86 INTRODUCTIONThe patented M&C EC30 gas cooler with universal unit EC-F and EC-30/FD with unit EC-FD is alwaysto be installed in situations where there is interference from moisture in the gas to be measured, or ifthe measured components exhibit very high sensitivity to water vapour or if long and expensive heatedsampling lines are to be avoided.Reduction of the gas temperature inside the cooler to a stable and very low dew point effects acondensing out of the sample gas. Dry gas leaves the gas cooler and passes into the analyser aftersuitable filtration. When installing the EC30(/FD) gas cooler on site in a frost-free protective housing,there is no need to use a heated sample line with a high energy consumption as long as the ambienttemperature does not fall below a value of -25 C.6.1 SERIAL NUMBERThe type plate with the serial number is located at the side panel of the cooler housing (19“ version).Whenever you call M&C regarding questions or orders for the spares please give us the serial numberof your EC30.Gas sampling and gas conditioning technology3-4.20-ME
97 APPLICATIONThe patented M&C ultra-low temperature cooler EC-30(/FD) finds its applications in the analytical fieldfor reducing the dew point of humid sample gases, providing a stable and very low dew point andreducing aerosol formation in the analyser. By mounting the cooler near to the sample point, costlyenergy consuming heated sample lines can be avoided. An extremely stable and low gas dew pointavoids water vapour cross-sensitivity and volumetric errors.Figure 1 shows a typical example of an application for installation of an EC-30 gas cooler unit.EC-301Sample gas INEC-Samplegas OUTCondensateOUTTest gasINFilter sample probe SP...

Via the universal unit EC-FD the condensate is removed. Thesuper-fine filter located afterwards removes solid particles. For increased operating safety of theentire system we recommend installing a super-fine filter with a liquid alarm sensor. If required anaerosol filter can be installed in front of the flow meter . The gas thus treated can now be passedinto the analyser . Via the 3-way-ball valve it is possible to feed test gas for calibration to theanalyser.Gas sampling and gas conditioning technology3-4.20-ME
