Operation Manual Nitropac N01x – N06x

Introduction
The Donaldson Nitropac Generator is designed to cater for a wide variety of industrial and
scientific applications. Your generator will have been carefully selected to meet your specific
pressure, flow, and purity requirements, if you have any questions regarding the sizing of your
system please do not hesitate to contact Donaldson.

Technical Description
Basic concept
A modular range of Carbon Molecular Sieve (CMS) nitrogen gas generators. The generators
operate using Pressure Swing Adsorption (PSA). This is where the product contains two separate
containers or “beds” of granular carbon pellets.
The unit requires a compressed air supply to operate, ultimately it is akin to many standard air
filtration / drying products. The inlet compressed air is passed into the first “bed”, as the air
passes across the carbon bed the oxygen is adsorbed, allowing the nitrogen in the compressed
air to carry on through the bed for collection and further use. After a certain time the online bed of
carbon will become saturated with oxygen. At this point in time, the control system will operate
various valves to bring the second bed of carbon on line. As the second bed comes on line the
first bed is vented to atmosphere to release the adsorbed oxygen and regenerate the bed ready
to be re-used again. This cycle will continue to repeat until the user stops consuming nitrogen.
Should the demand for Nitrogen be less than the rated output flow, or indeed should the demand
stop the generator will automatically go into ECO Mode and the front panel LED will illuminate. In
ECO mode the changeover of the columns is suspended which will stop the consumption of inlet
compressed air. The control system will automatically detect when the demand for Nitrogen
resumes and the generator will start to produce Nitrogen again.

Installation
It is the user/installer’s responsibility to ensure that the generator is located and
protected against any external influences such as vibration, shock, wind, snow
loading, earthquake or fire. The installation should conform to all local regulations
and should be leak tight and completed by technically competent personnel.

Final Location of the generator should be carefully considered, the largest model in the range will
weight 622 kg / 1368 lbs. Equipment is only to be installed on floor with a weight rating of min
1000kg/m2 or 200 lbs per Sq.ft.
Once in position the foot plate of the generator should be secured to the floor with fixings suitable
to the materials of construction of the floor. 13mm diameter holes are provided adjacent to the
levelling bolts to allow the unit to be fixed to the floor. Depending on the generator model you will
have 4 or 8 fixing positions. Typically 10mm or 3/8” floor fixings approx. 75mm or 3” in length will
be suitable on most concrete floors.

Page 15

Operation Manual Nitropac N01x – N06x
Generator Environment
The Generator is designed for indoor use only. It should be installed adjacent to the
application it is supplying. If this is not convenient then the unit can be sited
elsewhere, however, consideration should be made of the lengths of pipe runs as
pressure drops can result from extended runs of pipe.
Consideration should be given to the location of the generator to ensure it is
protected from extreme fluctuations in ambient temperature. Ensure that adequate
ventilation is provided for the surrounding area, (depending on the operating
specification and model selected the generator can produce up to a maximum flow
of 2,556 L/min). Installation in a confined space or poorly ventilated space is not
recommended, however if you choose to do so ambient oxygen monitoring
equipment is recommended.
Please refer to the drawing below for the general dimensions of the unit.

Compressed Air Quality
The Nitropac Generator is an air purification system; it does not generate any gas pressure. Gas
pressure is created and supplied to the generator by the user’s compressed air system. It is the
user / installer’s responsibility to ensure that all components connected to the gas
generator comply with local health and safety regulations and that the compressed
air system is suitably protected from over pressure, including appropriately sized
safety relief devices for both the compressed air and nitrogen process tanks.

No pressure greater than 10 barg should be applied to the inlet of the Nitropac product.
The Nitropac Generator will typically be the last stage in a complete air compression and filtration
system, the inlet air quality must meet a minimum of IS0 8573-1:2010 class 2.2.1. Class 2.2.1. is
further defined as:
Class 2 – Particulate
Per cubic meter of air the particulate count should not exceed 400,000 particles in the 0.1 to 0.5
micron range, 6000 particles in the 0.5 to 1 micron range and 100 particles in the 1 to 5 micron
range.
Class 2 – Water
A minimum pressure dewpoint (PDP) of -40odegC (-40odegF) is required, no liquid water is
permitted.
Class 1 – Oil
Per cubic meter of air the maximum permissible oil content is 0.01mg, total level for liquid,
aerosol and vapor.

Recommended Piping Layout
To allow proper operation and commissioning of the generator it is important to include bypass
valves at the generator inlet / nitrogen outlet of the system. It is also recommended that a Nonreturn valve be fitted on the exit of the system to prevent downstream pressure from returning to
the system and damaging the generator. Please see below for recommended piping layout.

Page 19

Operation Manual Nitropac N01x – N06x

Commissioning / Safe Start-Up Procedure
With reference to the diagram above in “Recommended Piping Layout” section.
Once the generator has been installed, DO NOT Switch on the power immediately. It is
recommended that the inlet compressed air supply valve (1) remains closed, and that the inlet
bypass valve (2) is opened slightly to sufficiently allow the inlet compressed air to vent and purge
any remaining moisture from the newly installed pipework (if this is the first operation of the
compressed air supply, it is recommended that the air be vented for a minimum of 2hrs to allow
the air filtration and dryer to stabilise). Once the inlet pipework has been purged, the inlet bypass
valve (2) can then be closed and the pressure gradually introduced to the generator by slowly
opening the compressed air inlet (1) valve. The outlet bypass valve (3) should now be open to
atmosphere, and the delivery valve (4) to the customer application should be closed. Ensure that
both Process Tank Isolation valves (5) are both fully open. The power can then be turned on. On
first start up air will be introduced to Column 1 and the front panel gauge will slowly start to rise.
The front panel display will show a message “COLUMN 1” and a timer counting up. After approx.
30 to 80 seconds (timing will vary depending on your specific performance requirements) the front
panel display will briefly show an “EQUALIZING” message and the pressure on Column 1 and 2
gauges should level out. Column1 will then vent rapidly to zero and column 2 will continue to rise
slowly. During this process the TANK pressure gauge should continue to slowly rise. Allow the
Nitrogen Process Gas Tank to reach pressure, then continue to vent the outlet gas through the
bypass valve (3) for a minimum of 4 hours (ideally this should be done overnight to fully purge all
the remaining oxygen/moisture in the system). The Generator has been pre-set in the factory to
give the specified output flow-rate and pressure. Failure to achieve the factory specification after
maintenance may be as a result of an incorrect service procedure, please review any
maintenance carried out. If unable to achieve specification contact Donaldson for further
assistance. After this time the outlet bypass valve (3) can be closed, and the delivery valve (4) to
the customer application should be slowly opened to pressurise the line.

Page 20

Operation Manual Nitropac N01x – N06x
The design of the generator is that it will deliver up to your specific output pressure and flow of
Nitrogen. Should the demand for Nitrogen be less than the rated output flow, or indeed should the
demand stop the generator will automatically go into ECO Mode and the front panel LED will
illuminate. In ECO mode the changeover of the columns is suspended which will stop the
consumption of inlet compressed air. The control system will automatically detect when the
demand for Nitrogen resumes and the generator will start to produce Nitrogen again.

Page 21

Operation Manual Nitropac N01x – N06x

Normal Operation
The Nitropac Gas Generator is designed specifically to minimize operator involvement. Given that
the system is installed as described in earlier sections and is serviced in accordance with the
specified maintenance recommendations (see Service Requirements), then it should simply be a
matter of turning the Generator on. Note: the generator will only produce Nitrogen on demand. It
should typically be left in a powered state, with compressed air supply live. If the system is
shutdown, or suffers a power failure, it will restart automatically. However, if left without inlet air
pressure for a prolonged period and the Nitrogen Process tank is allowed to vent all pressure,
then the commissioning process above should be repeated to purge the oxygen from the system
before good quality gas can be produced again.
The Generator will automatically produce the factory set flow and pressure.
Note: The side panels of the generator should not be removed during operation
unless you have received training and are technically competent to manage the
potential risks present. Located inside the cabinet are the Vent silencers and
Safety Relief valve, these will periodically release gas at pressure, and could
cause injury.

On the rear and top of the generator are located inspection plugs. These plugs
must NOT be removed whilst the system is under pressure. If removed, it is likely
that pressure will be released, violently and cause injury.

Cleaning
Clean the outside of the Generator only using warm soapy water and a clean damp cloth. Ensure
the cloth is thoroughly rung out to remove excess fluid prior to use. Do not use decontamination
or cleaning agents that could cause a HAZARD as a result of a reaction with parts of the
Generator or material contained within it. If there is any doubt about the compatibility of
decontamination or cleaning agents please contact your Donaldson representative.
Cleaning should only be undertaken with the power switched off and the
power cord removed from the Generator.

Under no circumstances should any solvents or abrasive cleaning
solutions be used as these can contain fumes that could be harmful to the
Generator.

Care should be taken with Leak Detections Liquids.

Page 22

Operation Manual Nitropac N01x – N06x

Service Requirements
Servicing and/or repair of the Generator should only be undertaken by a
TECHNICALLY COMPETENT PERSON with the Generator in a safely
isolated condition.

Safe Isolation Process
To shut the system down, close the inlet air supply valve (1), BUT leave the electrical power on to
the generator. Close the Nitrogen outlet valve (4) to the application, and slowly open the bypass /
commissioning valve (3) to allow the Nitrogen product gas to vent to atmosphere. NOTE: do not
isolate the Process Tank valves (5) as this will trap pressure in the tank. For the product to be
completely safe to work on ALL pressure must be fully dissipated. Ensure ALL front panel gauges
read zero before turning off the power on the front panel and removing the mains cord from the
left hand side of the generator before proceeding. Note: Due to the nature of the Carbon Sieve it
could take considerable time for the generator to release all the trapped oxygen. The bypass
valve (3) should remain open at all times, as the CMS can release oxygen and pressure can build
again if closed.
Once service operations have been completed the generator can be re-connected to the mains
supply and the Commissioning process described in earlier sections should be repeated.
Due to the simplicity of the design and the small number of moving parts the Industrial Nitropac
Series Nitrogen Generators will have a long and trouble free life. However as with all technical
equipment it should be regularly inspected and serviced as below.
