3. Gas Cooler (option) / Model version ecom-EN2-P
Exhaust gas with a temperature over the steam dew point (35 - 65 °C) is
flown spiral via a long gas path thru a surface coated metal body with
good thermal conductivity. The gas radiates its heat to this metal body.
A Peltier element (semi-conductor cooling element) flown by a continuous
current is thermically connected with this body and with a second metal
body with cooling ribs and ventilation slots.
The flow thru the Peltier element creates a heat transfer from WARM to
COLD, drains the heat of the metal body flown by gas and conveys it to
the outer cooling body. This heat is conveyed thru a vertical forced
ventilation to the surrounding air.
The condensation issued by the heat loss of the gas drops in a receptacle
and is pumped out on request by a pediodically working hose pump.
By accumulator operation, the Peltier cooler can be switched off.
In the measurement menu press hereto <Enter>, select the menu point
„Peltier I/0“ and press again <Enter> (for Peltier cooler switch on, just
repeat this procedure).
The power needs of the gas cooler being high,
the cooling performance shall be reduced
by accumulator operation!

ecom-EN2 Page 7
4. Power Supply
The ecom-EN2 comes with an external charger. The analyser can
also be powered via the internal accumulator for a while (6 V; 3.8 Ah).
The accumulator recharge should be started when the instrument
requires to (acoustical warning and display indication). The
accumulator charging stand can be checked looking at the voltage
indication on the display (menu "Control" - Info key). The accu warning
is activated when the value „Accu“ is smaller than 5.7 V.
By 5.4 V the power operation via accu is no more possible; the instrument
must be further powered via the external charger.
5. Data Memory
The multi-media card enables the storage of punctual measurements;
the gathered values are written in a text file (J2KDV.txt). Data format
information is to be found in the appendix. The files can be transferred
to a PC via a card reader.
The following conditions must be fulfilled for using a multi-media card:
- minimal card volume 32 MB - max. 2 GB
- card formatted on 16 bit FAT
- SD or MM card from rbr
- PC with card reader from rbr
- or from the manufacturers Belkin and SanDisk
Used accumulators can either be returned
to us or brought to recycling stations of
public waste disposal companies
respectively to stores selling accumulators!

The position of the measured and calculated values (gas analysis
sub-menu) on the display pages is free selectable. For alteration of
the existing succession, proceed as follows:
- Press <Enter> / „Display values“ / <Enter> to activate the function
- select line with cursor keys (Up/Down)
- select desired parameter with cursor keys (Right/Left)
- repeat procedure until desired layout is completed
- Press <Enter> to deactivate the function
Connect the sampling tubing on the instrument to the plug „Connection
gas“. Position the sampling probe in the exhaust channel, so that the
thermocouple is fully surrounded with the gas (see drawing).
Perform the measurement in the core stream of the exhaust gas
channel (probe placed in the hottest gas temperature area). A trend
indication for T.Gas easies the core stream search. As long as the display
shows an arrow in upwards direction, the measured temperature
increases, it means the probe tip moves towards the core stream
center. If an arrow in downwards direction is displayed, it means you
move the probe away from the core stream and the temperature sinks.
If no temperature change is shown for at least 3 seconds, so the trend
indication will disappear.

CO2, efficiency, losses, excess air and dew point are calculated values.
They can only be calculated if realistic values for the basic parameters
like O2and the temperatures are available. It must be ascertained
that:
O2< 20,5 % and T.Gas - T.Air > + 5 °C
are given. The dew point can only be calculated accurately if, in the
menu "Adjustments", the current barometric air pressure value has
been inputed. If the gas temperature falls below the dew point (between
25 and 65 °C), so efficiency will be calculated with condensation gain.
In this case a (K) is displayed after „Efficiency“.
Correct measurement values are displayed first after a short delay,
necessary for the gas transport and the build-up of a stable
electrochemical reaction to the sensors. This time period lasts approx.
1 to 1.5 minute. For recording, printout and evaluation, wait until the
values do not change anymore. If deviations higher than 2 ppm still
occur by the gas values, they can be due to unstable pressure conditions
in the exhaust channel.
If the measurement values are stable and
the results can be printed out, press the
key <Record> (disk symbol) to transfer
the values in the intermediate memory
(caution: store separately gas analysis,
CO, O2check and draught measu-
rements). They will be kept there for a
later printout and, if need be, for a final
data record storage.
If a printout of the values should be made simultaneously to the
intermediate recording, so press <F2> (the complete content of the
intermediate memory will be printed).

The CO sensor is protected against exceedings thanks to an internal
programme. If the 4000 ppm limit value is exceeded, so a purging
pump is activated which provides the sensor with fresh air. After sufficient
purging time (X behinds CO disappears) the sensor can be reintegrated
into the measurement system with <F3> (if you choose „Yes“ at
„Adjustments“ / „Internal“ / „CO-Automatic“ the CO sensor switchs
to measurement automaticaly). The sensor can also be manually be
excluded from the measurement system with <F3>.
8.2. CO Measurement (gas path check)
The gas channel check, called also CO measurement, is used for the
technical check of gas-fired plants in regards of safety aspects.
Hereby the CO concentration in the gas channel is measured after
the flow safety device and calculated on an undiluted value (oxygen
rest content in flue gas = 0%). As the gas conditions after the flow
safety device are no more homogeneous because of the flow in of
secundary air and consequently the core stream measurement can be
erratic, the analysis of the exhaust gas is performed along the totality of
the exhaust pipe diameter. A multi-hole probe (optional accessory) is
hereby used as sampling probe.
The calculated value shown on the line „CO
0 %“ corresponds to the measured CO
concentration supposed the oxygen
content would amount 0% by the same
exhaust gas volume. It is consequently
the undiluted CO content in exhaust gas.
If the values indication is stable, press
<Record> to store the result in the
intermediate memory. If a printout of the
values should occur simulataneously to the
recording in the intermediate memory
press <F2> (the complete content of the
intermediate memory will be printed out).

8.3. O2check
This measurement is performed by room-independant plants like gross
calorific value plants. It is determined if exhaust gas flows into the
combustion air (O2content drops down / CO content can be present)
and herewith influence on the combustion quality.
For this analysis, a special multi-hole pro-
be (optional accessory) should be used.
If the value indicated is stable, press
<Record> to store the value in the
intermediate memory. If a printout of the
values should occur simultaneously to the
recording in the intermediate memory,
press <F2> (the complete content of the
intermediate memory will be printed out).
8.4. Draught Measurement
A trend indication for the draught conditions in the exhaust channel
can already be viewed during the gas analysis. Nevertheless the value
for the chimney draught will not be stored together with the gas values
while pressing <Record> because the differential pressure sensor tends
to drifts because of its sensibility.
For an exact measurement, it is consequently advised to re-calibrate
this sensor just before sampling and documenting the value.
The display shows the current value as
well as the recommendation to re-set the
zero point of the sensor. Disconnect the
draught hose from the instrument for a
short moment and press <F4>. The sensor
is herewith re-calibrated.

previous stored in the intermediate
memory. The stored value is shown on
the display. Press <ESC> to exit the
draught measurement menu.
8.5. Flow measurement (option)
This measurement can be done with a pitot
tube. At first the pitot factor of the pitot tube
must be entered („Adjustments“ /
„Internal“ / „Pitot factor“). After
connecting the pitot tube to the
instrumentment, the zero point of the
sensor can be set with <F4>. With <F1>
the cross section of the flow channel can
be entered (needed for colculation of the
flow rate). After the pitot tube iss positioned
in the flow channel, the display shows the
speed (m/s) and the flow rate (Nm3/h). If
the value indicated is stable, press
<Record> to store the value in the
intermediate memory. If a printout of the
values should occur simultaneously to the
recording in the intermediate memory,
press <F2> (the complete content of the
intermediate memory will be printed out).
