Gas sampling and gas conditioning technology 3-4.20-ME
7 APPLICATION
The patented M&C ultra-low temperature cooler EC-30(/FD) finds its applications in the analytical field
for reducing the dew point of humid sample gases, providing a stable and very low dew point and
reducing aerosol formation in the analyser. By mounting the cooler near to the sample point, costly
energy consuming heated sample lines can be avoided. An extremely stable and low gas dew point
avoids 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.

Figure 1 Example of application of EC-30/FD
The gas to be measured is taken from the EC-30/FD gas cooler  by a gas sample probe  and
cooled down to a dew point of -30°C. Via the universal unit EC-FD  the condensate is removed. The
super-fine filter  located afterwards removes solid particles. For increased operating safety of the
entire system we recommend installing a super-fine filter  with a liquid alarm sensor. If required an
aerosol filter  can be installed in front of the flow meter . The gas thus treated can now be passed
into the analyser . Via the 3-way-ball valve  it is possible to feed test gas for calibration to the
analyser.
