6 INTRODUCTION
The M&C cooler ECM is used for applications where interfering moisture loading in the sample gas is
to be expected.
By lowering to a very low stable dew point, condensation is prevented in the analyzer and a fluctuating
measurement value due to water vapour cross sensitivities or volumetric errors is avoided.
6.1 SERIAL NUMBER
The type plate with the serial number is located at the side panel of the cooler housing (wall mounting
version). Whenever you call M&C regarding questions or orders for the spares please give us the serial
number of your ECM.

The gas to be measured is taken from the ECM gas cooler  by a gas sample probe  via a heated
sample line  and cooled down to a dew point of +5 °C [41 °F]. 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 analyzer .
