Quick Overview

KAESER SIGMA FREQUENCY CONTROL (SFC) rotary screw compressors are engineered to be the foundation of your demanding industrial application. Using the latest in Siemens drive technology, KAESER SFC units are able to meet varying demand while maintaining stable pressure control. The result is exceptional reliability and superior energy efficiency. As a matter of fact, these units are up to 25% more efficient than the competition. Most compressed air systems have varying loads and it is often more effective and efficient to apply multiple compressors to meet changing demand. In cases where the demand profile changes more rapidly and frequently, variable frequency drive compressors may also be recommended. By varying the frequency of the input electricity to the motor, these compressors speed up and slow down to match their air output to your demand. Our frequency drives are the ultimate soft starter for your motor using the lowest start up current. They eliminate heat spikes in motor windings, allowing unlimited motor starts. Of course, frequency drives usually have fewer starts/stops, which means less frequent loading and unloading, for less wear and tear on important mechanical parts. KAESER’s SIGMA FREQUENCY CONTROL (SFC) units have superior part-load performance and make great trim load machines. They can be easily integrated into a multi-compressor system to provide faster response to variations in air consumption. At the same time, they can reduce electricity costs since their electrical consumption varies directly with air production. KAESER’s SFC design includes highly accurate sensors to maintain stable pressure (±1.5 psig), without wasting air by over pressurizing the system. This also increases reliability and product quality in your plant.
