Event spaces experience two extremes: they are either unused or packed with people. The ventilation system in the event location Stiftskeller in Beutelsbach could no longer cope with the changing requirements: after a retrofit, it not only circulates air more efficiently but is also vigilant about the air quality using sensors. »
Today, centrifugal fans are used in a wide range of applications. Depending on where they are installed, resonances with increased vibration velocities may occur in unforeseen speed ranges. If the fan is often operated in such critical ranges, the drive motors’ bearing system may be damaged, leading to premature fan failure. Although these vibrations are measurable for the system operator, it is not easy to stop them. Automatic resonance detection provides a remedy. It avoids operation at critical speeds, which increases the service life and operational reliability of the fans»
At some point, a huge belt-driven fan departs this life. At fiber manufacturer Cordenka, an air intake system’s fan, measuring over two meters, conked out. It was installed in a small space behind a narrow service door. The right replacement was required… and it now offers major advantages. »
Fans are complex flow machines, which sometimes respond to aerodynamic changes in their surroundings. The installation situation plays an important role here. This means that, when installed in the application, the fan is often not as quiet as hoped for, or less efficient than promised in the data sheet. Last but not least, we recommend having the fan manufacturer on board at an early stage of in-house unit development. This means there will certainly be no unpleasant surprises later.»
