Kaeser DSDX series rotary screw compressors

The recently redesigned DSDX series rotary screw compressors from Kaeser now feature an efficient IE4 motor. Said to be the most efficient motor available, IE4 complies with, and exceeds, prevailing Australian regulations for three-phase electric motors.

The rotary screw compressors feature an electronic Thermo Management system, which controls the oil temperature to ensure a safe and consistent differential from the dewpoint temperature. This feature also creates energy savings by preventing unnecessarily high screw compressor block discharge temperatures.

A sophisticated design and the inclusion of a 1:1 drive configuration combine to enhance the efficiency of the compressors further. The screw compressor blocks have been completely redesigned and now feature a refined Sigma Profile design. Other improvements include a redesigned inlet valve and reduced internal pressure losses, delivering improved specific power on previous models.

The updated DSDX models include an integrated Kaeser axial centrifugal separator and no-loss electronic Eco-Condensate drain. This ensures high moisture separation performance with minimal pressure loss. Condensate separation is performed with maximum reliability and energy efficiency at all times.

For optimum performance, the rotary screw compressors feature the innovative Sigma Control 2 controller. Equipped with its own web server, operational data as well as maintenance and alarm messages can be viewed from any PC running a standard internet browser, simplifying compressor operation and maintenance.

The series includes both water- and air-cooled models. Versions are also available with Sigma Frequency Control.
