3. Gas Cooler (option)
Exhaust gas with a temperature over the steam dew point (35 - 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 (semi-conductor cooling element)
flown by a continuous current is thermal 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 con-
veys 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 by a periodically working
hose pump.
By accumulator operation, the Peltier cooler can be switched off.
In the measurement menu press hereto <Enter>, select the menu
point „Peltier I/0“ and press again <Enter> (for Peltier cooler switch
on, just repeat this procedure).

The power needs of the gas cooler being high,
