2. General safety
For your own safety, when carrying out work on this product, all relevant national safety
regulations must be complied with relating to pressurized and electrical systems.
Intended use of the Product
The generator is exclusively intended for the production of N2 from compressed air, which is free from bulk
water, oil and solid matter constituents.
The product should be sited within a building and protected (see section 7.1 Site selection). The generator
must be operated only in accordance with the data on the rating label and in accordance with the contractual
conditions. Any operations that do not comply with those stated on the product rating label will render the
warranty void.
This product is only designed to operate at pressures of between 87 - 145 psig (6 - 10 barg).
It is not suitable for pressures in excess of 145 psig (10 barg).
No modifications must be made to the product. Any modifications may reduce the operational safety of the
product and invalidate the manufacturer’s warranty, potentially resulting in damage to the product and serious
personal injury.
Personnel
Only authorized, competent and trained personnel are permitted to work on the product. This user guide is
intended solely for such personnel and is to be used only as a reference; it should not be used to replace
conventional training.
Safe handling
Please ensure the relevant safe engineering practices and handling procedures are employed when handling,
installing and operating the product. Ensure that the equipment is depressurized and electrically isolated, prior
to carrying out any of the scheduled maintenance instructions specified within this user guide.
A suitable lifting aid must be used to minimize the risk of physical injury or damage to the
product.
IMPORTANT: It is essential that the system into which the product is in-
stalled is fitted with a pressure limiting/relief device. This device should
be between the compressor and the generator. The device must be set to
prevent the maximum working pressure of 145 psig (10 barg) from being
exceeded.

Inlet pressure dewpoint required is ISO8573.1 Class 5 for water 45°F (+7°C)
3 stage inlet filtration is required , e.g. Water separator and 2 high efficiency coalescer filters (see system
layout on page 11) to protect the generator from bulk water, particulate and oil aerosol.
3. Description of Product
3.1 Technical Specification
The n-psi 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, filled 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 flows 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 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 separation and regeneration modes to ensure continuous and uninterrupted
nitrogen production.
When a generator is specified with an internal dryer, each CMS column has a unique adsorbtion media tube
(AMT) technology dryer fitted into the bottom of each column.
The unique AMT dryer does not require servicing and the life is aligned to the CMS material.
The internal AMT dryer reduces energy running costs by elminating the additional external dryer purge (typically
20-25% of the dryer inlet air consumption) and the associated pressure loss across an external dryer. The
compressed air supply is also reduced accordingly.
The oxygen concentration in the nitrogen stream is monitored continuously on models fitted with an oxygen
analyser. 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.
Parameter Units

2. Documentation
• 1 x User Guide
• 1 x Declaration of Conformity
3. Packaging
• 1 x Generator support base and box cover
• Care Should be taken and inspection undertaken during unpacking to ensure that the product is
not damaged.
• Verify that all component parts have been supplied with the generator

Page 717-110-0142
4.1 Packaging
All products are securely packaged in a bespoke wooden packing box. The generator will be held in a
horizontal position by wooden struts; using straps to secure the product to the box base. The box top cover
can be removed by removing the 4 fixing screws and lifting off in one piece.
The support packing box permits longitudinal stacking; however the central section of the packing
box should not be considered load bearing.
Damage to the packaging
• Check immediately to establish whether damage has occurred to the external packaging and if the
damage extends to the product inside.
• If there is damage to a product, contact the relevant supplier immediately.
In no circumstances must a damaged product be used in operation. Using damaged
products can lead to irreparable functional faults or cause serious physical harm.

4.2 Unpacking the Equipment
The generator is supplied in a wooden crate. It is recommended that the crate be moved into position using a
forklift truck or pallet truck. Remove the generator from the wooden crate using an overhead crane. Use the
following illustrations for correct guidance on safe handling and lifting techniques.
