Optimum performance and reliability even under the toughest of conditions


The SIGMA CONTROL 2 ensures efficient control and system monitoring. The large display and RFID reader provide easy communication and maximum security, whilst the SD-card slot greatly simplifies fault analysis tasks.
   Air-cooling reduces operating costs
Air-cooled versions are designed to meet the demands of even the toughest operating environments and can be used in ambient temperatures as high as +45°C. A combination of a stainless steel pre-cooler and an aluminium aftercooler (DSG-2, FSG-2) is installed downstream from both the low and high pressure stages. These systems also feature a gear oil cooler.
   Efficient compressed air cooling
Quiet and powerful, the radial fan draws in cool ambient air through the cooler. Its high residual thrust allows connection of long exhaust duct sections. In addition, the radial fan consumes significantly less drive power than conventional axial fans, saving even more energy.
   KAESER standstill fan
Due to the standstill fan, the large radial fan of air-cooled systems can be shut down when the compressor is in standby mode. Heat trapped in the compressor is then safely removed through the energy-saving, temperature-controlled standstill fan.
