Gas sampling and gas conditioning technology 3-3.1-ME
6 INTRODUCTION
The patented M&C EC-L 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.
6.1 SERIAL NUMBER
The type plate with the serial number is located at the side panel of the cooler housing. Whenever you
call M&C regarding questions or orders for the spares please give us the serial number of your EC-L.

APPLICATION
Figure 1 shows a typical example of an application for installation of an EC-L gas cooler unit.

The gas to be measured is taken from the EC-L gas cooler

by a gas sample probe

via a heated
sample line

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. If required an aerosol filter

can be installed
downstream the flow meter
