NITROGEN
Nitrogen is more than an inert gas. It's an operational tool.
Most operations use nitrogen without fully leveraging it. Here’s why high-pressure nitrogen is critical across Africa’s key industries, and what happens when the supply isn’t right.
NITROGEN IS 78% OF THE AIR WE BREATHE - BUT INDUSTRIAL NITROGEN IS A DIFFERENT ANIMAL
Industrial high-purity nitrogen (99.5%–9.999%) is used precisely because it is inert - it won't react, won't combust, and won't contaminate. The purity level and pressure determine everything about how it performs in your process.
THE RISK OF UNDERSIZED OR IMPURE NITROGEN SUPPLY
Using compressed air instead of nitrogen for inerting or blanketing introduces oxygen - creating explosion risk in refineries and corrosion in pipelines. Using low-pressure nitrogen for pipeline testing results in inaccurate results and potential rework costs.
ON-SITE GENERATION VS CYLINDER SUPPLY: WHICH IS RIGHT FOR YOUR OPERATION?
Cylinder supply works for intermittent use. For continuous operations - refineries, large-scale food processing, mining - on-site nitrogen generation via a Denair PSA or membrane unit delivers lower long-term cost and eliminates supply chain risk.
WHEN YOUR CYLINDER PRESSURE ISN'T ENOUGH: NITROGEN BOOSTING
Standard cylinders deliver nitrogen at up to 200–300 bar. Many applications - pipeline testing, hyperbaric environments, high-pressure process systems - require 500–1,000 bar or more. A Maximator nitrogen booster bridges that gap without a new generation system.

Frequently asked questions
What's the difference between a nitrogen generator and a nitrogen booster?
A nitrogen generator produces nitrogen on-site from compressed air using PSA or membrane technology. This is ideal for continuous, high-volume use. A nitrogen booster takes nitrogen already in a cylinder and increases its pressure to meet your process
requirement. Many operations use both: a generator for volume and a booster for high-pressure applications.
