Removing any moisture from the gas is an important step in sample gas
conditioning. To achieve this, suitable coolers are applied to reduce
the gas temperature below the dew point in order to condense the
moisture. To secure a reproducible analysis result the dew point must
remain as stable as possible even when the ambient temperature
fluctuates. The required cooling capacity depends on the temperature
fluctuations at the sampling site (which may vary over the course of the
year), the specific material combination for the heat exchanger to meet
the sample gas composition and the energy-efficient operation of the
cooler. Application specific different types of coolers and/or
precoolers may be required. The coolers are primarily electric gas
coolers, either semi-conductor or compressor coolers, the selection
determined by the requirements or the operating conditions. Replaceable
heat exchangers in a variety of material compositions and helpful
accessories and monitors complete the product portfolio, including for
EX zones.
