To achieve high air performance in ventilation technology, several smaller fans are combined to create a FanGrid. ebm-papst now has FanGrid modules with RadiPac centrifugal fans in its product range – with automatic resonance detection for more operating reliability.
Many applications require high air performance. Data centers, large industrial building complexes, hotels, residential complexes and hospitals are all typical examples.
Cubes prevent installation loss
At ebm-papst, fans for a FanGrid are installed in a support structure. The cube has extra-generous dimensions to prevent the undesirable installation loss that arises when fans are positioned too close together and can influence each other.
Automatic resonance detection for more operating reliability
Depending on the installation situation, resonance can cause vibrations within specific speed ranges. Such vibrations can damage the bearing system of electric motors and lead to fan failure. This is why ebm-papst has developed automatic resonance detection that minimises the effects of vibration – vibration velocity – for its RadiPac centrifugal fans.
Energy-efficient EC technology with convenient closed-loop control
The driving force behind the fans installed in the fan grid are modern EC motors, which are highly energy efficient in both full- and partial load operation. The FanGrid line is rounded out by a new controller that easily activates fans operated in parallel. It requires minimal wiring work. ebm-papst FanGrid modules are available as plug and play compatible units or as complete kits consisting of the fans, air inlet grill, support plate, corner connectors and spacer profiles for direct installation on site.
Smaller, lighter, better FanGrid
In practice, FanGrids have many benefits. The individual fans can be arranged next to or above each other to save space. They significantly improve air distribution and ensure a more even airflow through upstream or downstream components such as filters or heat exchangers. Their redundancy also increases operating reliability, since the other fans compensate for missing air performance. The relevant redundancy requirements can be taken into account during the selection process.
