Gas sampling and gas conditioning technology 3-4.1-ME
6 INTRODUCTION
The patented M&C EC/ECS gas cooler unit is always to be installed in situations where there is
interference from moisture in the gas to be measured.
Reduction of the gas temperature inside the cooler to a stable and very low dew point effects a
condensing-out of the sample gas.

Figure 1 Example of application of EC/ECS
The gas to be measured is extracted with a gas sample pump  via a gas sample probe  and a
heated sample line  and cooled down in the gas cooler EC/ECS  to a dew point of +5°C. The
emerging condensate is removed by a peristaltic pump or a collecting vessel . 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 . For calibration of the analyser a ball-valve  is existing.
