Nitrogen Generation

Nitrogen is commonly used in industry because it is dry and inert. While traditionally nitrogen has been obtained through liquid N2 deliveries and high pressure compressed gas cylinders, onsite nitrogen generation is a more modern approach that places you in control.

Nitrogen generators continuously produce high purity nitrogen from compressed air and the installation is simple: pipe in compressed air and pipe out nitrogen.

Just connect a compressed air line to the inlet of the nitrogen generator package, connect the outlet to your nitrogen line and the unit is ready for trouble free operation.

A continuous supply of consistent purity is then available minutes after start-up, and it can expand in line with your business needs – a complete future proof solution!

Benefits of onsite Nitrogen Generation

Supply on demand

Nitrogen generators are designed to operate to meet your demand, up to 24 hours/day, 7 days/week. Having a constant and reliable supply of nitrogen removes the inconvenience of running out of stored nitrogen or waiting for deliveries during adverse weather conditions. And by matching the demand, it reduces potential downtime of equipment.

Low operating costs

The cost of generating your own nitrogen is typically 20%-30% less when compared to bottled nitrogen or bulk liquid nitrogen storage. Generating your own nitrogen also eliminates ongoing costs for having gas delivered as well as in house re-ordering processes.

Environmental responsibility

Using a nitrogen blanket during beverage storage, pre and post bottling, prevents the growth of bacteria and other microbes. Another use is purging air from pipes and hoses prior to bottling and to ensure oxygen is not introduced during transport. It can also help to preserve taste and freshness.

Improved safety

Nitrogen generators remove the health and safety concerns regarding high pressure storage cylinders or cryogenic vessels, along with no more potential hazards associated with trucks entering site to load/unload high pressure liquid nitrogen.

Nitrogen purity

Able to provide purity levels up to 99.999%, modular nitrogen generator units have continuous real time monitoring inbuilt, so you can see the purity produced at any time.

Direct Air are experienced in providing Nitrogen generation equipment for many industrial applications. Here are a few examples:

Food packaging

Residual oxygen within a package promotes bacterial growth and oxidation, which can compromise quality and shelf life. Using nitrogen minimises the levels of oxygen present, therefore preserving quality and improving shelf lie. This is particularly relevant to coffee processing, meat packaging, dried foods processing and lettuce packaging.

Beverage applications

Using a nitrogen blanket during beverage storage, pre and post bottling, prevents the growth of bacteria and other microbes. Another use is purging air from pipes and hoses prior to bottling and to ensure oxygen is not introduced during transport. It can also help to preserve taste and freshness.

Chemical processing

Blanketing with an inert gas, such as nitrogen, is often used to ensure the chemical integrity and maximise safety. Nitrogen tank blanketing controls the oxygen concentration and humidity within the vessel, protecting the product from contamination, degradation, and chemical change. The reduced oxygen level minimises the chance of explosion. A nitrogen blanket can also be used to balance tank volumes and prevent collapse during unloading.

Metal processing

The use of nitrogen is widespread in the metal processing industry, including much of the support equipment such as lasers. Using nitrogen to minimise the contact with oxygen improves final product quality and minimises rework.

Electronic applications

Nitrogen is mainly used for automatic soldering machines and stops the oxidisation of solder.
