Section C: Principle of Operation 5
C: PRINCIPLE OF OPERATION
Thank you for purchasing a Perma Pure Baldwin™-Series Thermo-Electric Cooler. This
Modular Series features a unique slim design leaving additional space to install or access
other sample conditioning system components. A unique drop-down door on the Modular
Series provides easy access to electronic boards and the power supply. All electronic
boards (control, relay, and display) are mounted on the door for easy access.
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-Series 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-Series coolers
provide this constant low water concentration, resulting in an accurate component gas
measurement.
All Baldwin-Series 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
elements. This heat is transferred to the hot side of the Peltier element where it is
dissipated into the heat sink and surrounding environment.
Baldwin-Series 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.
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 5qC
(41°F). As the gas cools and the moisture vapor condenses, the condensate exits the heat
exchanger through the bottom drain connection. Particulate matter passing through the
sample cooler is removed by an optional Perma Pure pre-filter, located downstream from the
cooler along with an optional water slip sensor. The conditioned sample gas can then be
directed to the gas analyzers.

Section D: Installation 7
D: INSTALLATION
The Model M325 should be installed away from heat sources in a well ventilated
area of an instrument rack or enclosure. The more stable the ambient temperature
environment around the Model M325, the better the output dew point stability.
Sample tubing connections to the Model M325 depend on the heat exchanger
material of construction. A cooler with a stainless steel heat exchanger uses a
stainless steel inlet fitting. The outlet is Kynar®standard compression type tube
fitting with Teflon®ferrules. A PVDF (Kynar®) heat exchanger uses Kynar®standard
compression type tube fittings with Teflon®ferrules. Baldwin cannot warrantee
against damage to the Peltier element or heat exchanger if our supplied Kynar®tube
fittings are not used.
The inlet and outlet tubing for 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
fitting to mate with most standard 3/8” sample lines.
The condensate drain connection is a Kynar®elbow (or straight), 3/8” MNPT x 1/4”
barbed tube fitting. An automatic condensate drain, Baldwin Model 3KPB-003
Peristaltic Pump, dual head, 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 8
E: START-UP PROCEDURE
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. After approximately 3 minutes, the set point of +5°C. (41°F) is achieved.
The SLIP Green LED should also be on if a water slip sensor is connected to the
internal relay board. The sample gas flow may be started immediately after the
READY Green LED comes on.
The Model M325 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 Indicators 9
F: LED INDICATORS
The Model M325 has two green and one red LED operating indicators. These
indicators are arranged vertically on the front of the cooler. The bottom green LED
indicates the READY operating temperature status, normally set for 10°C (50°F).
After the set-point temperature is reached, the sample pump may be turned on by
other devices. When the impinger temperature is below 10°C (50°F) the ready LED
will be on. Above this temperature, the ready LED will be off. The middle green
LED (applicable when the alarm relay option is installed) is ON when there is NO
water carry over and OFF when there IS water carry over. The red LED at the top is
the thermocouple failure indicator. When this occurs, the red LED stays illuminated.
The M325 Modular cooler has an analog voltage output. This output is factory
standard at 0-2.5 VDC = 0-25°C. The connector for this output is located on the
bottom of the cooler. It is labeled “Analog Out” (TB1).

Section G: I/O Terminal Block Description 10
G: I/O TERMINAL BLOCK DESCRIPTION

Section H: Test & Adjustment Procedures 11
H: TEST &ADJUSTMENT PROCEDURES
NOTE: All test and adjustment procedures have been performed at the factory.
Therefore, no adjustment should be necessary.
A. Main Control board
(1) WARNING: Before connecting power to the cooler, be aware of the
HAZARDOUS LIVE VOLTAGE on the control board. Disconnect power from the
cooler before opening the swing-down "L-door". Note: The auxiliary output board
must be removed if the cooler is so equipped. Remove the thermocouples from TB1
and TB2. The thermocouple generator should not be connected to either of the
thermocouple inputs at this time. Connect power to the cooler. After 10 to 20
seconds, the red LED(s) (thermocouple failure indicators) should be on.
(2) Connect the thermocouple generator to the Channel 1 thermocouple input, (TB1
terminal), inserting the yellow wire into the terminal marked Y and the red wire into
the terminal marked R. Turn on the generator. The red LED should turn off.
Connect a voltmeter between the ground test point, TP7 and TP1, the red lead to
TP1 and the black lead to TP7. Set the thermocouple generator to 0°C. Set the
voltmeter to 20vdc range.
(3) Adjust POT1 (the zero pot) to obtain a 0vdc reading on the voltmeter.

(3) Adjust POT1 on the display board so the display corresponds to the voltmeter
reading. That is, if the voltmeter reads 0.5vdc, adjust the pot so that the display
reads 0.5.
C. Auxiliary Analog Output Board
(1) WARNING: Before connecting power to the cooler, be aware of the
HAZARDOUS LIVE VOLTAGE on the control board. Disconnect power from the
cooler before opening the swing-down "L-door". Remove the thermocouples from
TB5 and TB6 on the auxiliary analog output board. The thermocouple generator
should not be connected to either of the thermocouple inputs at this time. Connect
power to the cooler. After 10 to 20 seconds, the red LED(s) (thermocouple failure
indicator) on the auxiliary analog output board should be on.
(2) Connect the thermocouple generator to the Channel 1 thermocouple input (TB5
terminal), inserting the yellow wire into the terminal marked Y and the red wire into
the terminal marked R. Turn on the generator. The red LED (CR5) should turn off.
Set the thermocouple generator to 0°C.
For Voltage Output
(3) If the auxiliary analog output board is set for voltage output, set the voltmeter to
20vdc range. Connect the voltmeter to TB2 (the channel 1 voltage output terminal),
the black lead to the negative (-) terminal and the red lead to the positive (+)
terminal.
(4) Adjust POT4 (the zero pot) to obtain a 0vdc reading on the voltmeter.
(5) Set the thermocouple generator to 25°C.
(6) Adjust POT1 (the span pot) to obtain a full scale voltage reading on the
voltmeter. This value will depend on the gain that was specified for the cooler at the
time of manufacture. Available gains are 0-1.0vdc, 0-2.5vdc, 0-10.0vdc for a 0°C-
25°C temperature range.

Section H: Test & Adjustment Procedures 13
For Current Output
(3a) If the auxiliary analog output board is set up for current output, set the ammeter
to 200ma range. Connect the ammeter to TB1 (the channel 1 current output
terminal), the black lead to the negative (-) terminal and the red lead to the positive
(+) terminal.
(4a) Adjust POT4 (the zero pot) to obtain a 4mA reading on the ammeter.
(5a) Set the thermocouple generator to 25°C.
(6a) Adjust POT1 (the span pot) to obtain a 20mA reading on the ammeter.

Section I: Description of Options 14
I: DESCRIPTION OF OPTIONS
Baldwin Modular Series Thermo-Electric Coolers have three available options: (1)
temperature display; (2) alarm relay/water slip, and (3) auxiliary analog output.
Modular Series Coolers may be equipped with any one or all of the options. All
external I/O connections for these options are available through the terminal blocks
on the bottom of the cooler.
1. Display Option (standard on model M325)
The display option is a secondary board that is mounted on the main control board.
This board has a three-digit LCD display that displays the temperature (in degrees
C) of the active channel(s). If the cooler has two active channels, there will be a
toggle switch installed to select Channel 1 or 2.
2. Alarm Relay/Water Slip Option (standard on model M325)
The alarm relay/water slip option is a secondary board that is mounted on the main
control board. This board has two inputs and three outputs per channel. The first
input, which comes from the main control board, is the ready input. The second
input, which comes from the water slip sensor, is the water slip input. The first
output, which is fed back to the main control board, controls the ready and water slip
LED(s). The second output is a 1/4 amp SPST form A dry contact relay. This relay
is used for computer sensing and is NOT intended for the controlling of electrical
loads. The third output is a 6-amp DPST form C dry contact relay. This relay can be
used for sample pump or other heavier electrical load control. This relay output
terminal is normally wired for a 120vac sample pump (ground, neutral, and line). If
there is water carry over (water slip LED), computer sense and load control relays
will be turned off. If the temperature of the cooler rises above 10°C (50°F), the ready
LED, computer sense and load control relays will be turned off. This means that the
relays operate in a fail-safe manner.
Note: If the alarm relay/water slip option is not installed, the SLIP LED(s) on the
front of the cooler will be off.
3. Auxiliary Analog Output Option
The auxiliary analog output option is a secondary board that is mounted on the main
control board. This board has one input and two outputs per channel. The input is
for a K type thermocouple. The first output is an analog voltage output that can be
configured for either 0vdc to 2.5vdc or 0vdc to 10vdc for a 0°C (32°F) to 25°C (77°F)
temperature range. The second output is a 4-20 mA for the same temperature
range. The K type thermocouple is normally a 1/32-inch diameter hypodermic type
thermocouple that is installed in a special impinger so the actual sample dew point
temperature can be measured.
Note: This option is sometimes referred to as the New Jersey thermocouple outlet
temperature option.

Section J: “New Jersey” Thermocouple Option 15
J: “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. Perma Pure 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 second 5” heat exchanger on the M325 can be upgraded to include the New
Jersey thermocouple option. This heat exchanger will have a New Jersey
thermocouple to sense the temperature inside the heat exchanger (upgrade option:
4C-NJ/K-5). 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, Perma Pure 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. The M325 utilizes a single-channel NJ thermocouple transmitter board
(3CCB-012).
