Application

The patented M&C Ultra-Low Cooler EC-30
finds its applications in the analytical field
for reducing the dew point of humid sample
gases, providing a stable and very low dew
point and reducing aerosol formation in the
analyser. By mounting the cooler EC-30 near
to the sample point, costly energy consum­ing heated sample lines can be avoided.
An extremely stable and low gas dew point
avoids water vapour cross-sensitivity and vol­umetric errors.

Description

The patented M&C gas cooler EC-30 is a
two stage combination of compressor and
Peltier cooler with status alarm and automatic
defrosting of the dual deep freezer unit for
100% sample availability.

The pre-cooler “3“ of the gas cooler EC- is fit­ted with a “Jet-Stream“ heat exchanger EC-G
which is cooled by a compressor cooling
unit with electronic control at a constant
temperature of +2 °C. Optimum cooling of
sample gases and pre-elemination of a larger
part of the condensate from the gas is reliably
achieved.

No external pre-draining is normally needed.
The deep freezer “1“ and “2“ is cooled with two
modified “Jet-Stream“ heat exchangers EC-30
fitted between two automatic cooling units
for a minimum temperature of -30 °C.

The special design of the Jet-Stream heat
exchanger guarantees optimum dew point
reduction to a low, stable value and secures
condensate separation.

The gas outlets of the heat exchangers are
connected to a 3/2 way solenoid valve. An
electronic control system EC-30 switches
the solenoid valve for simultaneous change­over and automatic defrosting of the heat
exchangers EC-30.

In order to guarantee the necessary and
minimum operation of the gas cooler EC-30,
we provide this unit with an accessory mod­ule EC-F containing two fans for forced air
ventilation and cooling of the compressor
unit. Alternative we deliver an the cooler with
the module EC-FD containing additionally
three peristaltic pumps SR-25.1 for automatic
removal of condensate.
