Fluid-cooled rotary screw compressors

KAESER’s new fluid-cooled CSD and CSDX rotary screw compressor ranges are reportedly versatile, compact, and energy-efficient. 

With motor powers from 45 kW to 90 kW, the five models of both ranges cover free air deliveries from 8.3 to 16.1 m³/min (at 8 bar) and are designed for pressures up to 15 bar.  

The CSD and CSDX compressors are said to provide significant energy savings in four ways: CSD and CSDX units feature a large, low speed Sigma Profile airend equipped with flow-optimised rotors for superior efficiency; Kaeser rotary screw airends are powered by IE3 drive motors for maximum performance and reliability; the company’s efficient 1:1 drive design eliminates the transmission losses associated with gear or V-belt driven systems, as the motor directly drives the airend; and the newly-developed PC-based Sigma Control 2 compressor controller enables compressor performance to be precisely matched to actual air demand, creating additional energy savings. 

KAESER’s new Sigma Control 2 controller reportedly provides flexibility through its numerous interfaces and plug-in communication modules, simplifying connection to energy-saving master control systems, computer networks and/or remote diagnostics and monitoring systems, such as the company’s Teleservice facility.  

The large display located on the control panel is also said to simplify on-site communication with the system, while an SD card slot speeds up data-reading and update processes.  

The addition of an RFID reader ensures service continuity, increases security and significantly raises service quality, says Kaeser.  

The Sigma Control 2 is also responsible for monitoring of compressors, refrigeration dryers and frequency converters as available.
