Sample Gas Cooler
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.
