Application

The M&C gas cooler ECM is used in gas
analysis to lower the dew point of humid
gas to avoid condensation in the analyser(s).
An extremely stable and low gas dew point
avoids water vapour cross-sensitivity and vol­umetric errors.

Description

Compact, maintenance-free and self-control­ling. Intelligent detailed solutions provide
optimum cooling of the sample gas and
direct separation of condensate to avoid con­tamination effects.

The new controlled compressor cooling sys­tem and the special design of the jet stream
heat exchanger guarantee an optimum dew
point reduction to a low, stable value. An
additional pre-drainage device is not neces­sary in normal applications.

The condensate should be removed with
integrated small peristaltic pumps SR25.2 or
optionally by external condensate traps AD...
respectively collection vessels TG../TK..

The simple construction enables heat
exchangers of different materials to be used
depending on the application. Heat exchang­ers to be ordered optionally.

The digital indicator in the front panel dis­plays the cooling temperature. The function
of the cooler can be externally controlled via
the alarm contact, configurated at <+2 °C and
>+8 °C as a standard.

The gas cooler ECM-1 (1-channel) can be
equipped with one Jet-Stream heat exchang­er with a flow capacity of max. 250 Nl/hr.

The gas cooler ECM-2 (2-channel) can be
equipped with two Jet-Stream heat exchang­ers with a flow capacity of max. 150 Nl/hr
each.

The explosion-proof versions ECM-EX2-1 and
ECM-EX2-2 can be used in Ex-zone 2 and, they
too, may additionally be equipped with up to
2 standard peristaltic pumps SR25.2.

The compact and light weight construction
allows a simple and space-saving installation.
The ECM gas coolers are self controlling and
maintenance free in operation.
