Kaeser ASD series rotary screw compressors

With free air deliveries from 3.16 to 5.53 m³/min at 8.5 bar, and capable of 15 bar maximum operating pressure, the Kaeser ASD series rotary screw compressors are suitable for users who require small volumes of compressed air.

At the heart of every ASD compressor is a Kaeser rotary screw compressor block equipped with flow-optimised Sigma Profile rotors. The compressor block and the drive motor are directly coupled and turn at exactly the same speed. The drive power is transmitted from the motor to the compressor block without the losses incurred by gearing or drive belts. The use of IE3 electrical motors contributes to additional energy savings.

The Sigma Control 2 internal controller not only enables demand-oriented performance matching and dependable monitoring, but also ensures flexibility through its numerous interfaces and innovative plug-in communication modules. Connection to energy-saving master control systems, computer networks and/or remote diagnostics and monitoring systems becomes easy. The addition of an integrated RFID reader ensures service continuity, increases security and raises service quality.

The rotary screw compressor is optionally available with an integrated refrigeration dryer and/or frequency control module, allowing the compressor system to be precisely tailored to meet the user’s exact requirements. Models featuring an integrated compressed air dryer are also equipped with a centrifugal separator and an electronic Eco Drain condensate drain, ensuring efficient condensate separation and drainage and aiding effective operation of the downstream refrigeration dryer.

The ASD series rotary screw compressors are available with drive power 18.5 to 30 kW, maximum working pressure 8.5 to 15 bar and free air delivery of 2.63 to 5.53 m³/min.
