APPLICATION
The Peltier Gas Sample Cooler Series TEC1 is a standalone device used in analyzer sample system designs
to reduce the dew point of wet gases to a level that is stable and low.
Sample gas cooling prevents subsequent condensation in the analyzer. The stability of the dew point is also
extremely important at it helps to prevent water vapor cross sensitivity and volumetric error, especially in
infrared analyzers.
The sample gas passes through a heated sampling probe and heated sample line to the Series TEC1 Cooler
where it is lowered to a dew point of +4°C (user adjustable). Solids will have been trapped in the filter of the
sample probe, (If provided in the type used) or are trapped in a downstream fine filter.
The conditioned gas can now be passed to the analyzer.
If the analyzer has no gas flow control or indicator functions, these should be provided externally, just as with a
gas delivery pump for unpressurized gases.
The condensate is discharged externally:
•
For operations under pressure, an automatic condensate drain or collection vessel is used.
•
For operations in partial vacuum (suction), a condensate vessel with a manual drain or a peristaltic
pump for automatic condensate removal is used.
For protection against liquid breakthrough and to increase the dependability of the complete
system, we recommend the use of a liquid alarm sensor.
The Series TEC1 Peltier Gas Coolers are designed for use in gas analysis whenever moisture is likely to either
affect results or damage analyzer equipment.
