8 INTRODUCTION
The M&C EC-EX gas cooler unit is always to be installed in situations where there is interference from
moisture in the gas to be measured and if the point of installation is declared as hazardous area (see
appendix).
Reduction of the gas temperature inside the cooler to a stable and very low dew point effects a
condensing-out of the sample gas.
9 APPLICATION
Figure 1 shows a typical example of an application for installation of an EC-EX gas cooler unit.
Filter sample probe SP2000-H/Ex 3-way ball valve Super-fine filter FP...
Heated sample line Ex-version Peristaltic pump SR25.1/Ex Aerosol filter CLF
EC-EX cooler Membrane pump MP47/Ex Flow meter FM 10
Figure 1 Example of application of EC-EX
The gas to be measured is taken from the EC-EX gas cooler by a gas sample probe and cooled
down to a dew point of +5°C. 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 (for example LA1 with electronic controller type ER 142 Exi). 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 .

Figure 2 EC-EX cooler
The EC-EX is equally suitable for wall installation or mounting in a 19“ rack.
The versions differ in the positioning of the LED function display . While for wall installation the LED
function display can be fitted into the corresponding cut-outs in the EC-EX front panel, for 19” rack
mounting this is done using the cut-outs in the back panel of the casing. This positioning can be done
at the factory by when stating the type of installation of the EC-EX gas cooler. It is relatively simple to
subsequently reconfigure it on site at the user location. The location for installation of the LED function
display will be marked correspondingly.
The casing depth of the EC-EX cooler is 450mm. Additional installations within the casing aren’t
possible.
The electrical parts of the cooler EC-EX are explosion protected. The EC-EX control board and the
protective motor switch are mounted in a flameproof enclosure EEx-d .
