Kaeser DN 37 C XL booster

Kaeser Compressors has announced its DN 37 C XL booster designed for applications such as PET bottle production, process air applications and nitrogen generation that require high air demand up to 25 bar.

Premium Efficiency (IE3) drive motors, equipped as standard, contribute to energy-efficient performance, as does the large axial fan, which also helps with temperature control.

The DN C series boosters also feature separate cooling air flows for the compressor block, drive motor and control cabinet, which are drawn in through openings in the right-hand side of the enclosure. Once they have been used for cooling, the separate air flows are combined and then discharged upwards through the exhaust air outlet in the top of the enclosure.

This design prevents cool inlet air from mixing with warm exhaust air, improving efficiency. Thermal overload is therefore kept to a minimum and a separate, energy-consuming cooling system for idling is only necessary under extreme conditions.

DN C series boosters are delivered as complete turnkey systems, matched to the upstream compressor. With the Sigma Control 2 controller, they are ready for connection and self-monitoring.

All maintenance-relevant components, such as cylinders and venting valves, filters, condensate separators, oil drain and filler openings are easily accessible due to large maintenance doors.
