Peak performance powerhouses

THE RECENTLY launched HBS series of screw blowers from Kaeser Compressors, set a new benchmark in compressor technology for the 132 to 250 kW power range, says the company, with flow rates from 60 to 160 m³/min and differential pressures up to 1100 mbar. These powerhouses not only feature exceptional control characteristics, quiet operation, optimised footprint and low maintenance requirement – they also deliver consistently high efficiency across the entire control range.

The efficiency of the HBS screw blower remains consistent across the entire control range, not just at certain specific levels, which will make this machine an especially attractive alternative to turbo compressors. They are up to 35 percent more efficient than conventional rotary blowers and also deliver significant energy advantages compared to many screw blowers and turbo compressors available on the market, says Kaeser.

The blower block is driven by a loss-free direct drive, meaning the HBS combines highly efficient operation with a low maintenance requirement. In addition, these machines are designed for space-saving installation and exceptionally quiet operation.

A frequency converter is integrated for dynamic adjustment of the flow rate to actual demand. Moreover, the frequency converter and motor are specifically coordinated to deliver consistently optimal overall efficiency.

As assurance that the predicted high savings are actually achieved, Kaeser guarantees the power consumption per unit of flow rate (specific power consumption in kW per pro m³/h) in accordance with the narrow tolerances of ISO 1217, Annex E. “End users therefore enjoy the peace of mind that comes with ensured accuracy of the projected savings and payback periods.”

The integrated Sigma Control 2 controller ensures operational reliability and smart communication via integration into process control systems, including those with Industrie 4.0 requirements. The Sigma Air Manager 4.0 master controller is recommended for blower stations with multiple blowers as it features control and regulation algorithms specially developed for the needs of low-pressure applications. This enables even greater energy savings and simplification of automation.
