Peltier gas cooler
The integrated Peltier gas cooler is designed for applications at
changing sites requiring high-precision gas analyses and involving
pollution and condensate in the flue gas.
The analysis of strongly water-soluble gases (NO2 and SO2) makes
the use of a Peltier gas cooler indispensable. The reduced dew point
of the measured gas avoids the formation of condensate and dirt
particles in the analyser and in other system components. At the
same time, a stable output dew point prevents vapour cross sensitiv-
ity and volumetric errors.
The gas cooler operates with an electronically controlled Peltier ele-
ment which ensures, together with the flow-optimised heat ex-
changer, an optimum dew point reduction to a value of approx. 5°C.
The condensate is discharged via a hose pump.
The Peltier cooler indicates the operating states of the individual sys-
tem components by means of status indicators.
Application example
Fig. 2: Application example Peltier cooler
The gas to be measured is drawn in via a gas sampling probe and a
heated gas line and supplied to the Peltier cooler. The heating hose
is heated to a temperature of 100 °C by a controller in the Peltier gas
cooler.
The gas cooler cools down the gas to a dew point of 5 °C; the con-
densate is discharged via a hose pump. The downstream fine filter
removes solid particles that may be contained in the gas.
Design
The Peltier gas cooler comprises a gas cooler with automatic con-
densate discharge as well as an easily accessible gas filter. An
