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 94 % 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.

Energy saving controllers SIGMA CONTROL and SIGMA CONTROL BASIC

The SIGMA CONTROL automatically regulates and monitors the compressor. It is a robust PC-based industrial computer with real-time operating system and update capability. System operating status can be viewed at a glance via user-friendly ‘traffic light’ LEDs. The four-line plain text display, touch keys and icons ensure ease of operation.
In case of an alarm the safety shutdown sequence immediately switches the compressor off. The SIGMA CONTROL offers the possibility of Dual, Quadro and Vario Control modes and the most efficient mode can be determined directly onsite using the programmable compressor duty cycle display feature.
Interfaces are provided as standard for connection of a modem, a second compressor in base load sequencing mode and for connection to data networks.

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.

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.
