Section C: Principle of Operation 5
C: PRINCIPLE OF OPERATION
Thank you for purchasing a Baldwin Model 225 Thermo-Electric Cooler. Baldwin’s
Thermo-Electric Coolers are specifically designed for high ambient temperature &
high water volume applications. Each model features an oversized heat sink and
high performance thermoelectric devices for high heat removal capacity. Heat sinks
used in Baldwin Thermo-Electric Coolers are made out of high heat transfer
extruded aluminum with large 3/4" thick end plates. Each model also incorporates a
special controller specifically designed to run at high ambient temperatures.
The process of sampling combustion product stack gas or exhaust from internal
combustion engines requires a method to remove the moisture from the sample,
without removing the gas components of interest. The Baldwin Thermo-Electric
Cooler is an ideal way to decrease the dew point of combustion gases to a
repeatable, stable, constant low dewpoint. The Baldwin cooler prevents water
condensation in sample pre-filters, sample pumps, and gas analyzers. For gas
analyzers where water vapor is an interferant, a stable, repeatable dewpoint
becomes a part of the gas analyzer performance specification. Baldwin coolers
provide this constant low water concentration, resulting in an accurate component
gas measurement.
All Baldwin coolers use thermo-electric elements (Peltiers) to cool the sample gas to
the desired dew point temperature. A thermo-electric cooler is best illustrated as a
small heat pump with no
moving parts. The Peltiers
operate on direct current and
may be used for heating or
cooling by reversing the
direction of current flow. This is
achieved by moving heat from
one side of the module to the
other with current flow and the
laws of thermodynamics. A
typical single stage Peltier
(Figure 1) consists of two
ceramic plates with p- and n-
type semiconductor material
(bismuth telluride) between the
plates. The elements of
semiconductor material are
connected electrically in series and thermally in parallel.

When a positive DC voltage is applied to the n-type thermo-electric element,
electrons pass from the p- to the n-type thermo-electric element and the cold side
temperature will decrease as heat is absorbed. The heat absorption (cooling) is
proportional to the current and the number of thermo-electric couples. This heat is
transferred to the hot side of the Peltier element where it is dissipated into the heat
sink and surrounding environment.
Baldwin Thermo-Electric Coolers remove the moisture from the sample gas by
cooling the gas as it passes through a laminar impinger (heat exchanger). A
diagram showing the gas flow path through an impinger is shown in the Appendix.
The heat exchanger, made of 316L stainless steel, Durinert® (a corrosion-resistant
inert coating over 316L stainless steel), PVDF (Kynar), or glass, is mounted within a
thermally insulated heat transfer block bored to receive the heat exchanger without a
mechanical lock. This assembly allows the easy removal of any heat exchanger
simply by slipping it out of the cooling block by hand. The heat transfer block cools
the heat exchanger through the heat pumping action of the peltier element. The
heat transfer block is on the cold side of the thermo-electric element and the heat
sink is on the hot side of the thermo-electric element. The heat from the heat
transfer block is pumped to the heat sink where it is then dissipated into the air by
the heat sink fan. See Figure 2. The desired temperature is maintained by a closed
loop control system, which is implemented through an analog proportional controller.
The controller uses a type K thermocouple in the heat transfer block located very
close to the cold side of the peltier element as the input sensor.

Section C: Principle of Operation 7
The sample gas is passed to the thermo-electric cooler via the heated filter sample
probe and heated sample line. The thermo-electric cooler lowers the sample dew
point to 5°C (41°F). As the gas cools and the moisture vapor condenses, the
condensate exits the heat exchanger through the bottom drain connection.
Particulate matter which passes through the sample cooler is removed by an
optional Baldwin pre-filter, located downstream from the cooler along with an
optional water slip sensor. In the model 225, an add-on relay circuit board must be
purchased in order to use the optional water slip sensor. The conditioned sample
gas can then be directed to the gas analyzers.

Section D: Installation 8
D: INSTALLATION
The Model 225 thermoelectric sample cooler should be installed away from heat
sources in a well ventilated area of an instrument rack or enclosure. REMEMBER,
the Model 225 can only control to 71°F DIFFERENTIAL from ambient temperature.
Thus, at an output temperature control of 41°F, the maximum ambient temperature is
104°F, above which cooling control is lost. When this differential is exceeded, the
controller will go full-on, with the cooling capacity floating in relation to the ambient
temperature above 104°F. No damage will occur to the cooler, however, the output
dew point will also float in relation to the ambient temperature. The more stable the
ambient temperature environment around the Model 225, the better the output dew
point stability.
Sample tubing connections to the Model 225 depend on the heat exchanger material
of construction. A cooler with stainless steel heat exchangers uses a stainless steel
inlet fitting on the Channel 1 heat exchanger. All other inlets and outlets are Kynar®
standard compression type tube fittings with Teflon®ferrules. PVDF (Kynar®) heat
exchangers use all Kynar®standard compression type tube fittings with Teflon®
ferrules. Baldwin cannot warrantee against damage to the Peltier elements or heat
exchangers if our supplied Kynar®tube fittings are not used.
The inlet and outlet tubing of all metal or Kynar®heat exchangers is 1/4" NPT; the
user should always use the compression type fittings provided for that purpose by
the factory. The inlet of the Channel 1 heat exchanger uses a 3/8” tube x ¼” MNPT,
tube connector fitting to accommodate most standard 3/8” sample lines.
The condensate drain connections are Kynar®elbows, 3/8” MNPT x 1/4” barbed
tube fittings. An automatic condensate drain, Baldwin Model 3KPB-003 dual-head
peristaltic drain pump is recommended for water removal. This pump uses size 17
tubing.
CAUTION: Do no reduce the size of the condensate tubing since doing so restricts
water flow resulting in water slip (moisture carryover) in the sample.
CAUTION: If using a stainless steel sample line, place 2 inches of Teflon®tubing in
between the exchanger inlet fitting and the heated line. This prevents the sample
cooler from heat sinking the incoming heated line, which adds undue load to the
cooler.
.

Section E: Start-up Procedure 9
E: START-UP PROCEDURE
When connecting power to the 225 cooler, proper EARTH GROUNDING is
essential. Use a 15 amp minimum, three-conductor power cord. Connect the green
with yellow stripe conductor (Earthing) to the protective earthing ground lug on the
225 chassis. Using a small screw driver, install the brown conductor (Phase) in the
right terminal of the two-terminal connecter at the bottom left of the control board.
Install the blue conductor (Neutral) in the left terminal of the same terminal
connector.
Plug in the power cord to a properly grounded main circuit. The Ready Green LED
will come on within 3 minutes, indicating the relay temperature (10°C) has been
achieved and gas sample flow can begin. After approximately 3 minutes, the
setpoint of +5°C. (41°F.) is achieved.
The Baldwin Model 225 Thermo-Electric Cooler is virtually maintenance free.
However, in the event of electrical problems, refer to the troubleshooting guide in
this manual. All voltages can be read at the PCB terminal strip. Any deviations from
the correct voltages indicate a problem.

Section F: LED Summary 10
F: LED SUMMARY
The Model 225 has dual-channel front panel indicators with three LED status
displays for each active channel (2 green, 1 red per channel). These indicators are
arranged horizontally on the front of the cooler on their respective channel sides.
READY (green) LED On = Ready point temperature is reached 10°C (50°F)
OPERATING (green) LED On = Peltiers are active
TC FAILURE (red) LED On = Thermocouple or electronic failure alarm
The combination of the READY and OPERATING green LED's indicate the sample
cooler is operating in a safe, dry condition. Upon immediate power on, the
OPERATING green LED’s will light, indicating that the peltiers are active. The
READY green LED’s will not light until the heat exchanger temperature has fallen
below 10°C.
When all Green LED's are lit, the Model 225 is operating properly in normal, dry
condition, and the effluent sample gas is being dried to the operating set point of
5°C, producing a stable, repeatable dewpoint. If either Green LED fails to light, it can
indicate various problems. The most obvious is overload. Check the incoming
sample gas temperature, moisture content, and flowrate through the heat
exchangers to be sure all conditions are within published specifications. Overload
requires more cooling power from the Model 225 than is available (max. is 112
Btu/Hr) (118 kJ/Hr). If all conditions are correct, then the problem may be an
electrical malfunction, which can be traced using the trouble shooting guidelines in
Section J of this manual.
The very design of the Model 225 is such that overload will not cause damage to the
unit. Sample gas of a higher dew point is the result of overload. The flow
performance curves in the Appendix of this manual illustrate the relationship of
sample inlet temperature, flow rate, and the resulting sample effluent dew point.
Overloading the cooler forces this dew point curve higher.
An optional Water Slip Alarm circuit board and water slip sensor are available to
provide a relay (SPDT) contact for remote alarm sensing. This contact closure can
be used to stop and start a sample pump, alarm annunciator, or computer
malfunction alarm input.

Section I: “New Jersey” Thermocouple Option 14
I: “NEW JERSEY” THERMOCOUPLE OPTION
Some air quality management districts (e.g., those in New Jersey and Southern
California) require temperature measurement of the gas stream at the outlet of the
last heat exchanger on the cooler. Baldwin offers a 1/32-inch diameter hypodermic-
style type K thermocouple that can be inserted into a special heat exchanger (i.e., it
has a small port for insertion of the thermocouple) so the actual sample dew point
temperature can be measured. This is sometimes referred to as the New Jersey
thermocouple outlet temperature option.
The Model 225 has two 5” heat exchangers which can be operated in series (single-
stream) or in parallel (dual-streams). When run in series, the second heat
exchanger will have a New Jersey thermocouple to sense the temperature inside the
heat exchanger (upgrade option: 4C-NJ/K-5). A quantity of two (2) 4C-NJ/K-5 are
required for each cooler when used for dual-streams. In the part number, the “NJ”
identifies the upgrade for a NJ type thermocouple. The “K” identifies the
thermocouple itself as a type “K” thermocouple. The “-5” is the height of the heat
exchangers.
In addition, Baldwin offers an optional temperature transmitter board for signal or
voltage temperature output. This board has one input and two outputs per channel.
The input is for the type K thermocouple. The first output is an analog voltage output
that can be configured for either 0-2.5vdc or 0-10vdc for a 0°C (32°F) to 25°C (77°F)
temperature range. The second output is a 4-20mA for the same temperature
range.
A single-channel NJ thermocouple transmitter board (3CCB-012) is used when the
Model 225 is operated in series. A dual-channel NJ thermocouple transmitter board
(3CCB-013) - one channel per gas stream - is used when the Model 225 is run in
parallel.
