Pure efficiency with the SIGMA PROFILE Developed in the early 1970s, KAESER’s SIGMA PROFILE rotor technology revolutionised rotary screw compressor energy efficiency. Continually refined ever since at KAESER’s Research and Development Centres in Coburg and Gera, this high- efficiency compressor technology is now available for use in blower systems as well. Blower airend with SIGMA PROFILE Dependable seals KAESER’s high-efficiency blower airends combine a wide control range with near constant specific package input power. Equipped with energy-efficient SIGMA PROFILE rotors, they ensure maximum...

Direct drive – Ultimate efficiency Pure efficiency with synchronous reluctance motors In CBS to GBS series rotary screw blowers, power is transferred from the motor to the blower airend via a lossless and maintenance-free gear transmission. This has proven to be the best solution for the prevailing speeds in this performance and size class when it comes to efficiency, reliability and durability. With high-performance frequency converter As a slip-free motor, this design combines all the benefits of high-efficiency permanent-magnet motors with those of robust, maintenance-friendly asynchronous...

Efficient and dependable The blower airend plays a key role in ensuring outstanding energy efficiency. It achieves this thanks to a combination of precisely matched components and the advanced control provided by the SIGMA CONTROL 2 blower controller. Comprehensive sensors The SIGMA CONTROL 2 ensures efficient blower control and monitoring at all times. A readout display, RFID reader and numerous interfaces enable fast and reliable communication, whilst the SD card slot makes data storage and software updates a breeze. In the event of a failure of the master control system, the blower will switch...

Plug-and-play KAESER rotary screw blowers are delivered as turnkey complete machines, which saves operators a time-consuming and cost-intensive installation procedure. Moreover, they are supplied ex works ready for integration into Industrie 4.0 applications. SIGMA FREQUENCY CONTROL (SFC) The version with integrated star-delta starter for constant- speed operation is equipped with a premium contactor, overcurrent relay and phase monitoring. A SIGMA CONTROL 2 controller and dependable emergency stop system complete the package (not available with HBS). Using variable speed control, the SFC frequency...

A new standard for the low pressure segment More compressed air for less energy KAESER’s innovative CBS, DBS, EBS and FBS series rotary screw blowers not only impress with their energy-saving drive concept, but also with their well thought-out and compact design, which allows all maintenance work to be performed from the front. Side-by-side installation is possible even with all electrical equipment. Because they provide even more power and are therefore larger, GBS and HBS systems require more installation space. A certain minimum clearance is consequently required to ensure sufficient service...
