3.2 Product description
The DUFTDOS-AK is used for the aromatisation of tepidaria, caldaria, infra-red cabins, ice cabins, etc., with
power control. The DUFTDOS-AK is suitable for cabins with a temperature of up to 50°C and a volume of
50 m³. The volume depends on the air exchange rate. High air exchange rates reduce the effect; moreover,
the aroma development strongly depends on the quality of the fragrance concentrate. The DUFTDOS-AK
control unit is operated via a five-line display with three sensor keys.
A small compressor blows air across the surface of a container filled with fragrance concentrate. The fra-
grance concentrate evaporates and is carried into the cabin along with the air via a 6x1 mm hose line and
an inlet nozzle. The fragrance intensity is set via the software with dosing and pause time.
Depending on the device type (AK1 –AK2) and optional device equipment, the operation and installation
of the device may differ.
Optionally, the DUFTDOS-AK can be controlled with a push button from the cabin or from an external
location via a potential-free contact.
For use in ice cabins, the DUFTDOS-AK1 is equipped with a heater for the inlet nozzle to keep the inlet
nozzle free of ice.
Heating modes of the cabin:
When heating with a surface heating system, the surface temperature should not exceed 60°C
When heating with a sauna heater, the room temperature should not exceed 50°C.

3.2.1 Control unit
The control unit consists of a housing with a lateral orifice as air supply for
the built-in compressor. The compressor blows air across the surface of a
container filled with fragrance concentrate.
The electronic components are installed in the housing.
The operating parameters are set at the control unit.
The DUFTDOS type AK1 can be used to blow one fragrance into the cabin.
The device is equipped with a small compressor.
With the DUFTDOS type AK2 you can choose between 2 different fra-
grances. The device is equipped with two small compressors.
3.2.2 Button plate (option)
The scenting can be started with the button plate.
The button plate is available as a 1x version (AK1) or 2x version (AK2) and
is supplied with the corresponding flush-mounted box.
For details about the flush-mounted box, see supplementary sheet “BB
DW 001-03 Installation flush-mounted box V2” in the appendix.
3.2.3 Fragrance container
The fragrance container contains a filter star and the fragrance concen-
trate. The filter star is used to evaporate the fragrance concentrate.
The small compressor blows the evaporating fragrance concentrate from
the fragrance container into the line to the inlet nozzle.
Attention! Pay attention to the maximum fill volume of 50 ml.
3.2.4 Inlet nozzle (standard)
The inlet nozzle is used for the inflow and distribution of the fragrance flow
in the cabin.

3.2.5 Inlet nozzle with heater (option)
The inlet nozzle is used for the inflow and distribution of the fragrance flow
in the cabin. For ice cabins, the inlet nozzle is cast into a washer together
with a heater. The heating is necessary to prevent the nozzle from freezing.
The heating of the nozzle starts when the device is switched on and takes
place fully automated via the control unit. The heater is monitored. If a
fault occurs, the system switches off and the fault is shown on the display.
