These versatile rotary screw compressor ranges
provide signifi cant energy savings in four ways:
Firstly, low speed SIGMA PROFILE airends equipped
with fl ow-optimised rotors have enabled specifi c
power to be reduced by up to six percent compared
with previous models. Secondly, the use of IE3 drive
motors maximises energy effi ciency (use of these
motors became mandatory in the EU from the 1st of
January 2015). Thirdly, KAESER’s 1:1 drive design
eliminates the transmission losses associated with
gear or V-belt driven systems, as the motor directly
drives the airend. Fourthly, the SIGMA CONTROL 2
compressor controller enables compressor performance
to be precisely matched to actual air demand
thereby allowing additional energy savings.
