Sigma Control™ Developed by Kaeser in conjunction with Siemens AG, this patented compressor control features an industrial-based PC with an Intel® microprocessor inside. Five different compressor control configurations are available to precisely match compressor performance to air demand and increase energy savings. With Sigma Control compressor systems can be monitored and adjusted from any location worldwide. Sigma Control also features extensive capabilities for maintenance trending and air demand tracking. The Sigma Profile Kaeser’s proprietary Sigma Profile airend was introduced in...

5 Lower Long-Term Costs Energy costs are a significant portion of any compressed air system’s total lifetime cost. In fact, the amount of energy required to run the compressor for just one year can exceed the compressor purchase price. Over a period of 10 years, this normally totals 70% of the overall costs. With Kaeser’s energy-saving screw compressors delivering up to 20% more air per horsepower, the cost-efficient choice is clear. Electricity Equipment Maintenance

V-Belt Drive Compressors 6 Atmospheric air is drawn through the inlet filter and valve (1) into the airend where it is compressed. The airend is driven by an electric motor (3). Synthetic cooling fluid, Sigma Premium Fluid, is injected into the airend to serve as coolant, lubricant and sealant. Under normal conditions the air reaches a temperature of about 180°F during compression. A multi-stage separator (4) removes the coolant from the compressed air and the air emerges from the separator with a remaining fluid content of less than 3 ppm. The fluid then passes through the cooler (5) , the...

One-to-One Direct Drive Compressors 8 Optimized Efficiency In Kaeser packages, one-to-one drive reduces the number of components needed compared to a gear-driven unit thus increasing reliability and service life. Kaeser has selected oversized airends specifically matched to produce the required output in flow and pressure. Compared to compressors using small, high-speed, gear-driven airends, the one-to-one drive provides triple savings: no-loss power transmission, lower power consumption, and reduced maintenance and related downtime costs. Airend Drive Motor Airend RPM = Motor RPM

The one-to-one direct drive units feature a low noise radial fan and a new “split cooling air flow” design that dramatically reduces noise levels and provides optimum cooling. Cooling air is drawn directly from ambient air, routed through the coolers and exhausted upward through the cooler box. Plus, the coolers are conveniently located on the outside of the unit so that dust and dirt build-up are easily monitored, accessed and removed without dismantling the coolers. 9 Sigma Profile airend Kaeser uses a number of newly designed airends. They are precision-machined to close tolerances and...

Sigma Frequency Control 10 Unmatched Performance Kaeser Sigma Frequency Control combines Siemens AG drive technology with our proprietary Sigma Profile airend and Sigma Control system. Our engineers have optimized airend design to accommodate a wide flow range with unmatched efficiency. Drive motor and airend operate at low rotational speeds, resulting in exceptional reliability and long life. Kaeser’s SFC units range from 8 to 515 kW and are incredibly quiet, with noise levels as low as 67 dB(A). Many SFC models are also available with integrated dryers. Integrated System Design Even...

Integrated Systems 11 Kaeser rotary screw compressors are also available in a variety of configurations. These package systems can be customized to suit your specific compressed air and clean air treatment needs. AirCenters come with integral refrigerated dryer and ASME coded receiver tank “T” Series While all Kaeser compressors are available as stand alone units, most models are also available with clean air treatment equipment built in. The “T” series rotary screw compressors feature integral refrigerated dryers with stainless steel, plate-type heat exchangers, moisture separators and...
