Description and Principle of Operation
APPLICATION
The Universal Analyzers Model 1095E Acid Aerosol "Freezer Chiller" is a system on a 21" x 27" plate designed to
achieve an exit dew point of -25°C. It is designed to remove moisture to a level of 650 PPM. This reduces the chances
of low levels of acid formation therefore protecting downstream components as well as minimizing losses of measured
components.
The use of a heated lter and a heated sample line are required to be installed between the sample extraction location
and the input of the 1095E sample cooler. The temperature of the sample must be kept above the boiling point of water
and above the dew point of any chemical reactions that would skew the desired analytical results.
DESCRIPTION
The Universal Analyzers Model 1095E Acid Aerosol "Freezer Chiller" contains a combination of Kynar and Glass/Kynar
impinger type heat exchangers. These are mounted within heat transfer blocks, which are cooled by thermoelectric
elements utilizing the "Peltier Effect". The condensate is removed in multiple stages, one at the temperature of the
ambient air surrounding the Freezer Chiller by owing through the impinger referred to as the Passive Channel, then
by passing the sample into a heat exchanger cooled to 4°C by the thermoelectric elements referred to as the Active
Channel. The sample gas is then further cooled by special cascaded Peltier elements to negative 25°C freezer alternating
Impingers controlled by a PLC. The 4°C Active Channel is also referred to as Channel 1 and the two freezer Channels are
referred to as Channel 2 and Channel 3.
In standard operation Channel 1 will always hold at 4°C within a band 1°C. Channel 2 and Channel 3 cycle their operation.
The normal cycle operations (no alarms) are as follows:
Channel 2 Pre-Chill and Channel 3 Off - This cycle is the initial status upon startup. The switching valve selects Channel 2
and Channel 2 has power applied to the cooling elements until it has reached -10°C or the Pre-Chill time has elapsed.
Channel 2 Dwell and Channel 3 Off - This Cycle is the main cycle for the cooling elements on Channel 2 to chill and
for sample to run through Channel 2. It will need to be adjusted to be long enough for Channel 3 to properly defrost but
shorter than the time for ice to build up in the outlet of Channel 2, causing the owswitch to trigger a 'Frozen Column'
alarm.
Channel 2 Dwell and Channel 3 Pre-Chill - During this cycle Channel 2 Dwell Time completes, Channel 2 continues to
cool, and sample continues to run through Channel 2. Channel 3 is triggered to cool for up to 30 minutes. If Channel 3
reaches negative 10°C before 30 minutes has elapsed this cycle will complete and move to the following cycle.
Channel 2 Off and Channel 3 Dwell - This Cycle is the main cycle for the cooling elements on Channel 3 to chill and
for sample to run through Channel 3. It will need to be adjusted to be long enough for Channel 2 to properly defrost but
shorter than the time for ice to build up in the outlet of Channel 3, causing the owswitch to trigger a 'Frozen Column'
alarm.
Channel 2 Pre-Chill and Channel 3 Dwell - During this cycle Channel 3 Dwell Time completes, Channel 3 continues to
cool, and sample continues to run through Channel 3. Channel 2 is triggered to cool for up to 30 minutes. If Channel 2
reaches negative 10°C before 30 minutes has elapsed this cycle will complete and move to the following cycle.
A Moisture sensor is provided to sense the presence of condensate, should any exist in the tubing following the chiller.
This WCSF (Water Carry-Over Sensor with Filter) includes a visible steel ber lter. This WCSF allows the operator
to inspect the condition of the heated stack lter. The integral moisture sensor with the sensing elements is located in
the bottom of the lter bowl to provide an early warning if liquid carries over past the freezer chiller. If water carry-over
is sensed, the Alarm Message “Water Carry-Over” is displayed. With Channel 1 Chiller high temperature (>10°C) the
Operator Interface displays “Ch1 High Temp”. Either of these stops the Sample Pump.

Page 6 of 25 Page 7 of 25 MAN.1095E.REVB.12232014
A Vacuum switch is provided to monitor and alarm high inlet vacuum. The message “System Vacuum” will appear on the
top system status line of the operator interface, if there is high inlet vacuum.
A Flow switch alarms on low ow. The message “Low Sys Flow” will appear on the top system status line of the operator
interface, if there is low ow.
The heated head sample pump (oil-less diaphragm pump) is placed in the sample line between the 4°C and minus 30°C
heat exchangers. The rst chilled heat exchanger takes enough of the water vapor from the sample to protect the pump.
The freezer heat exchangers are under a slight pressure because they are on the discharge side of the pump. This will
cause the dew point of the sample to be at its minimum. The pump has a sample pressure controller that is set at 10 PSI.
A Teon Solenoid is used to alternate the online negative 25°C column and the ofine channel that is in defrost mode.
The active freezer column ow impedance is monitored by a Flow switch to sense column freeze-up. If a ow restriction
is sensed before Online Dwell time out, the Alarm Message “Column Frozen” is displayed and after a time delay of 60
seconds the PLC will sequence to the other Freezer Column.
The ofine column is pre-chilled to approximately negative 10°C before the column is brought online. Once the pre-chill
column is below negative 10°C, the program automatically advances to that column or after 30 minutes of pre-chill time
the pre-chill channel goes online. If the column fails to cool for 15 minutes once it is online, the message “Ch2 or Ch3
Malfunction” will be displayed.
The standard drain is a peristaltic pump is a positive displacement pump that allows for use in either a pressure or
vacuum sample. It provides for easy leak detection but does require periodic maintenance in replacement of the tubing.
A preventative maintenance program replacing the tubing every 6 months is a good practice.
To assist with the ow control a 5 Liter per minute owmeter with needle valve is provided. Many analyzers require
between 1/2 Liter and 1 Liter per minute. Any extra ow can be sent into a bypass to increase the total ow which in turn
increases the response time of the system.

Description and Principle of Operation
Installation
The sample inlet is a 3/8” compression tting supplied on the top of the rst Impinger. The heat insulation on the
heated tube bundle should be stripped no more than 3” to avoid plugging the exposed line. The sample outlets are 1/4"
compressions ttings on the owmeter.
A 3/8" tubing tting is provided as the condensate drain connection at the bottom of each heat exchanger. This can be
removed to expose 3/8" NPT female connections. Two dual-head peristaltic pumps are used to withdraw the condensate
from each Impinger. Care must be taken to drain the condensate into a safe drain because of the presence of condensed
sulfuric acid.
The electrical power, maximum 7.83A at 115VAC or 3.92A at 230VAC should be supplied. Installation shall be in accord
with the manufacturer's instructions and the national electric code (ANSI/NFPA70). Tampering and replacement with
non-factory components may adversely affect the safe use of the system. Customer input power connections are on TB6.
Customer 24VDC input signals to manually hold a column indenitely are on TB5-1 and TB5-2. Customer 234VDC input
signals to manually activate the system ofine function are on TB5-3 and TB5-4. A 24VDC output signal to signify there is
a system error may be wired on TB5-5 and TB5-6.
SEQUENCE TIMES SCREEN
The Dwell Time Minutes button allows the user to adjust Freezer Channel sequence time
between 50 and 180 minutes.
The Pre-Chill Time Minutes button allows the user to adjust the Next Up Channel pre-chill
time between 20 and 40 minutes.

NOTE: IT IS IMPORTANT THAT THE HEATED PROBE AND HEATED SAMPLE LINE SHOULD BE
AT OPERATING TEMPERATURE BEFORE STARTING THE CHILLER AND SAMPLE PUMP.
Apply power to the sample cooler. Channel 1 temperature should start to drop immediately. It will be below the over-
temperature set points, (10°C), in approximately four minutes and the sample pump should start as the program leaves
the start-up mode and enters run mode. Channel 1 will operate at approximately 4°C.
For Touch-Screen User Interface See Page 8.
Shutdown
Before removing power from the unit, ensure the system has been purged of any potentially hazardous components.
To purge the system, perform the following:
1. Perform a manual blowback operation.
2. If feasible, provide instrument air to the probe via a cal gas line. If not, disconnect the sample line.
3. Allow the system to run for at least 10 minutes.
4. Once purging is complete disconnect and cap the sample outlet tube connections and disconnect power from the unit.
Note: If electrical wires are to be disconnected, follow applicable ‘Lock Out/Tag Out’ requirements.

INSTALLING OR REPLACING HEAT EXCHANGERS
REMOVING THE HEAT EXCHANGER
1. Remove the inlet and outlet tubes by loosening the compression ttings. Always use a backup wrench on the tting
body to ensure no damage to the heat exchanger occurs.
2. Remove the drain tting using the same procedure as the inlet/outlet. Remove the drain ttings from the exchanger.
Use a backup wrench on the lower heat exchanger hex to prevent damage to the exchanger.
REPLACING THE HEAT EXCHANGER
1. Dry and clean the heat exchanger opening in the heat transfer block using a dry, lint-free cloth (If reusing the heat
exchanger, clean the outside as well.) Dried heat transfer paste can be removed by using a very ne abrasive pad
wrapped around a drill bit
2. Apply a thin layer of heat transfer paste onto the outer diameter of the heat exchanger.
3. Gently push the heat exchanger into the heat transfer block until the head is fully seated against the insulation on top.
4. Reinstall the drain tting. Ensure pipe tape is used on the pipe threads before installation. Use a backup wrench on

INSPECT/ CLEAN HEAT SINK FINS
INSPECT HEAT SINK FINS
Using a ash light (or other light source), shine a light through the heat sink ns. If the ns are unobstructed, you should
be able to see the exhaust fan. If the fan is not visible or partial obstruction exists, clean the heat sink ns.
CLEAN HEAT SINK FINS
Using a soft bristled brush, gently remove to debris from the heat sink. Alternatively, a computer safe aerosol cleaner
can be used to remove the debris. Clean any loose debris from the enclosure and blower motor using a vacuum or
compressed air.

THE PRESENCE OF WATER IN LIQUID FORM AFTER THE SAMPLE COOLER IS AN INDICATION OF A
FAULT IN THE SYSTEM. REASONS FOR THE PRESENCE OF CONDENSATE IN THE SYSTEM AFTER
THE SAMPLE COOLER COULD BE ONE OR MORE OF THE FOLLOWING:
1. Overloading of the cooling capacity of the cooler due to too much water vapor in the sample OR too great a sample
ow rate.
2. The condensate removal equipment (peristaltic pump, eductor, or drain pot) may be faulty. The heat exchanger(s)
may be full of condensate.
3. An air leak may be in the condensate removal system allowing air to enter and blow the condensate back into the heat
exchanger. (This assumes the heat exchanger is under a slight vacuum.)
4. The temperature of the air passing through the cooler to cool the heat sink is too high. This could be due to placement
of the cooler in a tightly sealed box.
