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 thermo­electric 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

Section C: Principle of Operation 5

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.

Figure 2: Heat Exchanger, Impinger and Heat Sink Assembly

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

°

(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.

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 D: Installation 7

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 E: Start-up Procedure 8

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 F: LED Indicators 9

Section H: Test & Adjustment Procedures 13

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 I: Description of Options 14

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).

MINI DIA-VAC®

MAINTENANCE AND DISASSEMBLY INSTRUCTIONS

A. General Operations Characteristics

1. Normal motor coil temperatures may be 160 - 180 degrees F. Winding insulation is Class B.
Please note the two fans are different, so before removing the fans, note which side they belong on.

2. To check pumping efficiency, employ suitably damped gauges connected so as to dead-end either
pressure or vacuum.
NOTE: Check each separately, One or the other port must be open during this test.
Use 0-60 PSI pressure gauge and 0-30 inch hg. vacuum gauge, (or mercury manometer).
Maximum pressure should be at least 33 PSIG for the .160 eccentric.
Maximum vacuum should be 21 inches Hg when using the .160 eccentric.

3. Match electrical power to motor

4. Do not start pump and motor with load of pressure or vacuum on pump head.

5. Pumps are intended for gaseous operation, eliminate liquids entering pump.

6. Nominal running amps for Mini Dia-Vac® at 115/230 volts are 1.7/0.8

B. Maintenance Procedures

1. Motor oiling - No oiling or other lubrication addition is necessary at all. All bearings are pre­lubricated and shielded from external contamination.

2. Diaphragm Replacement (also see Maintenance Procedure Below):

a. Standard EPDM (part 4302 or kit 11309) - Operating life can be five years or more under
conditions of light pressure or vacuum loads and infrequent operation. Over 20 PSI and constant
operation may require 3 month diaphragm inspection procedure. High ambient conditions over 100
degrees F may also decrease diaphragm life.

b. Teflon coated EPDM (part 4301 or kit 11305) - Satisfactory operation can be attained for periods
of 12 months or more under conditions of light pressure of vacuum loads.

c. Viton/Nomex (part 4303 or kit 11307) - same as b above.

Where critical processes may involve the pumping of corrosive or toxic gas media, it is
recommended that a monthly check of the diaphragm be part of a scheduled maintenance procedure.

Air Dimensions Inc. will supply recommendations on the choice of diaphragm material and or pump
head construction on request.

*Diaphragms require close precision tolerance, therefore only ADI diaphragms should be used as
replacements.

C. Disassembly of Head Section and Service Diaphragm

1. Remove head section by unscrewing the four large bolts. A flat-bladed screw driver may be
needed to gently pry the head free of the service diaphragm. **If you have Teflon coating on the
heads use caution not to scratch the surface.

2. The valve body can then be removed by unscrewing the two smaller screws (also accessible on
the top of the head section). This part may be freed by gently tapping on these two screws after they
have been loosened about three or four turns. When the valve body is removed, check all internal
surfaces for any accumulation of dirt. The two valve discs can be wiped clean and replaced as long
as they appear unaffected by usage. The valve gasket can be easily removed and should be
inspected. As a matter of good practice, the valve discs and valve gasket should be replaced during
any routine maintenance check of the head section. A once a year routine procedure is
recommended.

3. The service diaphragm is secured by the single screw in its center. Remove this screw with a
5/32" Allen wrench. The diaphragm and its clamping plate should be easily lifted off. Some slight
adherence to the metal may occur if the diaphragm has been in use for a long period.

4. When replacing the service diaphragm, a Teflon washer (part# 23001) should be inserted under
the head of the diaphragm cap screw. This is added insurance against small gas leaks through screw
heads and may be essential in vacuum applications where outside air contamination cannot be
tolerated. After tightening the screw, the excess Teflon should be trimmed away.

NOTE: When replacing the service diaphragm, be sure the four projecting studs of the base casting
are properly located in the four outer holes provided in the diaphragm before the part is clamped in
place. Be sure the diaphragm plate is firmly replaced with its center screw.

D. Disassembly and Replacement of the Connecting Rod

1. Remove head section and service diaphragm as described in (C) above. When this is done and the
front screen has been removed, the connecting rod assembly may be taken out (refer to exploded
view drawing). Gently pry up and remove the connecting rod cap (part# 3301) which is held in place
by the diaphragm screw.

2. Loosen but do not remove the counterweight screw. This is accessible from the top of the pump
base casting and will require a 5/32" hex allen wrench. The connecting rod eccentric assembly,
including counterweight and fan, will then slide of the motor shaft.

3. When replacing the eccentric assembly, be careful to align the flat section on the motor shaft with
the counterweight screw. The eccentric assembly should be aligned so the fan is on the outer side
from the motor. Slide this assembly as far onto the motor shaft as it will go before tightening the
counterweight screw onto the flat of the motor.

NOTE: After prolonged use, the eccentric assembly may freeze up on the motor shaft. A wheel
puller may be needed to free the part. When replacing the eccentric assembly, the motor shaft should
be lightly coated with a graphite or MDS based lubricant.

E. Related Torque Values

1. Head bolts - 110 inch pounds.

2. Valve body screws and Diaphragm plate screws - 70 inch pounds
