming heart
Two ventilation systems, two fans that weigh over a metric ton each. Every hour, they take in around one million cubic meters of air and supply a hospital in Ulm with fresh air. The technicians and engineers were faced with the question: How can we repair the ventilation system without endangering the fresh air supply?

From one to twentyfour
The old, belt-driven fan was removed and replaced with efficient RadiPac EC centrifugal fans that form a FanGrid. Thanks to their compact design, they were able to be lifted directly into the ventilation system via an external lift, saving time and money.
FanGrid instead of a freewheel fan
Installing the FanGrid only took one day. The RadiPacs with fixing bracket are stacked on or next to each other like cubes and are then simply screwed and wired together.

Of course, the hospital saves energy thanks to the new fans, but the primary goal was to ensure safety: The FanGrid always guarantees the required air performance, a major difference compared to the old freewheel fan. And an absolutely necessity. After all, people’s health depends on it.
