The cooler ECM-ExII is equally suitable for wall installation. The depth of the housing of the cooler is
270mm (316mm with optional mounted peristaltic pumps ).
W A R N I N G !
The cooler ECM-ExII corresponds to the system protection IP20 (EN
60529) and therefore suitable for use in clean and dry rooms. Solids
and water must be avoided to enter the cooler housing via the
ventilation outlet. For installation according to NEC article 501.4 (B)
(2) (conduit installation) the cable glands have to be changed with
the enclosed Conduit Hub.
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 ECMExII 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 6-12mm; 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.
12 FUNCTION
The M&C gas cooler type ECM-ExII 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. 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.
