Kaeser DSD.3 series rotary screw compressors

Monday, 09 January, 2017 | Supplied by: Kaeser Compressors Australia


Kaeser Compressors has announced its latest generation DSD.3 series rotary screw compressors, featuring a high-performance Kaeser rotary screw compressor block equipped with the flow-optimised and energy-saving ‘Sigma Profile’ rotors.

The series boasts up to 6% better power performance compared with previous models. It includes a ‘super premium efficiency’ IE4 electric motor that complies with and exceeds prevailing Australian GEMS regulations for three-phase electric motors, while also contributing to lower energy costs. Transmission losses associated with gear or belt drive solutions are further eliminated with these 1:1 direct drive systems.

All models feature a built-in Sigma Control 2 industrial PC-based compressor controller that is responsible for dynamically adjusting the flow rate to match actual compressed air demand, thereby assuring further energy savings. Energy-saving control modes, variable communication interfaces for communication with centralised control systems and an SD card for update and backup are just some of the many features available on the Sigma Control 2.

Relevant information can be viewed at a glance from the easy-to-read display. RFID technology further assures secure login, meaning that service work and system changes to the compressor can only be performed by authorised personnel.

The sensor-controlled electronic thermal management (ETM) system dynamically controls the screw compressor block discharge temperature. The control valve actuator is controlled via signals from the Sigma Control 2 controller, which is coordinated with the oil cooler’s speed-controlled fan. For the end user, avoiding high screw compressor block discharge temperatures leads to reduced energy consumption and potentially a longer fluid service life.

The units are available air- or water-cooled, with drive power 75 to 132 kW, working pressure 5.5 to 15 bar and free air deliveries from 3.6 to 25.45 m3/min. They are available as a standard machine, with integrated refrigeration dryer and/or with Sigma Frequency Control.
