More air, more savings...

 

Lower life-cycle costs

Energy costs taken over the lifetime of any compressor add up to many times that of the initial capital cost, which can make any purchase price difference a false economy. Efficiency and reliability are vital in the production of compressed air and KAESER achieves these objectives with quality, durable components that are built to last. Energy saving KAESER rotary screw compressors can help businesses enhance their competitive edge and significantly reduce compressed air costs..

Benefit the environment and save costs with heat recovery:
The waste heat generated during compressed air production represents a consider-able potential saving, since 100 percent of the energy fed to a compressor is converted into heat. This is energy that can be utilised. In fact, up to 96 % of the energy that is used to produce compressed air remains available for reuse. This not only enables huge annual financial savings, but also helps to considerably reduce CO2-emissions.
The scale of the savings effect depends on the size of the compressors and the primary energy source that is used (electricity, gas, fuel oil). Moreover, many older compressor models can even be retrofitted to provide heat recovery.

Sigma Control

Energy saving controllers:
SIGMA CONTROL 2 and SIGMA CONTROL BASIC

The SIGMA CONTROL 2 features a highly flexible modular design, yet its standard construction means that this versatile control system can be matched to suit the needs of any rotary screw compressor from KAESER KOMPRESSOREN's extensive range. Comprising a main control unit and separate input/output modules, this modular concept therefore enhances communication and user-friendliness.

Integrated web server
The SIGMA CONTROL 2 is equipped with its own web server, making it possible to communicate with the compressor via intranet/Internet. Operational data and maintenance and alarm messages can therefore be viewed, with password protection, from any PC running a standard Internet browser. This feature consequently simplifies operation and maintenance for example.

Energy-saving compressor airend with SIGMA PROFILE rotors

A specific drive power can be used to turn a smaller airend at high speed or a larger airend at slow speed. Larger, lower speed airends are more efficient and deliver more compressed air for the same drive power.
This is why KAESER manufactures low speed airends with optimised rotor profiles. Every KAESER rotary screw compressor quickly pays for itself through significant savings in energy costs.

Sigma Profil

The KAESER SIGMA PROFILE

Developed by KAESER and continually enhanced ever since, the KAESER SIGMA PROFILE brings power savings of up to 15 percent compared with conventional screw airend rotor profiles.
All KAESER rotary screw airends feature this energy-saving rotor profile and are designed to ensure maximum energy-efficiency.
The generously-sized, precision-aligned roller bearings and close-tolerance machining guarantee long service life and outstanding reliability.
