NitroFlow TG2 Generator Series
Figure 1 NitroFlow TG2 Nitrogen Generator
The integrated system is engineered to produce pure nitrogen gas, hydrocarbon free air, and
clean, dry -40°F dew point air delivered by a carefully matched scroll compressor. The system is
housed in two fully integrated cabinets: the lower cabinet produces the compressed air using an
oil-less rotary scroll compressor. The upper cabinet separates the compressed air into the three
gases: nitrogen, and hydrocarbon free dry air.
General Description
The generator is certied to the electrical safety requirements as specied by the IEC, UL,
and CSA standards. These units bear the CSA marking on the product. Product supplied
internationally also carries the CE mark. The product meets EMC compliance. Internal pressure
receivers are CRN and ASTM certied or CE certied.
Regulatory
Compliance
The Nitroow TG2 generator contains the necessary components to produce hydrocarbon free,
dry air and nitrogen. The ow schematics (Figure 2A and 2B) show all of the major components of
the system. The system can be broken down into 7 stages: compressed air, liquid water removal,
pre-ltration, oxygen/water vapor removal, hydrocarbon removal, water vapor removal, and nal
ltration.

The design of the oil-less rotary scroll compressor offers high reliability and quiet operation. The
scroll consists of two sets of identical spirals that are offset 180 degrees from each other. As one
scroll orbits around the other xed scroll, air is trapped, compressed, and is then directed into the
center where it is discharged from the pump.
A high output fan cools the compressor cabinet as it blows over a series of ns on the after-
cooler. The compressor operates at a lower temperature, thus increasing bearing, tip seal, and
grease life. As the fan blows across the after-cooler, the air temperature is decreased and water
is condensed in both the after-cooler and in the receiver tank. The water is discharged through
the automatic electric drain valve that is connected to a disposal container.

The NitroFlow TG2 generator incorporates a water separator to remove liquid water from the
compressed air before it reaches the prelters. The liquids are collected in the supplied disposal
container. Refer to the included installation and maintenance instructions.
Two stages of high efciency coalescing pre-lters are incorporated into the design of the Nitroow
TG2 to remove water and particulate contamination to 0.1 micron. The generator is equipped with
oat drain valves to automatically discharge any liquids which have accumulated in the lter bowls.
The liquids are collected in the supplied disposal container. These lters protect the membrane
and associated components from contamination.
A 3-way pneumatic valve is located after the prelters to release any leftover liquid water that may
be present on startup.
An activated carbon module is located upstream of both the nitrogen module and the dryer module
to remove any hydrocarbon contaminants that may exist in the room air. A particulate lter is
located after this carbon module to remove any carbon particles.
The NitroFlow TG2 generator has a hollow ber membrane module which converts compressed
air into high purity nitrogen. The membrane module has no moving parts assuring years of
maintenance-free operation.
There is one activated carbon module and particulate lter after the nitrogen membrane to remove
any contaminants present in the nitrogen stream.
The water vapor in the compressed air passes through the hollow bers of the membrane for
removal, resulting in dry air. A small portion of the dry air is redirected along the bers to sweep out
additional water vapor laden air and vented to atmosphere in the cabinet. A dew point of -40°F is
achieved at a pressure of 100 psig.
An activated carbon module is located downstream of the membrane dryer to remove any volatile
organic compounds that may be present in the air stream. A lter is located after this carbon
module to remove any carbon particles.

Diagnostics
Figure 3 Figure 4
There are two diagnostic indicator lights on the Parker Balston NitroFlow TG2 System:
High Temperature LED (red): The “High Temperature” LED indicator illuminates when the
compressor pump has reached its maximum temperature. The compressor will shut down by a
thermal switch opening, preventing power to the motor. Compressor restarts automatically as
soon as the over-temperature condition is corrected.
Power On LED (Green): This indicates the compressor is operating.
Installation
All installation, operation, and maintenance activities for the NitroFlowTG2 Generator System
should be performed by trained personnel using reasonable care to avoid injury or damage.
The NitroFlow TG2 system has casters and is packed in a wooden shipping container. The
installation kit, consisting of plastic tubing, tube ttings, and a plug is packed in a box inside
the wooden container. Remove the wire L-shaped fasteners from the sides of the container
(see Figure 3). Do not attempt to lift the generator from the container. Remove and locate the
plywood ramp (see Figure 4). Release the locked casters. Move the generator down the ramp.
Move the generator and installation kit to its installation location.

Location of the generator with proper ventilation is critical. Install the generator in a clean, well
ventilated area. To provide adequate ventilation and servicing for the generator, a minimum
clearance distance of 30 inches in front and in the rear is required (see Figure 5). Fresh intake
ventilation for the generator enters from the bottom and sides, while warm exhaust air exits from
the right, rear side. A minimum of 3 inches clearance is required on both sides of the generator
(see Figure 6).
For the NA Model: The NitroFlow TG2 Generator Series requires one electrical power outlet: a
dedicated grounded 208 to 254VAC, 60Hz, single phase, minimum 30Amp circuit breaker with a
NEMA 6-30R or L6-30R receptacle (see Figure 7). Parker requires purchasing a step-down
transformer if your facility voltage is 255 or higher or a step-up transformer if your voltage
decreases below 208VAC. See the accessory section on page 17. Main supply voltage
uctuations must be within ±10% of the nominal main supply voltage.
For the JA and WD Models: The NitroFlow TG2 Generator Series, rated at 230V, 50 Hz, single
phase, 13A fully loaded installation requires the following electrical setup:
1The supply line should be dedicated to the generator. No other equipment should operate
using the same line.
2The service should be capable of carrying 20 amperes. The wire gauge should be sized
accordingly.
3The service should be protected by up to a minimum 20 Amp circuit breaker. The value
is based on the application/equipment requirements as well as the electrical components’
tolerance and uncontrollable external variables.
The generator is for indoor use only. Do not install outdoors. The generator must be
installed in a climate controlled room. The ambient temperature of the air surrounding the
generator should not exceed 85°F (29°C) or be below 60°F (16°C). The relative humidity of
the ambient should not exceed 43% at 85°F. Do not locate the generator where hot exhaust
air from other heat generating sources may be drawn into the generator. The area should be
free of excessive dust, toxic or ammable gases, solvent fumes, and moisture. An exhaust vent
attachment is available to route exhaust away from the generator(see Figure 5). The diameter of
the exhaust vent ducting must be six inches. An in-line duct fan, capable of exhausting 226 CFM,
is required for ducting greater than 15 feet. See Accessory Parts table on Page 17 for details.
The Parker Balston NitroFlow TG2 Generator Series creates minimal noise during operation. The
noise generated is about 49dB at one meter. Periodically there is an air discharge noise from the
drain port eliminating accumulated uids in the prelters and receiver tank. The noise and heat
generated by the unit should be considered when selecting an installation location. A silencer
kit is included for the drain discharge noise. There is also a pump “burp” noise lasting a few
seconds each time the generator is shut down. This is the compressor depressurizing the pump
during shutdown.

Generator Controls
Check that the power cord of the generator is properly connected to the generator receptacle.
Rotate clockwise to lock. Check that the power cord of the generator is connected to the proper
power supply outlet.
During normal operation, the generator’s power switch is illuminated green. The compressor
pressure gauge indicates a pressure between 125 to 130 psig (8.6 to 8.9 barg). If the pressure
drops below 125 psi, then the outlet ow is too high. Set the 3 regulators to the specied values
by the instrument. The ow rate for each gas is displayed by the ow meter designated for each
gas. Refer to the ow label on the top of the NitroFlow TG2 cabinet for the correct ow reading at
standard conditions. Do not remove the cover while the system is pressurized.
The generator has its own automatic water drain system. The 3 lters located on the back of
the generator are equipped with pneumatic drains that open when the water level reaches a
predetermined point. The compressor drain operates every 10 minutes, opens for 2 seconds; the
two internal lter bowls also drain every 10 minutes.
The generator cabinet has two LED indicators (see Figure 9): Power ON, and High Temperature.
The green LED remains illuminated during normal operation. The other LED indicator,
“High Temperature” remains unlit if the compressor is functioning properly. Red illumination
of the High Temperature LED signals a fault condition and warns the operator that the unit
requires servicing.
Ensure all 3 gas outlets at the back of the generator are not connected to pipework and are closed
using the yellow shut off valves on the back of the NitroFlow TG2. Rotate the Power Switch on
the front panel of the generator (see gure 9) to ON by turning it clockwise. The generator will start
and the green LED will illuminate. The Compressor Output pressure gauge will slowly increase to a
maximum set pressure of 137psig (9.4 barg). Full pressurization will occur within 10 minutes. Allow
the system to run for 90 minutes to reach full operating temperature. Using the regulators on the
front of the unit, adjust the outlet pressure on each gas line to 20psi and open the 3 gas outlets slightly
using the yellow shut off valves at the back of the generator allowing the system to vent to atmosphere
for approximately 1 hour (note: venting to atmosphere at 20psi is not too loud and will allow the
desired purge. Opening the valves fully will “overow” the generator and it will not maintain pressure).
Connect the gas lines to the back of the generator and allow them to purge the length of pipework to
atmosphere for another 15 minutes. Close the 3 gas outlets using the yellow shut off valves. Connect
the now purged lines to the application and slowly re-open the yellow shut off valves to pressurize
the gas lines. This procedure should also be followed any time the generator is fully up to
operating temperature and then powered off for more than 30 minutes.

If the compressed air pressure decreases less than 90 psig (6.2 barg), the nitrogen output purity
level will decrease. Once pressure is restored, purity level will be restored.
The compressor inlet pressure gauge indicates the range of system pressure during operation,
normally between 125 psig and 130 psig.
See the Troubleshooting section of this manual on pages 17-20 to resolve any abnormal or faulty
conditions.
If the electrical power is interrupted, the generator will start automatically when power returns.
Please see Start-up/Restart procedure on previous page.
For normal or emergency shutdown, pull out the plug on the cordset to disconnect the main
power (see Figure 1). Full depressurization takes 1 hour. Do not remove cover while system
is pressurized.
Maintenance tasks for the NitroFlow TG2 Generator should be performed by trained personnel
familiar with the service and safety precautions of electromechanical devices to avoid injury
or damage. Safety risks that may affect the service personnel are identied with the
necessary protective measures described.
Parker highly recommends service be performed by a Parker trained technician only. Call
the factory about PMP, the Preventative Maintenance Program. The service personnel will
verify the safe state of the generator after the maintenance or repair is completed.
Prior to servicing the generator, turn off the system and disconnect the cordset from the power
supply. Allow the system a minimum of 1 hour to depressurize. See shutdown section above.
To ensure product performance and reliability, periodic preventative maintenance must be
performed. The three tables on page 10 detail the maintenance schedules for both the
compressor and purication components, as well as the part numbers for replacement parts and
maintenance kits.

System Specifications
Cautions 1The generator should be installed in an area with adequate ventilation to reduce the
ammability of the oxygen-rich permeate stream. The system should not be located in an
area where the permeate stream poses the risk of explosion or combustion
2Nitrogen is nontoxic and largely inert. It can act as a simple asphyxiant by displacing
oxygen in air. Inhalation of nitrogen in excessive concentrations can result in
unconsciousness without any warning symptoms such as dizziness and fatigue.
3 The maximum operating pressure of the system is 137 psig (9.4 barg). Operating the
generator at pressures above 137 psig (9.4 barg) will result in damage to the pump and
membrane.
4 The drain lines should be piped away to the provided collection container (open to
atmospheric pressure) to avoid any possible re-entrainment of liquid in the air which feeds
the generator.
5 Changes in inlet pressure or outlet ow demand will alter the gas purity.
6Install the generator in a room where the ambient temperature and humidity are below
85°F at 43% RH.

Disconnect the electrical power and depressurize the generator before
attempting any troubleshooting activities according to the shut down steps in
the operation section. Only trained personnel using reasonable care should
perform any troubleshooting activities.
Determine whether the trouble is with the compressor or the gas generator.
Disconnect the plastic tubing from the compressor tting (see Figure 43). Once
removed, place supplied plug into tting. Check that the compressed air source
builds full pressure and cycles off within two minutes.
If the compressor air supply is conrmed, remove lower side panel and relieve tank
pressure using auto tank drain test button. Proceed to the NitroFlow TG2 generator
Troubleshooting section (page 20), and begin troubleshooting the NitroFlow TG2
generator. Otherwise, refer to the Compressor Troubleshooting section (pages 19,
20), and begin troubleshooting the compressor.
