How do Kaeser screw compressors work?Atmospheric air is drawn through the inlet filter(1) into the airend(2)where it is compressed. The airend is driven by the electric
motor (3).
Synthetic cooling fluid
Sigma Premium Fluid, is injected into the airend to serve as coolant, lubricant and sealant. Under normal conditions the air reaches a temperature of only about 180°F during compression.
A three-stage separator(4) removes the cooling fluid from the compressed air. The fluid passes through the cooler(5), the microfilter(6) and back to
the point of injection. A thermostatic valve regulates and optimizes the fluid temperature. The air emerges from the separator cartridge(7) with a remaining fluid content of less than 2 ppm, passes through the
minimum pressure/check valve(8) and finally through the aftercooler (9).
In the aftercooler, the air is cooled down to around 9°F to 18°F above ambient temperature and most of the moisture is removed. The air finally leaves the compressor at the outlet (10). |
