Energy savings with IE4 motors
Outstanding performance and reliability with exceptional efficiency and minimal space requirement: these are just some of the advantages that Kaeser Kompressoren's new CSD and CSDX fluid-cooled rotary screw compressors have to offer. Now equipped with IE4 motors, these future-fit machines are more efficient than ever before.
Kaeser's design for this latest generation of compressors far exceeds current norms, including the use of high efficiency IE4 motors as standard. This not only ensures that compressed air stations will meet future legal efficiency requirements, but also brings an additional energy cost saving of approximately one percent. CSD and CSDX systems therefore provide four-way energy savings: First, the airends feature newly-refined Sigma Profile rotors. Together with additional optimisation measures, such as reduced internal pressure losses, the new machines therefore boast between three and six percent better specific power performance compared with previous models. Second, the use of Super Premium Efficiency IE4 motors ensures maximum drive motor efficiency. Third, Kaeser's 1:1 direct drive system eliminates the transmission losses associated with gear or belt drive solutions. Fourth, with five pre-programmed control modes, the Sigma Control 2 industrial PC-based internal controller dynamically adjusts flow rate to match actual compressed air demand thereby assuring further energy savings.
With available motor powers from 45 to 90 kW, the five models of the two series cover flow rates from 8.3 to 16.1 m³/min (at 8.5 bar) and are designed for pressures up to 15 bar.
