Efficiency at the touch of a button
When it comes to HPC KAESER rotary screw blowers with the SIGMA Profile, efficiency is more than just a promise.
As operation-ready, “Plug-and-play” complete solutions, low-maintenance blower systems offer exceptional efficiency at the touch of a button.
What is more, KAESER rotary screw blowers are designed to be especially compact, can be controlled remotely or automatically for trouble-free operation and are compatible with Industrie 4.0 systems.
Low energy consumption, coupled with the ability to operate at 100% duty cycles, ensures that HPC KAESER rotary screw technology pays off handsomely when it comes to municipal and industrial wastewater treatment, flotation, fluidisation and fermentation applications.
Performance data:
- 7.5 kW to 250 kW
- Flow rate from 3 to 160 m³/min
- Pressure differential 300 to 1100 mbar
Your benefits:
- Maximum efficiency
KAESER rotary screw blowers are highly efficient across a broad flow rate control range. Their exceptional efficiency allows savings of up to 35% in comparison to conventional blower systems. - Operating data and status information in real-time
The integrated SIGMA CONTROL 2 controller provides efficient control and monitoring of operating data and status information in real-time. A multitude of available communications channels make conducting energy audits in accordance with ISO 50001 as easy as child's play. - Low installation costs
Connection-ready blowers are delivered complete with all sensors and an emergency stop switch, are ready-filled with oil and are fully certified. This significantly reduces the work and costs required for planning, installation, certification, documentation and commissioning.

Efficient drive systems
HPC KAESER rotary screw blowers from are now equipped with Super Premium Efficiency and Ultra Premium Efficiency motors (IE4/IE5 and IES2), which - thanks to their exceptional efficiency - are characterised by huge energy saving potential.
Saving money has never been so easy!

Optimised Specific Power
The highly efficient drive system, an extra-dense screw profile and nearly constant specific package input power across a broad, variable-speed control range (yellow line) all combine to achieve significant energy savings across the entire operating curve.
