Delivering improved specific power, the flow-optimised and

further refined SIGMA PROFILE rotors provide the basis

for exceptional energy efficiency. The use of high performance

IE4 drive motors maximises energy efficiency,

whilst KAESER’s 1:1 drive design eliminates the transmission

losses associated with gear or V-belt driven systems,

since the motor directly drives the airend. Furthermore, the

radial fan fulfils the efficiency requirements for fans as per

EU directive 327/2011. Last, but not least, the advanced

SIGMA CONTROL 2 compressor controller achieves additional

energy savings and minimises cost-intensive idling

periods through the use of a variety of specially developed

control options, e.g. Dynamic control.
