Page 9 3. Peltier cooler j2kn pro must be plugged in for the peltier cooler to operate. Exhaust gas with a temperature above dew point is intro- duced into a spiralling gas path with a coated metal surface of good thermal conductivity. The hot gas radiates its heat to this metal coating, which is th...
