คำอธิบาย

The SIGMA PET AIR system comprises five components:

1. Energy-saving rotary screw compressor

The energy-saving SIGMA-Profile was developed and optimised by KAESER KOMPRESSOREN and provides the basis for production of control and process air.

2. High efficiency booster

Booster compression ratios are kept to a minimum by precisely matching the booster to suit rotary screw compressor performance, which in-turn increases energy efficiency.

3. Class 1 compressed air quality

The SIGMA PET AIR system produces technically oil-free compressed air, whilst the oil and solid particle content is reliably kept below Class 1 limits as per ISO 8573-1.

4. Complete air receiver package

High- and low-pressure air receivers are both equipped with all necessary fittings, including an electronic condensate drain.

5. Automatic control

The KAESER CONTROL monitoring and control unit is located in the main control cabinet, which also contains the booster controller (star-delta) and fuses for all drives.
