PRESS RELEASE Energy-efficient fans from ebm-papst Retrofit - the right way! If ventilation and refrigeration systems have been running for several years, it is worth taking a close look at how efficient they are. Upgrades with modern EC fans from ebm-papst have many advantages, especially when they are well thought through and implemented correctly. But what makes a retrofit a success? If a ventilation system is around 15 years old or the requirements for it increase, the operator must either completely replace it or retrofit more efficient fans. In many cases, a lack of space means it is not possible to replace the entire ventilation system. It can also be both very timeconsuming and expensive to do so. This is where retrofits come into play. New fans not only save energy, but also make existing systems more durable and quieter: Energy savings of 60-70 % and amortization periods of 2-3 years are attainable on average.

If you rely solely on the manufacturer’s specifications or previous measuring logs, you will often find that they no longer correspond to the system’s current application and are, therefore, not precise enough. This can lead to an error tolerance of up to 20 %. In addition to the building’s surroundings - on the coast there are different temperatures, humidity, air pressure and density than in the mountains - questions regarding electronic actuation, interfaces, mains supply and conversion measures on the air duct must be clarified. Then it's time to select the fans. Regulated as needed, extremely efficient Energy-efficient EC centrifugal fans from the ebm-papst RadiPac series are ideal for ventilation retrofits. They are particularly durable and their speed can be individually regulated as required. Only the power that is really needed is called up - for example from maximum power during the day to just 20 % power at night. If several small fans are installed in parallel in a space-saving fan wall, known as a FanGrid, they will be easier to install and maintain. This configuration also protects the system against failures because if there are problems with one fan, the others compensate for its power. If they are additionally equipped with integrated resonance detection, they will also be unaffected by critical vibration resonances in FanGrids. Since the fans are direct-drive fans without belts, there is no abrasion, which means the system remains clean and ensures higher air quality. Together with the precise temperature control, this also boosts the wellbeing of people who work or spend their free time in the buildings. ebm-papst Mulfingen GmbH & Co.
