Kaeser Compressors
About
Kaeser Compressors, founded in 1919 in Coburg, Germany and family-owned with approximately 8,000 employees and EUR 1.6 billion in annual revenue, manufactures compressed air systems and industrial blowers for applications including wastewater aeration, pneumatic conveying, and fermentation. The company's US headquarters is in Fredericksburg, VA, and its products serve 140-plus countries through a global distribution network. For the water and wastewater market, Kaeser offers three distinct blower technologies: rotary screw blowers (DBS, EBS, and FBS series delivering up to 5,650 cfm with SIGMA Profile rotors for energy-efficient aeration), rotary lobe blowers using efficient tri-lobe OMEGA-profile rotors (28 to 5,509 cfm at up to 15 psig, a cost-effective choice for steady-state applications), and the PillAerator magnetic-bearing turbo blower (available in 200 hp and 400 hp models up to 9,240 cfm with oil-free, frictionless permanent-magnet motors and unlimited start capability). All blower lines integrate with SIGMA CONTROL 2 intelligent controllers supporting EtherNet/IP, Modbus TCP, and Profibus SCADA connectivity. Kaeser differentiates with fully packaged, factory-tested Com-paK blower systems and custom-engineered blower room installations. The SIGMA AIR MANAGER multi-unit controller optimizes blower station output to match real-time process demand, which the company notes is critical since aeration represents 50 to 70 percent of a wastewater facility's total energy consumption. Additional offerings include SmartPipe aluminum piping for corrosion-free air distribution, compressed air treatment equipment (refrigeration and desiccant dryers, filters), condensate management systems, MOBILAIR portable compressors (60 to 1,600 cfm), and the SIGMA AIR UTILITY compressed-air-as-a-service contracting model.
