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.
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.

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 o 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.
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.
Rawl Bolt Installation
1. Drill a hole of required diameter and depth.
2. Remove debris and thoroughly clean hole with brush and pump.
3. Insert anchor through fixture into hole and tap until required installation depth is
achieved.
4. Tighten to the recommended torque.

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.
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.
