Efficient Drive, Controls and Cooling Systems


   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.
Compressor motor   Premium efficiency drive motor

Premium effiicency TEFC motors with class F insulation for extra protection from heat and contaminants. Remote grease fittings make maintenance a breeze.

   Reliable operation even in extreme heat
Air-cooled units can operate dependably in ambient temperatures up to 115°F thanks to the durable and energy-efficient radial fan.
   Parallel heat exchanger
Both the low and high pressure stages of water-cooled Kaeser oil-free rotary screw compressors are equipped with their own dedicated parallel heat exchanger for enhanced heat transfer. This optimized cooling improves specific power performance.
   Dependable oil reservoir ventilation
The micro filter in the oil tank ventilation system prevents intake of oil-laden air. This is a key detail to ensure that compressed air quality is reliably maintained at all times.
   Optimized water cooling
Water-cooled compressors feature highly efficient air / water heat exchangers. CuNi10Fe cooling pipes with internal star lamella fins provide optimum heat transfer and the lowest possible compressed air discharge temperatures with minimal pressure loss.
