- the dehumidification unit 6 includes an evaporator unit 15 of the compression refrigerating machine 11 , the evaporator unit 15 being accommodated in the condensation space 12 and acting as a dehumidification unit 6 .
- the fan unit 5 is provided above the gas treatment room 8 between the condensation room 12 and the gas treatment room 8 .
- the heating device 7 includes a condenser unit 16 of the compression refrigeration machine 11, which gives off heat to the cooled, dry gas G via heat exchanger surfaces that are approximately 60 degrees warm and heats it.
- the liquefier unit 16 is arranged in the gas treatment space 8 .
- a compressor element 17 embodied as a compressor or compressor 18 of the compression refrigerating machine 11 is arranged in the gas treatment chamber 8 .
- the heating device 7 includes in addition to the
- Condenser unit 16 preferably has an electric heater 19 with a temperature limiter 26, which is arranged in the gas treatment chamber 8. After flowing past the heating device 7, the gas G has a target temperature of approximately 33 degrees Celsius.
- a condensate collection tray 20 is present in the condensation space 12 . According to Kl, a condensate collected on the inclined condensate collecting tray 20 reaches a channel 21 with a deflection K2 and from there into a subsequent condensate discharge line 22 (see FIG. 3), for example in a flexible hose opens into a condensate collecting tank 23 .
- hollow suspension sockets 24 and hollow bracket hangers 27 are present in the receiving space 4 .
- the suspension sockets 24 are attached to the partition 9 or the front or inner rear wall between the receiving space 4 and the gas treatment space 8 .
- the fan unit 5 and flow paths for the gas G in the cabinet 3 are coordinated in such a way that the gas G in the accommodation space 4 flows in the vertical direction upwards according to S4 towards the condensation space 12 .
- the gas G flows vertically downwards in the gas treatment chamber 8 according to S2, then into the receiving chamber 4, from there according to S1 into the condensation chamber 12 and further by means of the fan unit 5 back into the gas treatment chamber 8.
