3 SAFETY INSTRUCTIONS
Please take care of the following basic safety procedures when mounting, starting up or
operating this equipment:
Read this operating manual before starting up and use of the equipment. The information and
warnings given in this operating manual must be heeded.
Any work on electrical equipment is only to be carried out by trained specialists as per the regulations
currently in force.
Attention must be paid to the requirements of VDE 0100 (IEC 364) when setting high-power electrical
units with nominal voltages of up to 1000 V, together with the associated standards and stipulations.
Check the details on the type plate to ensure that the equipment is connected to the correct mains
voltage.
Protection against touching dangerously high electrical voltages:
Before opening the equipment, it must be switched off and hold no voltages. This also applies to any
external control circuits that are connected.
The device is only to be used within the permitted range of temperatures and pressures.
Check that the location is weather-protected. It should not be subject to either direct rain or moisture.
The equipment must not be used in hazardous areas.
Installation, maintenance, monitoring and any repairs may only be done by authorized personnel with
respect to the relevant stipulations.
4 WARRANTY
If the equipment fails, please contact M&C directly or else go through your M&C authorised dealer.
We offer a one year warranty as of the day of delivery as per our normal terms and conditions of sale,
and assuming technically correct operation of the unit. Consumables are hereby excluded. The terms
of the warranty cover repair at the factory at no cost or the replacement at no cost of the equipment
free ex user location. Reshipments must be send in a sufficient and proper protective packaging.

For protection against liquid breakthrough and to increase the dependability
of the complete system we recommend the use of a fluid alarm sensor.

6 APPLICATION
The Peltier Gas Sample Cooler Type ECP20 is used in analyser sample system design to reduce the
dew point of wet gases to a level that is stable and low.
Sample gas cooling prevents subsequent condensation in the analyser. The stability of the dew point
is also extremely important at it helps to prevent water vapour cross sensitivity and volumetric error,
especially in infrared analysers.
The sample gas passes through a sampling probe to the Type ECP20 Cooler where it is lowered to a
dew point of +5°C. Solids will have been trapped in the filter of the sample probe, (If provided in the
type used) or are trapped in a downstream fine filter.
The conditioned gas can now be passed to the analyser.
If the analyser has no gas flow control or indicator functions, these should be provided externally, just
as with a gas delivery pump for unpressurized gases.
The condensate is discharged externally:
For operations under pressure, an automatic condensate drain or collection vessel is used.
For operations in partial vacuum (suction), a condensate vessel with a manual drain or a peristaltic
pump for automatic condensate removal is used.
For protection against liquid breakthrough and to increase the dependability of the complete system
we recommend the use of a fluid alarm sensor.
The Type ECP 20... Peltier Gas Coolers are designed for use in gas analysis whenever moisture is
likely to effect results.

7 FUNCTION OF THE M&C JET-STREAM HEAT EXCHANGER
The ECP20-1 is equipped with one Jet-Stream heat exchanger for a flow rate of 250l/h while the
ECP20-2 has two heat exchangers in series for maximum flow of 500l/h.
The Jet-Stream heat exchangers made of Duran glass, optional 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 2 shows a schematic diagram of the functioning of
the heat exchanger.
