How KAESER rotary screw compressors workAtmospheric 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) .
Specially developed SIGMA FLUID is injected into the airend to serve as coolant, lubricant and sealant. Under normal conditions the air reaches a temperature of only approx. 80°C during compression.
A three-stage separator (4) removes the cooling fluid from the compressed air. The fluid passes through the cooler, the micro-filter and back to the point of injection. A thermostatic valve (5) regulates and optimises the fluid temperature. The air emerges from the separator cartridge with a remaining fluid content of less than 2 mg/m³, passes through the minimum pressure check valve (6) and finally through the after-cooler (7).
In the after-cooler the air is cooled down to between 5 and 10K above ambient. Most of the moisture carried in the air condenses in the after-cooler and can then be removed in the downstream centrifugal separator. The air finally leaves the compressor at the outlet (8) . |
