1.7 Gas Cooler (option)
Hint
The ecom-EN3-F transport variant professional case is standard with a gas
cooler.

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 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 receptacle and is pumped out
on request by a periodically working hose pump.
Hint
When the gas cooler is active, the power requirement of the instrument
increases considerably. Therefore the cooling capacity of the gas cooler in the
battery operation is reduced.
Hint
The gas cooler can be deactivated in battery operation.
To deactivate the activated gas cooler, press the <Enter>
key when the measuring menu is active. Choose the menu
point "Peltier I / 0" and press the <Enter> key again.
To reactivate the deactivated gas cooler, repeat the
above steps.
