The Parker Balston HPN2-1100 and UHPN2-1100 Ultra High Purity (UHP) Nitrogen Genera-
tors (see Figure 1) are completely engineered systems which will convert compressed air into
UHP-grade nitrogen. The systems utilize a combination of purification technologies including
filtration, catalytic oxidation (UHPN2-1100 only), and pressure swing adsorption. The UHP Ni-
trogen Generators are designed to provide high purity nitrogen gas for analytical instrumenta-
tion and other laboratory applications.
The HP/UHP Nitrogen Generators are certified to the electrical requirements as specified by
the IEC, CSA, and UL standards. These units bear both the CSA and CUL markings on the
product label. Product supplied to EU carry the CE mark (220/230/240 VAC units only).
The Parker Balston HP/UHP Nitrogen Generators include all the components required to con-
vert compressed air into ultra high purity nitrogen. The flow schematics (see Figure 2) show
all of the major components of the system. The system can be broken down into four primary
stages: prefiltration, hydrocarbon removal (UHPN2-1100 only), oxygen, carbon dioxide, water
vapor removal, and final filtration.
A Balston high efficiency coalescing filter has been incorporated into the design of the Ni-
trogen Generator as a prefilter to remove oil, water, and particulate contamination from the
incoming compressed air supply. The inlet prefilter assembly is equipped with an automatic
float drain to eliminate any liquids which have accumulated within the filter housing.

Hydrocarbon Removal
(Model UHPN2-1100 only)
Oxygen Removal
Final Filtration
In addition to the coalescing prefilter, particulate filters are incorporated into the design of the
Nitrogen Generator to protect internal components from particulate contamination. The Model
UHPN2-1100 has two Grade BX Balston particulate filters, and the Model HPN2-1100 has one
Grade BX particulate filter as shown on the Flow Schematics (Figures 2 and 3).
The catalyst module used for hydrocarbon removal is a stainless steel vessel filled with catalyst
and assembled with a cartridge heater. This catalyst module oxidizes hydrocarbons in the
compressed air supply to water vapor and carbon dioxide, which are removed in subsequent
purification steps.
The next stage in the purification process of the Parker Balston Nitrogen Generator is the
removal of oxygen, water vapor, and carbon dioxide from the compressed air supply. In this
stage, pressure swing adsorption (PSA) technology is utilized to reduce the concentrations of
these compounds to <1 ppm (each).
The final filter on the Parker Balston Nitrogen Generator is a Balston Grade GS membrane
filter which removes particulate contamination to 0.01 micron (absolute).

There are three diagnostic indicator lights and two digital pressure gauges on the Parker
Balston Nitrogen Generator.
System Check LED (yellow) - The "System Check" LED indicator has two functions: to signal
system start-up mode or to signal low inlet pressure. If the yellow "System Check" LED is
blinking (once per 12 seconds), the generator is in its start-up mode. If the "System Check"
LED is solid, the inlet air pressure has dropped below 60 psig (4.1 barg). In the event of low
inlet pressure, the generator will also emit an audible beep to alert the operator of this condi-
tion.
System Ready LED (green) - The "System Ready" LED indicator will illuminate when the
generator has completed its warm-up phase and is ready to deliver UHP nitrogen to the down-
stream process or equipment.
Service System LED (yellow) - The "Service System" LED indicator also has two functions. If
the LED is blinking, it is time to replace the hydrocarbon catalyst module as part of the routine
maintenance of the generator. If the LED is solid, there may be a possible fault with the hydro-
carbon catalyst module heater (Model UHPN2-1100 only) or the electrical connections to it.
This indicator light is inoperative in the Model HPN2-1100 generator.
Inlet Pressure Display - The inlet pressure displays the pressure of the compressed air supply
coming to the generator.
Receiver Pressure Display - The Receiver Pressure displays the pressure swing within the
internal receiver tank. This diagnostic display allows the operator to monitor the operation of
the PSA tower and to determine if there is a possible leak or overflow condition (downstream)
which could adversely affect the quality of the nitrogen supply.
All installation, operation, and maintenance activities for the Parker Balston Nitrogen Gen-
erator should be performed by suitable personnel using reasonable care.
Diagnostics
The Parker Balston Nitrogen Generator is a free-standing unit. Do not suspend the Nitrogen
Generator from the wall or ceiling. Its considerable weight could pose a falling hazard to
personnel and equipment in its proximity. Do not install the unit outdoors. When moving
the generator, use proper equipment and lifting techniques. Do not grasp the front panel
when moving the generator. Lift the generator by the metal case only.

The inlet fitting for the Nitrogen Generator is 1/4" female NPT, and the outlet fitting is 1/8" female
NPT. A shut-off valve and pressure regulator should be installed directly upstream from the
Parker Balston®UHP Nitrogen Generator (see Figure 4). The shut-off valve isolates the unit from
the compressed air line for maintenance and troubleshooting activities. The pressure regula-
tor controls the inlet air pressure and should be set to deliver compressed air to the generator
between 60 psig and 125 psig (4.1 barg and 8.6 barg).
The Parker Balston Nitrogen Generator should be located in an area where the ambient tem-
perature is between 60°F and 100°F (16°C and 38°C). Installation of the nitrogen generator in an
area where the ambient temperature is not within the recommended range may adversely affect
the performance and/or life of the system or void the warranty. Install the generator in a location
which is protected from severe weather conditions, and is free from excessive ambient dust or dirt.
Compressed Air - The Parker Balston Nitrogen Generator requires a source of clean, dry com-
pressed air for optimal operation. The compressed air should be as close to instrument quality as
possible and supplied at a dewpoint less than or equal to 60°F (15°C), and at a pressure between
60 psig and 125 psig (4.1 barg and 8.6 barg). If the incoming air pressure is less than 60 psig (4.1
barg), an alarm will beep, and the system may go into a modified start-up mode (see "Pressure
Interruptions" for more details). The supply air should be at room temperature and relatively free
of water, compressor oil, hydrocarbons, and particulate matter. If the compressed air supply has
excessive oil and water carryover from the compressor, install a prefilter upstream from the gen-
erator (see Recommended Accessories section).
Chlorinated hydrocarbon compounds and chlorofluorocarbons (or freons) will permanently
contaminate the hydrocarbon catalyst module in the UHPN2-1100 UHP Nitrogen Generator. Ex-
treme care should be taken when specifying an air supply for the generator to ensure that these
compounds are not present in the air supply nor likely to get into the compressor providing air
to the generator.
The hydrocarbon catalyst module can also be contaminated by high concentrations of lead,
sulfur, or phosphorous compounds, heavy metals, and long chain polymers. Care should be
taken to avoid introducing these compounds into the Parker Balston UHPN2-1100 UHP Nitrogen
Generator. Specifically, assure that none of these compounds are stored near the inlet to the
compressor supplying the system with compressed air. The intake for the compressor should
be vented to the outdoors.
If any potentially damaging hydrocarbons, chlorofluorocarbons, chlorinated solvents or other
similar components are used in close proximity to the generator or to the compressed air sup-
ply, an auxiliary hydrocarbon scrubber (P/N 76080) should be installed directly upstream from the
generator.
The inlet air supply should be supplied by 1/4" or larger tubing. At least 1.5 SCFM (42 lpm) of
compressed air should be available for the generator to operate properly.
Power - The Parker Balston Nitrogen Generator may be operated by a 120 VAC or 230 VAC, 50/60
Hz power supply. Parker Hannifin recommends the use of a surge suppressor with the Nitro-
gen Generator to protect the unit from electrical surges and spikes and to maintain the product
warranty. The generator is shipped with a tag on the power receptacle which specifies the factory
setting of the voltage selector. For optimal performance of the generator, set the voltage selec-
tor to match the local power supply. (Note: The "NA" version of the generator is designed to run
only on 120 VAC power.) To change the setting on the voltage selector, simply remove the selec-
tor/fuse drawer from the receptacle using a small screwdriver, turn the selector so the desired
voltage shows in the window, and reassemble. To connect the generator to the power supply, plug
the female end of the electrical cord into the receptacle on the right side of the generator, and the
opposite end into a three-pronged earthed power receptacle. Main supply line voltage must be
within 10% of nominal rated voltage for the generator.
Before plugging power cord into power receptacle, check the voltage selector setting. The volt-
age setting must match the local power supply voltage.
Piping Components - The inlet and outlet ports for the Parker Balston Nitrogen Generator are
located on the right side of the unit (see Figure 1). The inlet port is 1/4" female NPT, and the cus-
tomer supplied inlet tubing and fittings should be clean and rated for 125 psig (8.6 barg).

To remove trace hydrocarbon contaminants from the inside surface of the downstream
(copper or stainless steel) tubing, the customer should clean the tubing prior to installa-
tion. First, connect the tubing to a supply of clean, inert gas (He or N2). Next, initiate the gas
flow through the tubing (5-10 cc/min.). Finally, heat the tubing with a propane torch, moving
the flame at a rate of approximately 1/2 in./sec. in the direction of flow. This procedure will
remove any trace waxes or oils used in the manufacture of the tubing.
Note: The use of plastic piping components or any piping components which are not clean
will contaminate the nitrogen stream.
If an indicating oxygen trap (P/N 72092) will be used with the generator, install the trap as
close to the outlet port of the generator as possible. Install the trap in a vertical position to
prevent channeling within the trap.
Drain Line - The 1/4" diameter plastic drain line attached to the compressed air prefilter is
coiled underneath the generator. Pipe the drain line to an appropriate disposal container.
The liquid in this drainage will consist of water and compressor oil which should be disposed
of properly.
Parker Hannifin strongly recommends installing a shutoff valve at the process or instrument
being supplied with nitrogen from the generator unless the process or instrument has its own
internal shutoff valve to isolate it from the nitrogen line.
A pressure regulator and flow controller, as detailed below, must be installed between the
generator and the point-of-use to maintain pressure, flow, and purity specifications. If both
of these control devices are incorporated into the downstream equipment being used, there
is no need to install them separately. These accessories must be appropriate for high purity
applications.
Pressure Regulator (downstream) - The nitrogen from the generator must be regulated
to the application pressure by installing a pressure regulator, specifically designed for high
purity applications, downstream from the generator.
Flow Controller - If the rated flow capacity of the generator is exceeded, the nitrogen purity
will be adversely affected. Specifically, the nitrogen stream will have increased levels of
oxygen, carbon dioxide and water vapor contamination. If the equipment or process used
downstream from the generator does not contain a flow control device, install a metering
valve (suitable for high purity applications), to set the nitrogen flow rate. The flow rate (at low
pressure) can be measured with a bubble-type digital flow meter.
All accessories recommended for use downstream from the Parker Balston Nitrogen Gen-
erator should be appropriate for high purity applications (see Figure 4).
Prefiltration - If instrument quality compressed air is not available, or if excess water drains
from the prefilter, the Balston 2002N-1B1-DX filter assembly should be installed, in series, on
the compressed air supply line, upstream from the generator.
Pressure Regulator (upstream) - To control the incoming air pressure to between 60 psig and
125 psig (4.1 barg and 8.6 barg), use a self-relieving pressure regulator. The Parker Balston
Pressure Regulator (P/N 72-130-V883) is a self-relieving pressure regulator with 1/2" NPT
inlet and outlet ports and a pressure gauge.
Recommended
Accessories
The outlet port is 1/8" female NPT. All tubing and fittings used downstream from the UHP
Nitrogen Generator should be stainless steel or refrigeration grade copper and rated for
125 psig (8.6 barg), minimally. Use only PTFE tape on all NPT fittings associated with the
generator. (Thread sealing compounds may contaminate the process stream.)

Startup
The Parker Balston UHP Nitrogen Generator requires five hours of warm-up time to achieve
rated purity.
Prior to shipment from the factory, the PSA towers are pressurized with high purity nitrogen
to prevent contamination from the atmosphere. The nitrogen is sealed into the towers by a
2-way valve directly upstream from the towers. Before starting the generator, remove the ser-
vice panel and open this 2-way valve (see Figure 5). Replace the service panel. There is also a
2-way (external) valve at the outlet of the generator. This valve must be closed at start-up and
remain closed until the 5 hour warm-up period is complete.
Open the inlet air supply valve (customer supplied) and turn the power switch (see Figure 1)
on the generator upward to the ON position. The “System Check” LED indicator will start
blinking once every 12 seconds. It will continue blinking during the warm-up period. The inlet
air pressure should be regulated to be between 60 psig and 125 psig (4.1 barg to 8.6 barg).
During the 5 hours of warm-up, there will be no flow of nitrogen from the generator.
Figure 5 - Manual Shut-Off Valve
Indicating Oxygen Trap - If visible verification of the purity of the nitrogen stream is desirable,
install an indicating oxygen trap downstream from the Nitrogen Generator. The Indicating
Oxygen Trap (P/N 72092) is a trace oxygen scrubber which provides a visible indication of
nitrogen purity downstream from the generator. The indicating trap should be installed in an
easily visible location downstream from the Nitrogen Generator. Install the oxygen trap in a
vertical position to reduce channeling within the trap. The freshly installed indicating trap is
green. As long as a portion of the trap remains green, the trap is still removing trace oxygen
impurities. The trap gradually changes color from green to brown as it becomes saturated
with oxygen. Replace the trap when more than half of it has been consumed (turned brown).
Note: Bypass oxygen trap until nitrogen is at specified purity and lines are purged.
Hydrocarbon Scrubber - The Parker Balston 76080 Hydrocarbon Scrubber is designed to
remove potentially damaging hydrocarbons and halogenated hydrocarbons from the com-
pressed air supply to the Parker Balston UHPN2-1100 UHP Nitrogen Generator.

After the initial start-up cycle (5 hours) has been completed, the “System Check” LED will go
off and the “System Ready” LED will illuminate. Open the external outlet valve and the gen-
erator will supply ultra high purity nitrogen to the application. Check all downstream piping
connections for leaks using a bubble-type leak detecting solution.
If there is a power or pressure interruption, the “System Check” LED will go on and the sys-
tem may go back into a start-up mode. (See “Power Interruptions” and “Pressure Interrup-
tions” sections below). If the “System Ready” LED indicator goes off and the “Service System”
LED indicator is illuminated or blinking, the operator should check the hydrocarbon catalyst
module (Model UHPN2-1100 only). It may need to be replaced as part of the normal mainte-
nance of the hydrocarbon catalyst module, or it may have a loose electrical connection (see
the Troubleshooting Section at the end of this bulletin).
If the compressed air pressure falls below 60 psig (4.1 barg), an internal pressure transducer
will activate an audible alarm and the yellow “System Check” light will be illuminated to
attract operator attention. If the pressure remains below 60 psig (4.1 barg) for less than 6
minutes (time required for purge and fill of PSA towers), the system will continue to operate
at rated flow and purity. If the inlet air pressure drops below 60 psig (4.1 barg) for more than
6 minutes, the internal outlet valve will close and the flow of nitrogen will cease. After this
low pressure condition is corrected, the outlet valve will open and the nitrogen flow will start
again immediately.
If the electrical power is interrupted for less than 30 minutes, the system will deliver nitro-
gen at rated flow and purity when the power returns. If the power is interrupted for between
30 and 60 minutes, the generator will go into an abbreviated 1 hour start-up cycle when the
power returns. If the power supply is interrupted for more than 1 hour, the initial 5 hour start-
up cycle will be repeated when the power returns.
The flow of nitrogen from the Parker Balston Nitrogen Generator must be controlled using
a metering valve or flow controller downstream from the unit. The flow control device may
be integral to the equipment being used downstream, or it may be an independent controller
(see Installation Section) purchased and installed by the customer. In either case, a device to
measure the flow should also be installed (either with the flow controller or downstream from
the application). If the demand of ultra high purity nitrogen exceeds the delivery capacity of
the generator, the purity and pressure of the emergent nitrogen stream will not meet specifi-
cations.
The outlet pressure and flow from the generator must be adjusted according to the operating
parameters listed below. If the outlet flow exceeds the rated flow for a given inlet pressure,
the nitrogen purity will not meet specifications.

If the generator will be shut down for longer than a few hours, turn off the power to the gen-
erator and close the (customer installed) inlet air valve. Allow the generator to purge for 10
minutes. Open the lower service panel and close the 2-way manual valve upstream from the
PSA towers (see Figure 5). Finally, close the external manual outlet valve. If the generator is
not shut down according to this procedure, the PSA towers may be poisoned and the war-
ranty will be void.

Allow at least 2 hours for the generator to cool prior to changing the catalyst module. The
hydrocarbon catalyst module in the Parker Balston Nitrogen Generator is located behind the
upper service panel and should be changed approximately every three years (or when the
“Service System” LED starts blinking) to maintain the hydrocarbon removal specification for
the unit.
Catalyst Module
Maintenance
(Model UHPN2-1100 only)
Before servicing the Parker Balston Nitrogen Generator, isolate the unit from the com-
pressed air and electrical power supplies. Allow the generator to cool for at least 2 hours
before depressurizing (Model UHPN2-1100 only). All maintenance tasks for the Parker
Balston Nitrogen Generator should be performed by suitable personnel using reasonable
care.
The primary maintenance tasks required by the Parker Balston Nitrogen Generator are
changing the filter cartridges in the coalescing prefilter and particulate filters (annually), re-
placing the final membrane filter cartridge (annually), and replacing the hydrocarbon catalyst
module (Model UHPN2-1100 only, 3 years). A summary of the replacement part numbers and
recommended service frequency is shown at the end of this Maintenance section. See Figure
6 for the locations of the various maintenance items.
Additional coalescing prefilter cartridges, particulate filter cartridges, and membrane filter
cartridges for the Parker Balston HPN2-1100 and UHPN2-1100 Nitrogen Generators may
be ordered through your local representative. For convenience, a one-year supply of these
replacement cartridges has been assembled into a maintenance kit (MK7692 Maintenance Kit
for Model HPN2-1100 and MK7694 Maintenance Kit for Model UHPN2-1100).
If necessary, the Nitrogen Generator may be wiped clean with a dry cloth on an as needed
basis. Do not use water, aerosols, or other cleaning agents to clean the unit. The use of any
liquid detergent to clean the generator could present an electrical hazard.
If the hydrocarbon catalyst module is not being replaced when the filters are replaced, there
is no need to allow the generator to cool. The only preparation needed to service the filters
is turning off the air supply to the generator and depressurizing the affected filter hous-
ings. To depressurize the filter housings, turn off the compressed air supply to the generator
and allow the generator to cycle until the inlet pressure displays zero. This should only take
10 minutes (1-2 generator cycles). Turn off power to generator.
The coalescing and particulate filters and the final membrane filter in the Nitrogen Generator
are easily accessible when the lower service panel is removed (see Figure 6). These filters
should be changed on an annual basis to maintain efficient operation of the system. The filter
cartridge in the coalescing prefilter assembly is removed by loosening the bowl from the filter
assembly, and unscrewing the element retainer from the base of the cartridge. Insert the
new filter cartridge (P/N 100-12-BX) and reassemble the housing in the reverse order.
The particulate filter(s) and final membrane filter cartridges are easily removed from the
housing by unscrewing the filter bowl from the filter head (no tools required). Insert the new
filter cartridge (P/N 050-05-BX or GS050-05-95) and reassemble the filter housing.
Replace the lower service panel after replacing the filter cartridges. The time required to
service all stages of filtration integral to the generator is approximately 30 minutes.

Occasionally, one or both of the fuses in the UHP Nitrogen Generator may burn out. The fuse
located in the hydrocarbon removal module power harness is rated for 50 mA. This is not a field-
serviceable fuse and should not be removed under any circumstances. The main fuses are located
in the power receptacle on the side of the generator. Before servicing the main fuses, turn the
generator off and disconnect the power cord from both the power supply and the generator power
receptacle.
To access the main fuses, use a small screwdriver to remove the fuse holder located in the power
receptacle of the generator. In the UHP Nitrogen Generator, both the phase and neutral are fused
separately. As a result of these configuration, both fuses should be checked any time fuse replace-
ment is warranted. Replace either one or both fuses as necessary and re-assemble. To maintain
the safety and performance integrity of the product, use only fuses of the size and type detailed in
the specifications section of this bulletin.
This equipment has main fuses in both neutral and phase lines. Use care when servicing.

The tools required to change the catalyst module are: a Phillips head screwdriver, two 9/16"
wrenches (or adjustable wrenches), and one 1/2" wrench (or adjustable). The procedure for re-
placing the hydrocarbon catalyst module is as follows:
1Turn off the inlet air supply to the generator. Wait approximately 10 minutes before turning
the generator power off. This will allow the generator to depressurize fully.
2Unplug the generator from the power receptacle. Allow the unit to cool for at least 2 hours
before removing the cover.
3Remove the upper and lower service panels from the UHPN2-1100 (4 Phillips screws) and
disconnect the electrical fittings to the hydrocarbon catalyst module at the connectors (see
Figure 6).
4Disconnect the two tubing connections to the hydrocarbon catalyst module (see Figure 6) us-
ing the wrenches (one as an anchor).
5Remove the two screws which fasten the hydrocarbon catalyst module to the UHPN2-1100
frame.
6Remove the spent module from the UHPN2-1100 and replace with the new module.
7Re-connect the inlet and outlet fittings to the hydrocarbon catalyst module, open the supply
air valve, and check for leaks. Re-connect the module's electrical connections. Replace the
service panels. Plug the generator back into the wall receptacle.
8Restart the UHPN2-1100 by switching the power on. The generator will begin its 5 hour
warm-up.

Notes
1The Parker Balston Nitrogen Generator
was designed to meet the specications
listed when operated in a manner consis-
tent with the recommendations presented
in this manual. If these operating speci-
cations are not met, then inferior product
performance and shortened product life
may result.
2The nitrogen generator should be run
continuously to optimize the performance
and reliability of the unit.
4The Parker Balston Nitrogen Generator
installation should be thoroughly checked
for leaks after any service activity has been
performed on the system in particular or its
installation on the whole. Any leak could
signicantly reduce the purity of the outlet
nitrogen stream.
5The Parker Balston Nitrogen Generator will
not operate with an inlet air pressure less
than 60 psig (4.1 barg). A pressure regulator
must be installed upstream from the gen-
erator to maintain an air supply pressure
of 60 psig to 125 psig (4.1 barg to 8.6
barg).

Nitrogen is nontoxic and largely inert. It can act as a simple asphyxiant by displacing oxy-
gen in air. Inhalation of nitrogen in excessive concentrations can result in unconsciousness
without any warning symptoms such as dizziness, fatigue, etc.
