HPC KAESER’s ASK Series rotary screw compressors not only deliver more air for less energy, but they also combine ease of use and maintenance-friendliness with exceptional versatility and environmentally responsible design. 

The ASK Series of rotary screw compressors are true class leaders when it comes to performance. Thanks to a redeveloped airend featuring further-optimised SIGMA PROFILE rotors and low-speed operation, the latest ASK models deliver up to 16% higher flow rates compared to their predecessors.

The ASK compressors have been designed with optimum energy efficiency in mind. Refinements to the energy-saving SIGMA PROFILE rotors - and the use of Premium Efficiency IE3 motors - have contributed significantly to the increased performance of these versatile compressors. The addition of a SIGMA CONTROL 2 controller and HPC KAESER’s unique cooling system has helped to push the boundaries of efficiency even further. 

Let's dig a bit deeper to find out why the ASK Series stands out from the crowd:

• Sigma Profile: At the heart of every ASK system lies a premium-quality airend featuring energy-saving SIGMA PROFILE rotors. HPC KAESER airends are equipped with flow-optimised rotors, which contribute significantly to the overall system’s class-leading specific package input power.
• Sigma Control 2: The internal SIGMA CONTROL 2 controller ensures efficient compressor control and monitoring at all times. The large display and RFID reader provide easy communication and maximum security. Integration into the SIGMA NETWORK is also available.
• Energy-saving IE3 motors: Every HPC KAESER ASK series rotary screw compressor features an energy-saving, Premium Efficiency IE3 drive motor.
• Energy-saving radial fan: Driven by an independent motor, the radial fan assures low compressed air discharge temperatures and provides greater cooling performance for lower energy consumption. 
• Energy-efficient add-on dryer: With its efficient scroll compressor and corrosion-resistant aluminium heat exchanger, the add-on refrigeration dryer for ASK units was designed with absolute energy efficiency in mind. Thanks to its energy-saving control, it is only activated when compressed air actually needs to be dried. As a result, the required compressed air quality is achieved with maximum energy efficiency.
• Precision pressure control: The flow rate can be adjusted within the control range according to pressure, so as to match the actual compressed air demand. As a result, working pressure is precisely maintained to within ±0.1 bar. This allows the maximum pressure to be reduced, thereby saving energy and therefore costs.

The ASK Series of rotary screw compressors from HPC KAESER are available with working pressures 5.5 to 15 bar, motor power 15 to 22 kW and free air deliveries 0.79 to 4.65 m3/min.
