Kaeser launches compact and efficient boosters

 Kaeser recently launched its completely redesigned range of boosters. With drive powers ranging from 22 to 45kW, the new DNC series boosters from Kaeser are designed for applications that require high-pressure air such as; PET bottle production, process air applications and nitrogen generation.
 
Half the size of its predecessor, the new DNC series boosters have a small footprint for where space is at a premium. Optimised for low vibration and low noise emissions, these compact units also run noticeably quieter thanks to an enclosure with integrated after-cooling as well as a low-vibration basic structure.
 
The DNC series boosters are available with Sigma Frequency Control (SFC). Incorporating a variable speed drive ensures superior harmonisation of the booster on the input side with the upstream compressor output. 

This in turn allows for the reduction of the relatively high switching frequency characteristic of some booster applications. The powerful SFC functionality helps adjust the free air delivery as consistently as possible to meet the needs of the system. This reduces switching differentials on both sides, as well as potentially resulting overpressure, leaks and machine load – all of which contribute to energy savings.
  
The boosters also include an integrated Sigma Control 2 controller, equipped with special booster software, to ensure optimal system operation whilst also enabling convenient connection to master controller systems via Ethernet. 

Since all individual components can be coordinated with one another, the entire station can be optimised to provide maximum efficiency and performance.
