i-Flow is the culmination of Peak Gas Generation’s
innovations and technological expertise. It builds upon
over two decades of experience as industry leading gas
generation specialists. Designed & engineered in the UK
by an ISO 9001 accredited manufacturer, i-Flow utilizes
the latest Pressure Swing Adsorption (PSA) technologies,
optimized for maximum energy efficiency, with over 100
preconfigured flow rate (1.3 - 255 m3/hr) and purity (up to
Our expert consultants design systems around business
needs, ensuring supply meets company demands
effectively and allows for expansion through the addition
of Peak CMS banks or generator modules, in order to
meet future business growth.
i-Flow offers the total solution, eliminating the need for bulk nitrogen gas
purchase, providing sustainable on-site nitrogen generation that allows
companies to control costs, reduce their carbon footprint and enjoy
massive benefits in the long run.
Bulk Supply vs On-site Generation
Beyond the highly variable costs of industrial gas, supply methods such as
cylinders, dewars and bulk liquid storage also create numerous challenges
for businesses, as well as many additional and hidden costs, which ultimately
impact on the bottom line.
• Cylinder or dewar rental & supply delivery charges;
• Bulk liquid storage planning permission, installation, rental & upkeep;
• Multi-year purchase contract commitments, with long notice periods.
Logistics & safety
• Frequent hazardous truck deliveries to facility
• High pressure storage, with risk of explosive decompression or leaks
• Cylinders & dewars require heavy manual handling
Product losses & wastage
• Unpredictable supply timescales
• Bulk supply needs frequent switching & monitoring
• 10% gas returned to supplier & 20% lost to ‘off-gassing’
• Downtime = lost revenue.
Why buy bulk nitrogen gas when
you can make your own?

SERV ALES OF
Gas Out = N2
Based on the latest Pressure Swing Adsorption (PSA) and
Carbon Molecular Sieve (CMS) technologies, i-Flow is optimized
with the capacity to deliver a continuous supply of nitrogen
gas to applications, whilst maximizing its energy efficiency
AIR IN = N2 + 02
with an innovative ‘eco-mode’.
High purity nitrogen
Our CMS banks are packed using a ‘snowstorm’ filling technique, allowing for around 18% more carbon to be
compacted into the carbon bed. This ultimately prevents gas channeling and ensures i-Flow can deliver maximum
levels of nitrogen purity (up to 99.9995% or 5 ppm oxygen*). Furthermore, integrating i-Flow with our compressed
air pre-filtration system, PureAir, guarantees the highest quality output by cleaning air before it enters the generator.
*Over 100 flow-rate and purities available, depending on system design requirements and commissioned specifications.
i-Flow’s highly robust PSA system generates nitrogen
gas using simple principle methods. Compressed air is
fed into the dual pressure CMS vessels and undergoes a
cycle of compression & decompression, where oxygen is
adsorbed and nitrogen is passed downstream. This not
only delivers continuous nitrogen gas flow-rates on a large
scale (1.3 - 255 m3/hr*), it also guards against abrasive
breakdown, preventing gas supply contamination and
ensures a CMS lifespan of around 20 years.
*Over 100 flow-rate and purities available, depending on system
design requirements and commissioned specifications.
Adaptable, future-proof design
Peak Gas Generation’s nitrogen generation systems are designed to be a futureproof, space-saving and sustainable solution. To accommodate inevitable
future growth and your expanding business needs, i-Flow can be scaled out
retrospectively, with additional Peak CMS banks or modular units. This offers
companies the flexibility to incorporate a solution that can continually adapt
infrastructure in line with growth, rather than being constrained by an increasingly
expensive or fixed capacity nitrogen gas solution.
Multiple units can be synchronized to meet
demands based on application flow-rates and
purity requirements (more units = greater
flow-rates at specified purity).
95 - 99.9995% purity 1.3 - 255 m3/hr
Up to ten CMS column banks can be added
to each single i-Flow unit in less than a shift,
increasing nitrogen production capacity with

Nitrogen gas is naturally clean, dry, inert and non-conductive. It is the most commonly
used and cost effective solution to a whole host of industrial manufacturing and
processing challenges. Below are just some examples of industry applications where
Peak Gas Generation’s nitrogen generation solutions can help a company maximize
its efficiencies and product quality, as well as increase profitability.
Food packaging & storage
Oxidation of perishable foods impacts on product quality and suitability for
consumption. Nitrogen gas is used for modified atmosphere packaging
(MAP), form filling and inert food storage. These help extend shelf-life,
minimize the need for chemical preservatives, prevent packaging collapse
and increase reach of product distribution.
Wine making & production
Oxygen contamination during processing and storage of wine can lead
to spoiling and often manifests as a rancid, vinegary taste, ultimately
impacting on consumer experience, as well as the producer’s reputation.
Nitrogen gas is used at numerous stages throughout, such as sparging,
blanketing and purging, helping to maintain product quality.
Pharmaceuticals & biotechnology
Exposure to oxygen & moisture causes contamination, which can alter
product composition, potentially rendering them useless or even make
consumption harmful. Nitrogen gas is used throughout the manufacturing
process for blanketing, inerting processing chambers (e.g. during milling or
spray drying) and even to sterilize packaging prior to product filling.
Laser cutting & welding
Material exposure to moisture or oxygen can impact on the quality and
structural integrity of end products. Nitrogen gas is used as an assist,
purge and shielding gas, ultimately helping to ensure better quality cuts or
welds and prevent against product discoloration due to oxide formation.
Electronics assembly & dry-box storage
Oxygen contamination can impact on product quality and the efficiency of
reflow, selective & wave soldering processes, causing production defects,
such as bridging or insufficient wetting. Nitrogen gas helps create inert
atmospheres in assembly environments, ultimately increasing first-pass
yields by minimizing reworking requirements.
