Kaeser CBS series screw blowers

Kaeser has extended its compact and turnkey range of rotary screw blowers. The CBS series delivers 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 screw blowers are said to offer significant energy advantages in the two-digit range, with one of the screw blowers said to efficiently cover 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 its Sigma Profile rotors. This screw compressor block includes a wide control range and ensures virtually constant specific power. Even at maximum speeds, the rotors ensure minimal transmission loss. In addition, 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 advantageous for continuous operation. Delivered ready for immediate operation, the turnkey blowers are equipped with a star-delta starter or frequency converter.

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.
