The cooler ECM is equally suitable for wall installation. The depth of the housing of the cooler is 270
mm [10.63”] (316 mm [12.44”] with optional mounted peristaltic pumps).
On the upper side of the cooler casing you will see the cutouts for 1 or 2 heat exchangers. Sample gas
enters and leaves the heat exchangers by the correspondingly connections on the upper part of the heat
exchangers (see 8. technical data).
The main power connector and the contact output for the status alarm can be connected at terminals
X1 respectively X3 located behind the removable front panel of the ECM housing.
At the bottom of the housing the following connections are provided as standard:
• standard condensate outlets from the heat exchangers,
• cable bushings 2 x M20 x 1.5 clamp range 6-12 mm;
With under- respectively ambient pressure the condensate removal happens via the peristaltic pumps
SR25.2 optionally implemented in the cooler housing or externally with collecting vessels type
TG.../TK... . With over-pressure an automatic liquid drainer type AD-... is suitable.
10 FUNCTION
The M&C gas cooler type ECM is a compressor cooler with status alarm capability. This ensures 100%
availability of the cooler.
Up to 2 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: The compressor cooler
system has a heat-insulated cooling block at a constant temperature of +5 °C [41 °F]. 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.
