Mid-Sized Models 18 - 110 kW
KAESER’s ASD, BSD, CSD, and CSD(X) series rotary screw compressors are engineered for energy-efficient, reliable compressed air supply across industrial applications. With options including integrated dryers, variable-speed drives, and advanced motor technologies, these systems are highly configurable to meet specific flow, pressure, and efficiency requirements. They also integrate seamlessly into intelligent compressed air management systems like SIGMA AIR MANAGER 4.0.
- Available configurations:
- Base models – standard high-efficiency fixed-speed
- T models – with integrated refrigeration dryer
- SFC models – with variable-speed drive (VSD) for optimal control
- T SFC models – with both integrated dryer and VSD
- CSD(X) models – advanced package with maximum efficiency and multiple pressure variants
- Motor types:
- IE4 asynchronous motors (fixed-speed)
- IE5 motors (VSD models)
- Synchronous reluctance motors (for enhanced partial-load efficiency)
- Energy recovery: Up to 96% of input energy recoverable as usable heat
- Cooling control: Frequency-controlled fans and Electronic Thermo Management (ETM)
- Connectivity: SIGMA CONTROL 2 and SIGMA AIR MANAGER 4.0 compatible
- Efficiency ratings:
- Fixed-speed: IE4
- VSD models: IES2 (per IEC 61800-9)
- Pressure variants: Six options available in CSD(X) series for precise system matching
