Gas sampling and gas conditioning technology 3-4.1ME EC-EX 9904
12 FUNCTION
The M&C EC-EX gas cooler is a compressor cooler with status alarm capability. This ensures 100%
availability of the cooler.
Up to 4 Jet-stream heat exchangers made of Borosilicate glass, PVDF or stainless steel are located in
a heat-insulated cooling block. All the heat exchangers are easily accessible and are arranged in such
a way that they can be removed very simply.
Figure 3 shows a schematic diagram of the functioning of the heat exchanger..

Figure 3 Functioning of heat exchanger
The compressor cooler system has a heat-insulated cooling block at a constant temperature of +5°C.
The novel construction of the heat exchanger guarantees a very good pre-separation of condensate
and for that reason an optimal drying of sample gas.
Alarm warnings for over- and under-temperature are given as a collective status alarm via a relay
output with two potential-free changeover contacts. Alarm will be released if the current temperature is
out of a range of

3°C referring to the set-temperature (+5°C).
