Completely replacing old ventilation systems is time-consuming and costly. The fan retrofit project at a high-rise building in Dubai shows that there is huge potential for savings with EC fans arranged in the FanGrid and a demand-based control system.»
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.»
After a retrofit, a FanGrid is in operation at Changi Airport in Singapore. This is good news, not only for the operators, but also the travelers.»
The ZeitHaus museum in the heart of the Autostadt (car city) in Wolfsburg is a place that motorists long to see. On five floors of the exhibition area, there are row after row of vehicles – each more fascinating than the last. Retrofitting the ventilation ensures the right atmosphere for people and cars.»
One day, the ventilation system in a Neckarsulm shopping center just gave up. Repairing it was not an option. Facility manager Peter Halblaub had to find a solution. He decided on a FanGrid – and building technician Wolfgang Stickel stacked one RadiPac fan on top of another.»
Elsdorfer Molkerei und Feinkost GmbH replaced the fans in the ventilation system of their high-bay warehouse. The personnel were impressed by the efficiency and operational reliability of the new FanGrids.»
Quieter, more efficient, requiring less maintenance – those were the demands of packaging giant Polyplex for its new ventilation system. And it found the solution in the form of an ebm-papst FanGrid with EC fans.»
The electronics specialist Semikron wants to start the year 2020 with a new ventilation system. To ensure that this works, the installers from Kratschmayer are putting in extra shifts. The story of a retrofit between the years.»
Swire Properties wants its buildings to be green, modern, and full of variety. The real estate developer is focusing on sustainability when choosing an air conditioning system for Taikoo Place, its futuristic commercial building complex in Hong Kong.»
Futuristic architecture, musical superlatives, clever ventilation: In the concert hall in Ventspils, Latvia, music students rehearse in the best conditions.»
32 compact fans instead of two big ones: After almost 30 years, the Bombardier Arena in Sweden was in need of a retrofit.»
The trend toward huge logistics centers presents new challenges for air conditioning systems. And another important criterion for the online mail order company Zalando is data acquisition. In just under a year, the online mail order fashion company Zalando erected a logistics center in Lahr with 130,000 square meters of floor space.»
Following a motor bearing failure in the air supply system at the Media Markt store in Berlin’s Wedding district, Daume GmbH convinced the store’s management to invest in the future – with a FanGrid.»
