The Balston Nitrogen Generator is a completely engineered system which will convert a com-
pressed air supply into 95% to 99% purity compressed nitrogen and (optionally) monitor the purity
of the emergent nitrogen stream. The system is based on state-of-the-art membrane separation
technology. Hollow fiber membranes are used to separate air into a concentrated nitrogen output
stream and an oxygen enriched permeate stream. To monitor the purity of the nitrogen stream,
Parker has incorporated an oxygen analyzer into the design of its HFX0-3 Nitrogen Generation
System.
The Balston HFX0-3 Nitrogen Generator has been certified to IEC 1010 Standards (CSA 22.2
No. 1010.1-92). These generators bear the CSA safety marking on the product label.
The Balston HFX and HFX0-3 Nitrogen Generators include all the components required to generate
high purity nitrogen from compressed air and monitor the purity of that nitrogen (see Figure 1). The
flow schematic (Figure 2) shows all of the major components of the system. The system can be
broken down into five primary functional groups. These are: prefiltration, air separation, controls,
final filtration, and nitrogen purity monitoring (Model HFX0-3 only). An oxygen analyzer is also
available as a separate accessory for the HFX-3 (P/N 72-730).

Description
Prefiltration Two stages of coalescing prefiltration are incorporated into the Balston HFX-3 and HFX0-3 Nitrogen
Generator to protect the membrane module from contamination. These filters are located behind the
filtration access panel, and they remove liquids and particulate matter from the incoming air supply.
The filters are equipped with float drains which automatically open to empty any liquids accumulated
inside the filter housing. The drains are connected to 1/4" O.D. plastic tubing which discharges to
atmosphere at the back of the nitrogen generator (see Figure 1).
Air separation takes place in the membrane module. This module consists of bundles of hollow fiber
membranes. The compressed air enters the center bore of these fibers and travels the length of the
fibers. As the air passes through these hollow fibers, oxygen and water molecules pass through the
membrane wall at a higher rate than nitrogen molecules. The result is a high purity, dry nitrogen gas
exiting the membrane module through the outlet. The oxygen enriched permeate stream exits the
membrane module through ports on the side of the module at a very low pressure.
Final filtration consists of a .01 micron (absolute) membrane filter. The final membrane filter will assure
the user a clean, commercially sterile supply of high purity nitrogen.

Oxygen Monitoring
Controls The controls in the Balston Nitrogen Generator comprise: an operating pressure gage, a
flowmeter, a flow control valve, an outlet pressure gauge, and a pressure regulator (see Figure
1). Proper use of these controls will assure the user of a 95% to 99% nitrogen outlet stream,
depending on operating pressure and flow rate. The pressure gages, which are mounted on the
front panel, measure operating pressure and outlet pressure. The flowmeter measures the flow
rate of nitrogen exiting the membrane module. The scale on this flowmeter is dimensionless
because the operating pressure can range from 60 psig to 145 psig (4.1 barg to 10 barg). The
Nitrogen Purity Label on the control panel is used to convert this dimensionless flowmeter
reading to standard cubic feet per hour (or liters per minute), based on inlet air pressure and
required purity. The flow control valve is used to set the flow rate through the system as
determined by the user’s required nitrogen purity. The outlet pressure regulator allows the user
to set the pressure of the nitrogen process stream.

An oxygen analyzer has been incorporated into the design of the HFX0-3 Nitrogen Generator to
monitor the oxygen content of the nitrogen process stream. The unit is powered by a 120 VAC
or 240 VAC, 50/60 Hz power supply. The sensing device in the oxygen analyzer is a galvanic
cell. The analyzer has an internal temperature compensation circuit to provide accurate read-
ings within a specified temperature range.
The oxygen analyzer has all the controls necessary to assure safe and accurate monitoring of
the oxygen concentration in a process stream. The analyzer is equipped with the following
controls and features (see Figure 3):

tion gas is 1/8" NPT and is located on the back of the generator, as shown in Figure 1. The
switch located below the calibration port (see Figure 1) is toggled up for calibration and down for
nitrogen purity monitoring.

Compressed Air - The Balston HFX-3 and HFX0-3 Nitrogen Generators require a source of clean,
dry compressed air for operation. The incoming air should be between 60°F and 95°F(15°C and
35°C), have a dewpoint less than the ambient temperature, and be relatively free of water, compres-
sor oil, hydrocarbons, and particulate matter. The inlet pressure of the compressed air supply
should be regulated to 60 psig to 145 psig (4.1 barg to 10 barg).

In many applications, the process flow requirements for nitrogen fluctuate with time. As noted
earlier, if the flowrate of the emergent nitrogen stream varies, the purity level of the nitrogen stream
also varies; therefore, it is important to keep the nitrogen flow as constant as possible. A receiving
tank can be installed between the nitrogen generator and the process to accommodate fluctuations
in nitrogen demand and maintain nitrogen purity.
If a receiving tank is to be used, a back pressure regulator and a check valve should be installed
between the Balston Nitrogen Generator and the receiver tank (see Figure 5). The 72-460 Back
Pressure Controller contains both of these components and may be ordered as an accessory for the
Nitrogen Generator. The adjustable back pressure regulator, when set to the appropriate pressure,
will maintain a constant pressure drop across the flow control valve. By controlling the pressure
drop across the flow control valve, the nitrogen flow will be kept constant and the variability in purity
of the nitrogen process stream will be minimized. The check valve, when installed properly, will
prevent any flow of nitrogen from the receiver upstream toward the generator, providing a more
effective means of storing the emergent nitrogen.

Alarm Relay Contacts
The high and low limits of the alarm may be set anywhere between 0.5% and 25% oxygen,
depending on the process limitations. To set the high alarm set point, press the alarm set switch
upward and simultaneously adjust the high potentiometer until the display shows the desired high
alarm set point. To set the low alarm set point, press the alarm set switch downward and simulta-
neously adjust the low potentiometer until the display shows the desired low alarm set point.
The oxygen analyzer also includes high and low alarm relay contacts located inside the service
panel. The oxygen analyzer, through the use of the alarm relay contacts, may be used to control
the process stream (see Figure 6). For example, a high or low oxygen concentration could signal
a remote alarm, open a backup supply of the process stream, or close the process down for
protection of downstream equipment or processes. The alarm relay contacts should be wired by a
qualified electrician. Both the high and low oxygen alarm conditions are provided with three relay
outputs: a common (C), a normally open (NO), and normally closed (NC).

Note: There is no power switch on the genera-
tor. The oxygen analyzer is energized when the generator is plugged in.)
The inlet and outlet connections to the Balston HFX0-3 Nitrogen Generator must be checked for leaks
prior to system start-up. After the system is properly installed and checked for leaks, the inlet gate
valve can be opened to introduce compressed air to the system.
During start-up and adjustment of the system, the nitrogen produced by the system will vary in purity.
If the application for the nitrogen is critically dependent on purity, the nitrogen produced during start-up
or adjustment should be vented.
If the outlet nitrogen flow is closed, the system will still consume compressed air. The inlet air is simply
vented to atmosphere through the permeate ports of the membrane module.

The oxygen analyzer is calibrated prior to shipment; however, Parker strongly recommends re-
calibrating the unit prior to initial start-up. After the initial start-up, the analyzer should be calibrated on
a bi-weekly basis until a suitable schedule is determined, based upon the level of accuracy required by
the application.
There are two methods of calibrating the oxygen analyzer: the two point method and the single point
method. In the two point method, the first point in the calibration range is set to zero using a zero gas
(zero percent oxygen), and the second point in the range is set to a known percentage of oxygen using
a span gas (known quantity of oxygen, per gas supplier) or compressed air (20.9% oxygen). In the
single point method, only one point in the calibration range is set, using either span gas or compressed
air. Maximum accuracy in oxygen concentration monitoring will be achieved if the oxygen concentra-
tion in the span gas is within the range of the expected oxygen concentration in the process stream
and the pressure of the gas closely approximates the pressure of the nitrogen gas (See Figure 3 for
calibration controls).

Elevated Pressure
Applications
(>10 psig/0.7 barg)
The user must determine the nitrogen purity, flow rate, and pressure required by the application
prior to adjusting the system for desired outlet nitrogen purity and flow rate. The inlet air pressure
must be constant in order for the system to supply nitrogen of consistent purity to the application.
The inlet pressure to the Balston Nitrogen Generator should be maximized (within process and
generator parameters) to optimize the operation of the membrane module. The required inlet air
flow rate and all flow and purity specifications for different operating conditions are shown in the
specifications listing on pages 12-13.
Flow adjustments are made according to the values on the Nitrogen Purity label attached to the
front of the generator (and shown below).
If the Balston Nitrogen Generator is being used to deliver nitrogen at or near atmospheric pressure
(e.g. purging or blanketing applications), use the following procedure for start-up and adjustment of
the system.
11
11
1 Open the (customer installed) inlet air gate valve.
22
22
2 Adjust the (customer installed) inlet air pressure regulator until the Operating Pressure Gauge
(see Figure 1) shows the pressure reading required to achieve the purity and flow to match the
application (see Purity/Flow label above).
33
33
3 Adjust the Outlet Pressure Regulator (see Figure 1) until the Outlet Pressure Gauge reads less
than 10 psig (0.7 barg).
44
44
4 Consult the Nitrogen Purity Label on the control panel of the generator to determine the proper
flowmeter setting for the required process nitrogen purity and inlet air pressure. Adjust the flow
control valve on the control panel (see Figure 1) to yield the proper flowmeter reading.
55
55
5 Allow the system to reach equilibrium at the desired flowrate, pressure, and purity parameters.
This should take approximately 15 minutes.
66
66
6 Check the purity readings on the oxygen analyzer on a routine basis. If the nitrogen purity level
falls below the desired level, readjust the flow control valve until the proper nitrogen purity level is
reached. (Note: If more than minor adjustments of the flow control valve are required to reach
the desired purity level, please see the Troubleshooting section of this manual for further guid-
ance.)
If the Balston Nitrogen Generator is being used to deliver nitrogen at an elevated pressure
(>10 psig/0.7 barg), use the following procedure for start-up and adjustment of the system. (Note:
In elevated pressure applications, the customer should install a flow controller downstream from the
Nitrogen Generator.)
11
11
1 Open the (customer installed) inlet air gate valve.
22
22
2 Adjust the (customer installed) inlet air pressure regulator until the Operating Pressure gauge
(see Figure 1) shows the pressure reading required to achieve the purity and flow to match the
application (see Purity/Flow label, page 13).
33
33
3 Turn the Flow Control Valve to its fully open position
44
44
4 Set the Outlet Pressure Regulator (see Figure 1) to the desired outlet nitrogen pressure.
55
55
5 Consult the Nitrogen Purity Label on the control panel of the HFX0-3 to determine the proper
dimensionless flowmeter setting for the required process nitrogen purity and operating air
pressure. Adjust the (customer installed) flow controller until the dimensionless flowmeter shows
the correct reading (based on the Nitrogen Purity Label).
66
66
6 Allow the system to reach equilibrium at the desired flowrate, pressure, and purity parameters.
This should take approximately 15 minutes.
77
77
7 Check the purity readings on the oxygen analyzer on a routine basis. If the nitrogen purity level
falls below the desired level, readjust the downstream flow controller until the proper nitrogen
purity level is reached. (Note: If more than minor adjustments of the downstream flow controller
are required to reach the desired purity level, please see the Troubleshooting section of this
manual for further guidance.)

After all the components have been properly installed (see Figure 5), the following procedure should
be followed to ensure optimal operation of the entire nitrogen supply system.
11
11
1 Set the inlet pressure to the Balston Nitrogen Generator using the customer-provided pressure
regulator, and initiate the air flow through the system.
22
22
2 Set the flow control valve to its fully open position. The nitrogen flow meter reading should be at
the top of the scale.
33
33
3 Close the shut-off valve to the process and open the vent valve downstream from the receiving
tank to prevent substandard nitrogen from entering the process.
44
44
4 Fully open the outlet pressure regulator on the nitrogen generator, and adjust the back pressure
controller until the outlet pressure gauge on the nitrogen generator reads 10 psig (0.7 bar) less
than the desired nitrogen storage pressure. Maximize the storage pressure to minimize the size
of the receiving tank needed.
55
55
5 Set the flow control valve on the front panel of the nitrogen generator to the proper reading, as
specified by the Nitrogen Purity Label. Read from the middle of the ball.
66
66
6 Purge the entire system for 5 minutes, venting the initial nitrogen stream through the vent valve
to atmosphere.
77
77
7 Close the vent valve, open the process shut-off valve, and initiate the flow of nitrogen to the
process.
The use of a receiving tank upstream from the process, as detailed in this literature, significantly
reduces the effects of fluctuating nitrogen demand on the purity of the emergent nitrogen process
stream from the Balston Nitrogen Generator. Parker recommends a 5 minute purge of the system
(see Step 3 above) each time the unit is started.
If the temperature of the inlet air to the Balston Nitrogen Generator differs from the temperature of
the module (i.e. ambient temperature), the system must be allowed to reach temperature equilibrium
before a constant purity of nitrogen is delivered from the system. If the temperature difference is
10°F-20°F (5°C-11°C), this equilibrium period may be as long as 60 minutes. The inlet air tempera-
ture and, more importantly, inlet air dewpoint, must not be higher than the temperature of the system
or condensation of water within the system may occur, resulting in inefficient performance of the
system and/or damage to the membrane.
Performance of the Balston Nitrogen Generator is highly dependent on the temperature of the inlet
air. The data on purity and flow rate presented in this bulletin is based on an inlet air temperature of
68°F (20°C). If the temperature of the inlet air at the point of use for this system varies from 68°F
(20°C) by more than 5°F (3°C), the factory must be consulted for flow and purity information.
The optimum performance of the Balston Nitrogen Generator is dependent on system parameters
remaining stable and accurate; therefore, the system should be checked at least once per week.
This routine system check should include correcting any changes in the flowmeter reading, confirm-
ing pressure gauge reading stability and operating pressure setting, checking the downstream
flowmeter (if applicable) to ensure flows are consistent with the required nitrogen purity level, and
calibrating the oxygen analyzer.
System upsets relative to pressure or flow rate will result in variations in purity of the outlet gas.
System upsets relative to temperature, dewpoint, or hydrocarbon content of the inlet compressed air
may result in variations of the system performance. These types of upsets should be eliminated
from the compressed air delivery system to assure consistent performance of the Balston Nitrogen
Generator.
Proper shutdown of the Balston Nitrogen Generator can be accomplished by simply closing the inlet
air gate valve and turning off the oxygen analyzer. If the inlet valve is left open, the system will
continue to consume inlet compressed air. Closing the outlet flow control valve will not prevent air
consumption because the membrane module permeate ports are open to atmosphere.

Required maintenance for the Balston Nitrogen Generation System consists of changing the prefilter
and final filter cartridges (annually), changing the galvanic cell in the oxygen analyzer (annually),
checking the performance of the system, and calibrating the oxygen analyzer. The recommended
service schedule and replacement part numbers are outlined at the end of this section. The calibra-
tion procedure for the oxygen analyzer is outlined on page 6. The analyzer should be calibrated on
a regular basis, as dictated by the application.
Changing filter cartridges more frequently will translate into direct energy savings and reduced
operating costs. Annual electricity costs to operate a typical 100 HP compressor can be as high as
$50,000. Pressure drop in the system adds to this expense. A system operating at 100 psig that is
exeriencing a 2 psig pressure drop through a filter, requires an additional 1% in operating energy
costs or approximately $500.00+ per year.
Replacement prefilter cartridges, final membrane filter cartridges, and galvanic cells may be ordered
through your local representative. For convenience, these replacement items have been packaged
into a maintenance kit for each generator. Maintenance Kits provide a 6 month supply of filtration
replacement components.
The only tools required to change the prefilter cartridges and the final membrane filter cartridge is a
Phillips head screwdriver. All filter housings which require routine service are easily accessible
when the front filtration access panel is opened. (Remove the four corner screws.) The two coalesc-
ing prefilters are Balston 2002N-1B1-DX and 2002N-1B1-BX filter assemblies (see Figure 7). Re-
place these filter cartridges with Balston 100-12-DX and 100-12-BX filter cartridges. When replacing
the prefilter cartridges, be sure to install the proper grade filter in the proper housing (the housings
are labeled). The final membrane filter is a Balston 2002N-0A0-95 filter assembly. Replace this
membrane filter cartridge with a Balston Grade GS 100-12-95 membrane filter cartridge.
The filter cartridges in the filter assemblies are removed by: twisting the filter bowl clockwise 1/8 of a
turn while pushing up gently, lowering the filter bowl away from the filter head, and unscrewing the
element retainer from the base of the cartridge. Insert the new filter cartridge and reassemble the
housing in reverse order.
The time required to service all three stages of filtration is less than 15 minutes.
