Sample Gas Cooler Applications and Functions
Sample Gas Cooler
Applications
The SCC-C sample gas cooler forms part of the sample gas conditioning system
in an analysis system.
The moist sample gas is cooled in the sample gas cooler to such a degree that
the temperature does not fall below the dew point at any point further on in the
system, and thus no condensate can penetrate the analyzer.
Sample Gas Cooler
Functions
The functions of the SCC-C sample gas cooler are:
• Cooling the sample gas,
• Separating off the condensate and
• Removing the condensate.
With some specific measuring tasks the dew point of the sample gas must be
kept constant in order to nullify the influence of the water vapor on the
measurement result. In these cases, turning on the test gas before the sample gas
cooler has the effect of keeping the water vapor percentage in calibration
constant.
Use in conjunction
with the SCC-F
Sample Gas Feed
Unit
The SCC-C sample gas cooler can be used in conjunction with the SCC-F sample
gas feed unit.
The functions of the SCC-F sample gas feed unit are:
• Monitoring condensation,
• Feeding the sample gas, and
• Setting and monitoring the flow rate.
The functionality and operation of the SCC-F sample gas feed unit are described
in the operating manual (document no. 42/23-51 EN).
Note on
Explosion Protection
The SCC-C sample gas cooler must not be used in hazardous areas.
The model of sample gas cooler featuring stainless-steel heat exchangers is
suitable for use with flammable sample gases.
