Lower life-cycle costs

Purchase price and service expenses amount to only a minor part of a compressor's life-cycle costs
By far the major part of a rotary screw compressor's overall costs is the cost of electricity, which adds up to a multiple of the compressor's purchase price over its operational life.
Energy-saving KAESER rotary screw compressors can help users to curb their compressed air costs costs significantly.

SIGMA CONTROL and SIGMA CONTROL BASIC- the energy-saving controllers

SIGMA CONTROL automatically regulates and monitors the compressor. It is based on a robust industrial computer with real time operating system and update capability. Operating status is swiftly and clearly displayed by 'traffic light' LEDs. The four-line plain text display, touch keys and pictograms greatly simplify operation.

the SIGMA PROFILE

Larger, slower running airends are more efficient and deliver more compressed air for the same drive power. This is why KAESER builds airends with the slowest drive speeds possible and optimised screw profiles. Every KAESER rotary screw compressor equipped with one of these highly efficient airends quickly pays for itself through power cost savings

Sigma Profil

The KAESER SIGMA PROFILE

The KAESER SIGMA PROFILE, introduced in 1975 and continually developed, brings power savings of up to 15 percent over conventional rotary screw profiles.
All KAESER airends are equipped with rotors having this energy-saving profile. They are operated at their best specific working point to ensure highest energy-efficiency.
The generously-sized, precision-aligned roller bearings and close-tolerance machining guarantee long life cycles and outstanding reliability.

Information technology - globally networked

Modern air systems must meet up to the multiple requirements of industry. Safety, reliability, low power consumption and minimum servicing are of first priority when the air needed for the job is to be produced in the volume required at the right quality.
Normally, in an air system, the 'concerted action' of several compressors and treatment equipment has to be coordinated, whereby special attention should be paid to the interplay of the compressors because this is where most of the energy savings are made. Such complex tasks are no longer manageable by simple, conventional sequencers or base load sequencers. In such cases the capability of intelligent computers is needed. Not only do they have to turn individual compressor soloists into an ensemble and conduct them in as energy-saving a way as possible, they have to resolve futuristic tasks such as compressed air management and compressed air cost management as well - not forgetting communication.

Pure innovation - SIGMA AIR MANAGER

The Sigma Air Manager is the world's first master controller of compressed air systems that combines the advantages offered by modern industrial computers and internet technology.
Sigma Air Manager combines energy-saving, demand-related pressure band control with clear-cut visual presentation of operational data in a way that is unique and unheard of until today. Further cost reduction is achieved by advantages inherent in Internet and Teleservice links.
