Screw compressors with superior efficiency

Kaeser's direct drive rotary screw compressors range from 25 hp - 650 hp and deliver outstanding performance. Kaeser uses oversized airends specifically selected to produce the required output in flow and pressure. Compared to compressors using small, high speed, gear-driven airends, the one-to-one drive provides significant savings. With Kaeser's one-to-one drive, the airend is directly connected to the motor via a maintenance-free coupling that eliminates transmission losses.

Advantages

Advantages

N/A
  • Exceptional efficiency - IE3 and IE4 motors with premium efficiency performance provide additional energy savings.
  • Longer service life - Electronic thermal management dynamically controls the fluid temperature of our ASD - HSD series for increased energy efficiency. The ETM prevents internal condensation build up, eliminating a common cause of lubricant degradation.
