Nitrogen Purging with a Nitrogen Generator

Nitrogen gas is often used for purging, a process that is utilized in a wide range of industries - from Gas & Oil to Winemaking and Food Packaging.

Nitrogen gas is a clean, dry, inert gas that makes up 79% of the air we breathe.  A Nitrogen Generator effectively separates and isolates the N2 molecules from the air, allowing it to be applied to an atmosphere that requires little to no oxygen for safety or preservation purposes.


Nitrogen Purging Can Eliminate Oxygen

In certain situations, Oxygen can be a highly dangerous presence, providing a vital element for combustion or corrosion.  In order to displace Oxygen and eliminate these threats, a high volume of Nitrogen gas is pumped into an atmosphere, vessel or closed system of piping with a continuous, uninterrupted flow.

Situations where combustion is a threat include aircraft fuel tanks, chemical processing, and oil and gas wells.

Situations where corrosion is a threat include a power plant boiler, HRSG layup, and fire protection systems.

Nitrogen Purging for Safety and Quality

Nitrogen purging affects not only the safety of an atmosphere, but also the quality of the overall system or final product.  As mentioned earlier, N2 gas is applied to scenarios where combustion or corrosion can undermine the safety and performance of a system or process.

But Nitrogen purging is also used to ensure the quality of a product, as in Modified Atmosphere Packaging (MAP) used with food packaging.  MAP is used to minimize the Oxygen within packaging to prevent spoilage and preserve properties such as aroma, flavor and texture of the packaged foods.

Nitrogen purging is also used with Medical Device Packaging to maintain sterility, freshness, and shelf life in an effort to preserve cleanliness and get the most accurate test results possible.

Economical and Effective N2 Purging with a Nitrogen Generator

Since N2 purging requires a continuous and uninterrupted flow of N2 gas, a Nitrogen Generator is the most economical and effective source of N2 available.  Where high pressure N2 cylinders need to be switched out with stored extras to maintain a flow - always with the threat of running out during peak use - a Nitrogen Generator supplies a steady source of high purity N2 gas on-demand at any given time.
