In the Fr3200 and Fr4100 series compressor, access to internal parts is allowed by two covers positioned sidewise.
Compression process
With the single-screw compressor the suction, compression and discharge process takes place in a continuous manner
thanks to the upper satellite. In this process the suction gas penetrates into the profile between the rotor, the teeth of the
upper satellite and the compressor body. The volume is gradually reduced by compression of the refrigerant. The
compressed gas under high pressure is thus discharged into the built-in oil separator. In the oil separator, the gas/oil
mixture and the oil are collected in a cavity in the lower part of the compressor, where they are injected into the
compression mechanisms in order to guarantee compession
’s sealing and lubrication of the ball bearings.
