Optimum performance and reliability even under the toughest of conditions
| ||Sigma Control 2|
The Sigma Control 2 ensures efficient control and system monitoring. The large display and RFID reader provide easy communication and maximum security, while 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 +115°F. 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.
| ||Energy-saving interior ventilation|
When the large radial fan in air-cooled oil-free compressors is switched off as part of the transition to standby mode, this energy-saving, temperature-controlled standstill fan reliably removes the remaining heat in the compressor package.
