DescriptionThis manual describes the installation and use of the Nordson Corporationnitrogen generation system. When necessary, the reader is referred to thedocumentation supplied with other Nordson products or products suppliedby third parties.

The nitrogen generation system produces nitrogen gas from compressed air.The system may be used with any foam system or added to any applicationthat requires a nitrogen blanket. The system includes the nitrogen generator.An optional booster capable of boosting lower pressure nitrogen to arequired pressure is also available.

Figure 1 Nitrogen generator system

1. Nitrogen generator 2. Optional booster



Theory of OperationThe generator is self-contained and consists of the following maincomponents:S a dual-stage filtering sectionS a nitrogen membrane assemblyS a precision orificeS an output accumulator

The dual stage filter removes unwanted debris, moisture, and trace oil vaporfrom the supply air. Both filter stages are equipped with high capacity floatdrains for automatic moisture removal, a pressure relief valve, and aone-quarter turn bayonet bowl closure for easy filter element replacementwithout the need for tools. The first stage filter also has a differential pressureindicator to signal filter changes.

The nitrogen membrane separates the incoming supply air, allowing nitrogengas to pass through while filtering out unwanted gasses. This results in acontinuous flow of a dry nitrogen gas supply at a purity level of95-99.5 percent.

The precision orifice controls the flow rate of gas through the generator tomaintain purity. The maximum flow rate for this combination is approximately137 l/hr.

The output accumulator helps stabilize the pressure of the nitrogen gasoutput for varying gas flow rates.

The nitrogen generation system may be operated independently to producenitrogen to a pressure of up to 7 bar (100 psi). An optional booster isavailable for higher pressure requirements. The booster is capable ofboosting pressures up to 138 bar (2,000 psi).

Install Pressure Gauges As NeededInstall pressure gauges as desired so that full system depressurization canbe verified prior to service activities.

Perform Initial Startup1. Turn on the air supply to the nitrogen generator.2. Verify that gas is being delivered from the NITROGEN OUT port on the

generator.3. If the optional booster was installed:

a. Turn on the air supply to the booster.b. Place the booster PUMP RUN switch in the ON position.c. Adjust the booster air regulator. If the booster pump strokes and the

booster pressure gauge responds, then the booster is operatingproperly.

4. Verify that the nitrogen gas blanket is operating properly on the receivingequipment.

The system is ready for routine operation.

OperationBefore operating the system for the first time, ensure that you havecompleted the procedures under Installation.

Daily Startup and Monitoring1. Turn on the air supply to the nitrogen generator and, if used, the booster.2. If applicable, place the booster PUMP RUN switch in the ON position.3. Verify that the correct system pressures have been obtained. Make

adjustments as needed.4. Ensure that automatic drains and filters are functioning properly.

CAUTION! Risk of equipment damage. Do not operate the nitrogengeneration system if the FILTER STATUS indicator needle is in theCHANGE area. Doing so may damage the nitrogen membrane.

5. Check the FILTER STATUS indicator. If the needle is in the CHANGEarea, replace the nitrogen filter elements. Refer to Filter ElementReplacement underMaintenance.

Daily Shutdown1. If desired, reduce or turn off the air supply and relieve system pressure.

Refer to System Pressure Relief underMaintenance as needed.2. If applicable, place the booster PUMP RUN switch in the OFF position.



MaintenanceThis section contains a recommended maintenance schedule andprocedures. Attempting any other maintenance procedures can result inequipment damage, improper system operation, or personal injury.

Recommended Maintenance ScheduleTable 3 provides recommended maintenance activities and a schedule forperforming those activities. Base how often you perform maintenance onyour operating conditions.

Table 3 Recommended MaintenanceActivity Interval Procedure

Inspect forexternal damage

Daily When damaged parts pose a risk to the operationalsafety of the unit and/or safety of personnel, switch off thesystem and have the damaged parts replaced byqualified personnel. Use only original Nordson spareparts.

Clean the exterior Daily Remove dust, flakes, etc. with a vacuum cleaner or a softcloth.

System Pressure ReliefSystem pressure must be relieved before you can safely proceed with manytroubleshooting and service-related activities for equipment used with thenitrogen generation system. Follow this procedure whenever you need torelieve system pressure.

CAUTION! Risk of pressure buildup. The nitrogen generation system ispressurized when operating. Depresserization may take some time after theair supply is shut off. Before servicing any equipment used with the nitrogengeneration system, ensure that the system is fully depressurized.

NOTE: Always depressurize the generator before depressurizing thebooster, if present.1. Shut off the main air supply or set the air pressure regulator to zero (0).2. If the booster is present:

a. Loosen the GAS OUT hose fitting and allow the nitrogen pressure tobleed off.

b. Ensure that the booster pressure gauge reads zero (0).c. Tighten the fitting.

3. When the service activity is completed, restore the system to normaloperation.



Filter Element ReplacementThe nitrogen filter elements should be replaced when either of the followingconditions occurs:S the FILTER STATUS needle indicates CHANGES every six months (even if the FILTER STATUS needle does not

indicate CHANGE)Always replace both filter elements. Refer to Parts for the filter element kitpart numbers.1. Relieve system pressure. Refer to System Pressure Relief earlier in this

section as needed.2. See Figure 6. Remove the filter housings by turning them ¼-turn

counterclockwise.NOTE: It is not necessary to remove the cover for this procedure.

Figure 6 Removing the filter elements (generator shown with cover removed)



3. Grasp the filter element and pull it straight down to remove it from thehousing.

4. Install new filter elements in the housings.5. See Figure 7. Install the housings, turning them ¼-turn clockwise to

secure them. Ensure that the stage 1 and stage 2 filters are installed inthe correct order, as shown in Figure 7.

6. Restore the system to normal operation.

TroubleshootingThis section covers only the most common problems you may encounter. Ifyou cannot solve a problem with the information given here, contact yourlocal Nordson representative for help.

For additional troubleshooting information, refer to the manuals provided withthe other equipment used in the system.

Nitrogen Generator Troubleshooting

Problem Possible Cause Corrective Action1. Low air supply

pressureInlet air pressure too low Ensure that the air supply pressure is

greater than 4 bar (60 psi).Check for leaks.

2. Low nitrogen supplypressure

Obstructed filter(s) Check for obstructed filters. Replacethe filter elements or filter assembliesas needed. Refer to Filter ElementReplacement underMaintenance asneeded.

Low air supply pressure Ensure that the air supply pressure isgreater than 4 bar (60 psi).Check for leaks.

Blocked orifice Clean or replace the orifice.Obstructed nitrogen membraneassembly

Replace the assembly.



Booster Troubleshooting

Problem Possible Cause Corrective Action1. Pump will not cycle

(only regulatednitrogen pressure atoutput)

No air supply to pump Check the air supply and resolveissues.

Pump regulator set too low Increase the setting.2. Pump will still not

cycle (only regulatednitrogen pressure atoutput)

Four way air reciprocating valvespool stuck at mid-position

Disconnect and then reconnect theair supply (this will reset the air spoolto the end position).If the spool still sticks, manually pushthe spool to the far end by inserting aprobe through the hole in the spoolstop cap. If the spool is stuck orrequires excessive force,disassemble the air valve assembly.Inspect for contamination ormechanical bind. Repair or replace asneeded, lubricating the seals withwaterproof grease.

3. Pump makes onecycle, then stops

Faulty 2-way air valve (broken,leaks, or contaminated)

Repair or replace.

4. Pump cyclesconstantly whendead-headed

External leak at pump or indownstream high pressure circuit

Check for leaks and resolve issues.

Check valve cartridgecontaminated or stuck open

Clean or replace.

Internal leak in pump Check all dynamic and static sealsand gaskets and replace as needed.
