3. Product Description
3.1 Technical Specication
The nitrogen generator operates on the Pressure Swing Adsorption (PSA) principle to produce a continuous
stream of nitrogen gas from clean dry compressed air.
Pairsofdualchamberextrudedaluminiumcolumns,lledwithCarbonMolecularSieve(CMS),arejoinedvia
an upper and lower manifold to produce a two bed system. Compressed air enters the bottom of the ‘online’
bedandowsupthroughtheCMS.OxygenispreferentiallyadsorbedbytheCMS,allowingnitrogentopass
through.
After a pre-set time the control system automatically switches the bed to equalization mode where the online
bed pressure is equalized with the second regenerated bed. Once equalized the online bed is switched to
regenerativemodeandoxygenisventedfromtheCMS.Asmallportionoftheoutletnitrogengasisexpanded
into the bed to accelerate the regeneration. At the same instant the second bed comes on-line and takes over
the separation process.
The CMS beds alternate between online equalization and regeneration modes to ensure continuous and
uninterrupted nitrogen production.
Whenageneratorisspeciedwithaninternaldryer,eachCMScolumnhasauniqueadsorptionmediatube
technologydryerttedintothebottomofeachcolumn.
The unique intergrated dryer does not require servicing and the life is aligned to the CMS material.
Theintergrateddryerreducesenergyrunningcostsbyeliminatingtheadditionalexternaldryerpurge(typically
20% of the dryer inlet air consumption) and the associated pressure loss across an external dryer. The
compressed air requirement is also reduced accordingly.
Theoxygen concentrationin thenitrogen streamis monitoredcontinuously onmodels ttedwith anoxygen
analyzer.Iftheoutletconcentrationexceedstherequiredproductionlevel,thenitrogenoutletisclosedandthe
gas is vented to atmosphere. Normal operation will resume when the purity recovers.

• When the connection is made you can start the generator using the HMI screen, the generator will
operate normally. If the connection is broken, i.e. the generator has been remotely switched off, the
generator will commence shut down procedure, stop cycling and go into standby mode this can also be
achieved by using the shutdown feature on the HMI screen, displaying “STANDBY” on the display once
completed.
• Using remote stop / start ensures the correct shut-down sequence is implemented.
8.3 Start Up Procedure
• Ensure that all isolation valves are fully closed before operating.
• Hold down the Start/stop button located on the HMI Screen, this will start the generator.
• Slowly open the air inlet valve (page 11/12) and check for any leaks. Continue to open the air inlet valve
until fully open.
• Allow the generator to cycle at least two times.
• Slowly open the ‘To buffer tank’ isolation valve (page 10/11) until the buffer tank is at full pressure
(this will take a few cycles)
• Slowly open the ‘From buffer tank’ isolation valve (page 10/11). At this point the generator control system
will be able to operate fully.
Beware, it can take up to two hours to clean the buffer tank.

10. Maintenance
Maintenance operations should only be carried out by authorized, competent and
suitably trained personnel.
• Maintenance operations only to be conducted when the system has been shut down, fully depressurized
and isolated completely from the compressed gas and electrical supply.
• Ensure the system is in a safe condition for maintenance to be carried out.
• Dismantle and assemble with care, paying particular attention to the areas that become pressurized.
• Replace with new seals, all gaskets removed during maintenace operations.
• Do not modify or adjust the control settings.
• Onlycertiedandapprovedreplacementpartsfromthemanufactureraretobeused.
• Always check all connections / sealing faces for cleanliness and secure seating prior to assembly.
• Ensureallcomponentsarerettedtotheproductbeforeoperation.
• Gradually build up pressure in the generator and check for any leaks.
• Ensure the generator is left operating in a safe working condition after completion of maintenance.
10.1 Daily checks
Visual and functional check of the generator should be carried out daily.
• Checkthegeneratorforcorrectoperation,anyexternaldamageandleaks.
If defects found, immediately depressurize and isolate product until defects are rectied.
• If the service required display appears on the screen or the alarm signal activates, the generator must be
serviced.
Contact your supplier and request a product service kit.
• Remove any loose dust or dirt from the product , clean with a damp cloth only, all surfaces that appear to
have attracted unwanted contaminants.
• Ensurethegeneratorisoperatingwithinthepurityspecication,parameters,pressure,temperatureand
owrate.
10.2 Cleaning
Cleantheequipmentwithadampclothonlyandavoidexcessivemoisturearoundanyelectricalsockets.
If required you may use a mild detergent, however do not use abrasives or solvents as they may damage/
degrade the warning labels on the equipment.
Beware a characteristic of the CMS could cause the vessel to repressurize slowly up to
2 barg.
