Kaeser Compressors CBS series rotary screw blowers

Friday, 02 March, 2018 | Supplied by: Kaeser Compressors Australia

Kaeser Compressors has announced the CBS series of rotary screw blowers. Complementing the company’s existing range of energy-efficient screw blowers, the series brings the advantages of screw blower technology to lower flow rate applications such as those found in the wastewater treatment sector.

From bioreactors and flotation to the production of aeration air for municipal and industrial wastewater treatment plants, there are a number of applications where low-pressure compressed air with low flow rates is required. To meet these needs, Kaeser has extended its compact and turnkey range of rotary screw blowers. The CBS series of screw blowers deliver compressed air with differential pressures up to 1000 mbar, power from 7.5 to 22 kW and flow rates from 15.7 to 22.3 m3/min.

The company claims that the screw blowers offer significant energy advantages in the two-digit range compared to other screw and turbo blowers on the market, making them up to 35% more efficient compared to conventional rotary blowers. One of the models is said to be so powerful that it efficiently covers the control range of two or three rotary blowers.

This efficiency is achieved in part by the inclusion of Kaeser’s screw compressor block, which features Sigma Profile rotors. This efficient screw compressor block includes a wide control range and ensures virtually constant specific power. Even at maximum speeds, the rotors ensure minimal transmission loss. The use of high-tech bearings and no need for ancillary equipment further minimises energy consumption.

With low maintenance, energy efficiency and the ability to set up units directly adjacent to one another, the screw blowers are especially advantageous for continuous operation. Delivered ready for immediate operation, the versatile turnkey blowers are equipped with a star-delta starter (or frequency converter). They therefore save time associated with planning, installation, certification, documentation and commissioning.

For efficient blower control and system monitoring, the screw blowers come with an integrated Sigma Control 2 compressor controller. Various interfaces enable rapid communication with control centres. Where multiple blowers exist, further efficiencies can be made by integrating the Kaeser Sigma Air Manager 4.0 (SAM 4.0) master controller — the central mastermind that controls the various machines in its network for optimum efficiency, precisely matching air delivery to the required airflow. Analysing the operating data within seconds, the SAM 4.0 simulates possible responses and selects the most efficient option.
