More Compressed Air for Less Energy

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 a compressor for just one year can exceed the compressor purchase price.  Over a period of 10 years, energy normally totals 70% of the overall costs. 

Since Kaeser's energy-saving screw compressors deliver up to 20% more air per kilowatt, the cost-efficient choice is clear.

The Revolutionary Sigma Control

Sigma Control automatically regulates and monitors the compressor. It is an industrial-based PC with a real-time operating system.  Easy-to-understand, color-coded LEDs indicate operating status.  The four-line, plain-text display with touch keys and menu-guided screens offer clear function choices.

The Energy-saving Sigma Profile Airend

Larger, slower-running airends are more efficient and deliver more compressed air for the same input power. Kaeser's Sigma Profile airends are optimized and designed to operate at the lowest possible speeds. Every Kaeser rotary screw compressor is equipped with a highly efficient airend and will quickly pay for itself through power cost savings.

The Proprietary Sigma Profile

Kaeser's proprietary Sigma Profile airend was introduced in 1975.  It is up to 20% more efficient than conventional rotary screw designs, offering more compressed air per kilowatt.

Efficiency and reliability are designed into the Sigma Profile airend with excellent airend inlet flow characteristics and a five-to-six lobe, assymmetrical design.  Kaeser also uses precision-aligned, high-quality roller bearings designed to withstand the most demanding conditions and extend service life.

Kaeser continues to refine and improve the airend design, and as a result, the optimized Sigma Profile airends offer unparalleled performance.
