Advantages

Advantages

 N/A
  • Plug and play operation saves time and money - Blowers with integrated controls result in considerable savings for planning, installation, commissioning, data communication, and certification.
  • Safe and reliable conveying, optimized for your needs - Our SIGMA CONTROL 2 controller not only makes complete systems more efficient, it also continually monitors and transmits performance and status data. The result: Maximum reliability and availability.
  • Compact footprint thanks to intelligent enclosure design - COMPACT blower with sound enclosure. In the STC version, units can be installed side by side, as maintenance access is in the front and air connections are located in the back.

Low Life Cycle Costs

Low Life Cycle Costs

 N/A Our comprehensive approach to life cycle cost management: Superior efficiency, easy operation, service-friendliness, and the latest in technology to keep performance high well into the future.

Equipment

Blower Block

 N/A
  • Robust and durable
  • Energy-efficient Omega Profile rotors
  • Wide control range

Drive Motor

 N/A
  • IE3 high-efficiency motor
  • Three PTC thermistors as standard
  • Calibrated with OFC frequency controller for variable speed systems
  • Easily accessible, central lubrication port to regrease motor bearings for fast and safe maintenance

Sound Insulation

 N/A
  • The system's blower and motor cooling air is drawn in from outside the sound enclosure from the cooler ambient surroundings for maximum energy efficiency.
  • Effective sound-proofing provided by thick-walled lining with dense foam and dampening louvers over intake and exhaust openings
  • Absorption silencer minimizes process air pulsation downstream of the blower block
  • Low residual pulsation for minimal sound transfer to downstream piping.

Power Transmission

 N/A
  • High efficiency
  • V-belt guard for safe operation
  • Automatic belt tensioning for consistently high power transmission ratio
  • Belt tensioning device also serves as motor lifting device when changing the belt.

Sigma Control 2

 N/A
  • SIGMA CONTROL 2 with blower-specific software
  • Display and RFID reader provide effective communication and enhanced security.
  • Highly flexible and easily integrates into plant control / SCADA systems thanks to the multiple available interfaces
  • SD card reader for quick and easy updates and logging operating data

ACA Aftercoolers

 N/A
  • High efficiency ACA aftercoolers specially developed by KAESER for operation with rotary blowers
  • Reduction in blowing air temperature to max. 50 ºF above ambient while maintaining optimum pressure with no cooling water required
  • Electrical connection directly in the blower control cabinet.

Innovative Installation Concept

Innovative Installation Concept

 N/A To save space, multiple COMPACT blower units can be installed side by side.
  • All maintenance and installation work can be performed through the front or top of the unit.
  • All valves are mounted directly on the blower unit.
  • The pipe connections and cooling air apertures are located at the rear.
Accessible from the front -
  • Belt tensioning device and tension indicator (two-section belt guard for larger units)
  • Intake filter inspection and change
  • Motor terminal strip
  • Oil drain and filling plug, oil level inspection

Outdoor Installation - No Problem!

Outdoor Installation - No Problem!

 N/A Installing Kaeser blowers outdoors is simple and inexpensive. The specially designed shields to protect the air inlet apertures against heavy rain are equipped with a bird screen. A stainless steel roof cover also provides protection against overheating due to sun exposure.

Accessories

Start Control (STC)

 N/A Control cabinet includes: wye-delta starter (with remote operation capability), sound enclosure fan control, operating hours counter, and KAESER CONTROL (the interface to Kaeser's service facility).

Variable Frequency Control (OFC)

 N/A Frequency control enables infinite blower speed adjustment and, with the addition of a pressure sensor, also enables pressure regulation. The control unit coordinates operation of the frequency controller and the blower unit. Flexibility is further enhanced by the supplied signal output / input and Profibus connections.
