Efficient KAESER V-belt drive

KAESER screw compressors with V-belt drive provide outstanding efficiency and reliability. KAESER was one of the first compressor manufacturers to introduce the V-belt drive system. The KAESER drive is characterised by an automatic tensioning device that ensures constant transmission efficiency and reduced maintenance costs. SX series models are equipped with a flat drive belt that does not require additional tensioning.

Save energy with the KAESER SIGMA PROFILE
Every KAESER rotary screw airend is equipped with energy-saving SIGMA PROFILE rotors. Components manufactured to the highest standards and precision aligned roller-bearings ensure long service life with maximum reliability.

SIGMA CONTROL
The SIGMA CONTROL compressor controller is a robust PC-based industrial computer with a real-time operating system and update / network capability. This advanced controller is equipped with a pressure-to-frequency profile that guarantees maximum flexibility for air delivery and pressure whilst providing best possible efficiency. Furthermore, the SIGMA CONTROL is able to communicate with other master air management systems such as the SIGMA AIR MANAGER.

Automatic belt tensioning
The automatic belt tensioning device ensures consistent transmission efficiency and excellent drive-system reliability.
(Not required for SX series)

Cooling air filter mats
Ambient air used for cooling is contaminated to some degree, but the filter mats through which the air is drawn into the cabinet prevent the cooler from clogging.

Optimised separation system
The combination of optimum flow separation and the special separator cartridge results in a minimal fluid content of less than 2 mg/m³ in the discharged compressed air. The separator system also requires very little maintenance.
(SX series models feature an external separator cartridge)
