In case of battery operation the power is reduced
Exhaust gas with a temperature over the steam dew point (35 to
65 °C) is flown spiral via a long gas path thru a surface coated metal
body with good thermal conductivity. The gas radiates its heat to this
metal body. A PELTIER element (semiconductor cooling element)
flown by a continuous current is thermally connected with this body
and with a second metal body with cooling ribs and ventilation slots.
The flow thru the PELTIER element creates a heat transfer from
WARM to COLD, drains the heat of the metal body flown by gas and
conveys it to the outer cooling body. This heat is conveyed thru a
vertical forced ventilation to the surrounding air.
The condensation issued by the heat loss of the gas drops in a re-
ceptacle and is pumped out on request (either by the user or due to
the level monitoring) by a periodically working hose pump.
The sucking capacity of the gas conveying pump avoids a sufficient
dwell time of the gas with the condensate, so that wash out reactions

At the cooler outlet the gas has a temperature of ca. 5 °C with a rela-
tive saturation of nearly 100 % relative humidity (corresponds to a
water steam content < 7 g/m
