The new ASD.4 Brochure is now available for download. The ASD.4, direct drive (1:1) series ranges from 18.5kW to 30kW (3.16 – 6.17 m³/min)
KAESER pushes the boundaries of compressed air efficiency once again with its latest generation of ASD (ASD.4) series rotary screw compressors. Not only do these optimised ASD compressors deliver more compressed air for less energy, but they also combine ease of use and maintenance with exceptional versatility and environmentally responsible design.
ASD – Multiple savings
The newly refined ASD systems save energy in multiple ways: the compressor airends feature further refined SIGMA PROFILE rotors and are controlled and monitored via the industrial-PC-based SIGMA CONTROL 2 compressor controller. This advanced controller matches compressed air delivery to actual demand and uses dynamic control to keep costly idling time to an absolute minimum.
Variable speed with reluctance motor
The new synchronous reluctance motor combines the advantages of asynchronous and synchronous motors in one drive system. The motor contains no aluminium, copper or expensive rare earth magnets, which makes the drive durable and service-friendly. In addition, the functional principle keeps heat losses in the motor to a minimum, resulting in significantly lower bearing temperatures. This ensures significantly extended bearing and motor service life. In conjunction with the perfectly matched frequency converter, the synchronous reluctance motor also delivers superior performance compared to an asynchronous motor when it comes to losses, especially in the partial
load range.
Synchronous reluctance motor in Variable Speed Rotary Screw Air Compressors
Kaeser compressed air equipment is designed and engineered with the quality and forethought required to meet the demands of today’s rigorous manufacturing and industrial applications. Kaeser’s range of ASD.4 Rotary screw compressors are the perfect partners for high efficiency, industrial compressed air stations.
