Low-pressure blowers offer greater efficiency than conventional designs
Kaeser Compressors Inc. has brought the energy-efficiency savings of its world-renowned Sigma Profile to the low-pressure world with the launch of its new line of rotary screw blower packages. The EBS and FBS series are up to 35% more efficient than conventional blower designs.
With flows from 530 to 2366 cfm, the EBS and FBS series include the same design features as Kaeser's comprehensive Com-paK blower packages—high efficiency motors, silencers, inlet filters, starters/drive, a full enclosure, an onboard controller and a full complement of sensors. These units are designed, built and tested to meet international and domestic performance and safety standards, and they are available in both STC (wye-delta start) and SFC (variable frequency drive) versions.
Models also come standard with Sigma Control 2. In addition to monitoring all onboard sensors, Sigma Control 2 includes expanded communication features. With an Ethernet port and built-in Web server, Sigma Control 2 enables remote monitoring and e-mail notifications for service and alarms. Optional industrial communication interfaces—including ModBus, Profibus, Profinet and Devicenet—are available to provide seamless integration into plant control/monitoring systems such as Kaeser's Sigma Air Manager (SAM).
