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.
