Sigma Profile™ airend Our single-stage, flooded rotary screw airend delivers pressures up to 217 psig and features our power saving Sigma Profile design. Our airends are precision machined and optimized in size and profile to match the airend speeds with their best specific performance. Unlike the competition, Kaeser Compressors makes many different airends so that we can apply them at their optimal speed and performance. True 1:1 direct drive In our design, the motor is directly connected to the airend with a one-to-one coupling, providing maximum transmission efficiency. This true...

Intelligent control and protection To protect your investment and ensure the most efficient operation possible, we control these compressors with our Sigma Control 2™. This intelligent controller comes standard with multiple pre-programmed control profiles so you can select the one that best fits your application. Sigma Control 2 monitors more than 20 critical operating parameters, shuts the unit down to prevent damage, and signals if immediate service is required. It also tracks preventive maintenance intervals and provides notice when PMs are due. An RFID sensor provides secure access and...

Split cooling design Two separate cooling air inlet zones for the coolers and drive motor ensure optimum cooling. Drawing ambient air directly across the coolers and motor through separate zones eliminates preheating and results in longer lubricant life and a cooler running motor. This also results in much lower approach temperatures, improving moisture separation and air quality. To increase reliability and reduce maintenance costs, the coolers are conveniently located on the outside of the unit, where dust and dirt build-up are easily seen and can be removed without dismantling...

Energy-saving control The integrated refrigerated dryer in Kaeser units provides high efficiency performance thanks to its energy-saving control. The dryer is active only when compressed air actually needs to be dried. This approach achieves the required compressed air quality with maximum efficiency. Refrigerated dryer with Eco-Drain The refrigerated dryer also features a zero loss Eco-Drain which is monitored by the Sigma Control 2. The advanced level-controlled condensate drain eliminates the compressed air losses associated with solenoid valve control. This saves energy and...

Service-friendly design The ASD, BSD, and CSD series rotary screw compressors feature an open package layout. All of the major components are easily accessible reducing preventive maintenance time by as much as 50% when compared to other similarly sized units. Additionally, there is no central column that needs to be removed to access the motor or airend. For installations where space is limited, both the front and back doors of the package fully swing out, making it possible to perform maintenance from the front or back of the package. Each door can also be removed for even more service...

The next level of energy savings The rise in energy prices is an unwelcome reality in today’s manufacturing and business environment. While the rate of price increases for natural gas, heating oil, and other sources may vary from year to year, the upward trajectory is clear. Energy cost reduction strategies are vital to staying competitive. Compressing air converts the electrical energy you pay for into heat. Our compressors are available with a heat recovery option to easily recover up to 76% of this energy. You can harness additional heat recovery by ducting exhaust air. In all, 96% of...
