Technical Description
Basic Concept
The i-Flow N2 Select is an all-in-one Nitrogen gas generation solution. It consists of an
air dryer, filtration, carbon tower, nitrogen generator & process tank, all conveniently
assembled on a plug & play skid plate. The system requires an inlet feed of compressed
air supply to operate, which is passed through a refrigerant dryer & carbon tower, with
pre-& post filtration at multiple stages before entering the i-Flow nitrogen generator.
The generated nitrogen is then fed to a process tank, before returning back through
the generator for a final quality/purity check, before passing downstream to the
application. Should the demand for nitrogen be less than the rated output flow, or
indeed should the demand stop, the generator will go into ‘Standby’ mode. At this point
the gas generation system will stop producing nitrogen. Once demand resumes & the
process tank pressure goes below a certain level, the generation system will resume
normal operation and begin to produce nitrogen gas again.

Installation
System Environment
The i-Flow N2 Select skidded system is movable by forklift using the 2
upper slots on the long edge shown below.
CAUTION

Figure 1

Figure 2
Care must be taken when lifting due to the un-even weight distribution of the individual
component parts. The forklift slots are 800mm (long edge) apart, and as such will require
a forklift with the appropriate fork span and lifting capacity. The lower slots on the short
edge are only intended to adjust the final position of the skid (i.e. shuffling the skid into
exact position once lowered from the forklift) and are not to be used for full lifting of
the skid. Ensure appropriate power supply and compressed air supply are available at
installation location.

Page 16

The system is designed for indoor use only but can also be housed in a suitable,
weatherproof enclosure, provided the environmental parameters meet operational
specifications detailed in this manual. The system should always be positioned in such a
way that it can be easily switched off and commissioning valves can be accessed easily.
Ensure a gap of at least 500mm is allowed around the skid system to
allow for air flow and accessibility.
WARNING

System Positioning
Once in place, we recommend that the skid system is be bolted in place using the 8mm
thick L-brackets which have 16mm pre-drilled holes in them & we recommend using
M12 securing bolts. Always ensure that the system is installed by a Peak approved &
qualified technician.

Electrical Connection
Connect the system to an appropriate 230-volt single-phase supply. Ensure appropriate
circuit breakers (2 amp – C-Curve for both the i-Flow and refrigerant dryer/ filtration)
are used at the distribution panel to serve as a disconnect device. The disconnect device
must be clearly marked, easily accessible and as close to the system as possible. Refer
to the system serial plate for input specification and ensure your supply matches the
requirements.
Ensure that mains supply cable has an adequate rating (3 core, 1.5mm2, H05VV-F, 500v).
Failure to do so could cause damage to the system.

WARNING

This unit is classified as SAFETY CLASS 1. THIS UNIT MUST BE
EARTHED. Before connecting the unit to the mains supply, please
check the information on the serial plate. The mains supply must be of
the stated AC voltage and frequency.

Commissioning & Safe Start-Up Sequence
This procedure must be followed to ensure the nitrogen generation system is operating
correctly and in a safe state. It is mandatory that this procedure be followed after any
service operation has been carried out.
All servicing and repair must be carried out by Peak Gas Generation or an authorised
Peak partner.
After servicing and restart of the system, the tanks should build pressure to the factory
set value (visible on external pressure gauges) and the i-Flow and Air Dryer should
initialise as per their respective user manuals, showing no errors or warnings.
NOTE: Where the below instructions make reference to the i-Flow Nitrogen Generator
or the Refrigerant Dryer, please refer to the individual User Manual documents
(separate, but included with system) provided.
With reference to Pneumatic diagram (Figure 7):
1. Once the Generator has been installed, ensure all valves (1-7) are shut, DO NOT Switch on
the power to the i-Flow Generator immediately. First Switch on the Air Dryer (note: this
includes power to all Air Filtration equipment). Remove the blank plug from and open valve
2. Partially & slowly open the Air supply valve (1), to allow the inlet compressed air to vent &
purge any remaining moisture from the newly installed pipework & equipment.
3. After 5-10 minutes shut valve (2) replacing the blank plug and slowly fully open valve (1).
This will introduce the compressed air supply up to the i-Flow Generator inlet. At this point
valve (1) should be open and valves (2-7) should all be in the closed position. The Inlet
pressure will be indicated on the Carbon Tower gauge.
4. Open Valves (3) & (4) to put the N2 Process Tank online to the i-Flow Generator.
5. The power to the i-Flow generator can now 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 have an orange background and show a message “BYPASS ACTIVE” “HIGH
OXYGEN”. During this period, the i-Flow Generator will begin to cycle and will automatically
vent poor quality gas internally through the built in Bypass feature. Normal cycle is as
follows: Column 1 gauge will start to rise in pressure, after approx. 40 seconds the Columns
will briefly “EQUALIZE” 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.
6. Allow the N2 Process Tank to reach pressure and stabilise (timing will vary depending on
the starting contents of the process tank). From first start-up with air in the tank, it is likely
to take 8 to 10 hours to purge the oxygen to an acceptable level. The actual oxygen content
(in parts per million) is displayed on the front panel screen. Once the oxygen content drops
below the required level, the system will automatically exit BYPASS mode.. The front panel
screen will remain with an orange background for 24hrs from first power on, and during this
time all pressure and purity alarms are disabled.

7. The Generator has been pre-set in the factory to give the specified output flowrate and
pressure. Failure to achieve the factory specification after maintenance may be as a result of
an incorrect service procedure, so please review any maintenance carried out. If still unable
to achieve the specification, please contact Peak Gas Generation for further assistance.
8. Once the N2 Process Tank has stabilised and the generator has exited BYPASS mode, then
remove the blank plug from valve (5) and open valve (5), with valve (6) remaining closed
for a period of 5 to 10 minutes to purge the line.
9. Once the line has been purged, close valve (5) and replace the blank plug. The System is
now ready for use and valve (5) can be opened to the application.
The System is now ready for use.
Once installed and commissioned, as described above the design of the gas generator
is that it will deliver up to your specific output pressure and flowrate 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 ‘Standby Mode’ and the
front panel LED will illuminate. In Standby 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 gas again. DO NOT turn off the power to the i-Flow or the Air Dryer
without following the Shutdown procedure detailed below. Normal operation is to leave
the i-Flow and Dryer with Power ON and compressed Air Supply ON.

Connecting to the application
Once the initial purge run of approximately 8 hours has completed (required to reach
purity for the application), it is ready to be connected to the application(s).
