6INTRODUCTION
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 on the right side of the cooler housing (wall-mount). Please always
quote the serial number in case of queries and spare parts orders.

Analyzer
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 .
