Why Nitrogen Is the Go-To Gas for Fire Prevention and Safety Systems

When it comes to protecting lives and property, fire prevention systems need to be reliable, effective, and long-lasting. While water-based fire sprinkler systems are the most common line of defense, a growing number of facilities are turning to nitrogen generators for fire protection as a smarter, more dependable solution. But why nitrogen? Let’s explore why this inert gas has become the go-to choice for fire safety systems worldwide.

The Problem with Oxygen in Fire Sprinkler Systems

Fire sprinkler systems that rely solely on compressed air or oxygen face a serious challenge: corrosion. Oxygen inside piping reacts with the water present in fire sprinkler systems, causing rust and deterioration over time. This leads to leaks, blockages, and even total system failure—putting both people and property at risk.

This is where nitrogen comes in.

Why Nitrogen Is Ideal for Fire Protection

Nitrogen, which makes up about 78% of the air we breathe, is an inert gas—meaning it doesn’t support combustion or cause corrosion. By introducing nitrogen into fire sprinkler systems, facility managers can:

  • Reduce corrosion – Nitrogen eliminates oxygen, preventing rust from forming inside steel pipes.
  • Extend system life – Fire sprinkler systems last significantly longer when paired with a nitrogen generator for fire protection.
  • Prevent costly leaks – Fewer pipe failures mean fewer expensive repairs and replacements.
  • Enhance safety – A dependable system ensures sprinklers work exactly when they’re needed.

Nitrogen Generators for Fire Sprinkler Systems

A fire protection nitrogen generator delivers a continuous, on-site supply of high-purity nitrogen to fire sprinkler systems. Unlike compressed gas cylinders, which require constant refills and logistical challenges, an on-site generator produces nitrogen on demand.

With a nitrogen generator for fire sprinkler systems, you get:

  • Consistent purity levels that keep oxygen out of your piping.
  • A cost-effective, long-term solution with minimal maintenance.
  • Peace of mind knowing your fire protection system is always ready.

Applications Across Industries

Nitrogen-based fire prevention systems are increasingly used in:

  • Commercial buildings – Protecting critical infrastructure and office environments.

The Basics: How Nitrogen Generators Work

Nitrogen generators come in two types: pressure swing adsorption (PSA) nitrogen generators and membrane nitrogen generators. Both types of generators require a source of compressed air. When the compressed air enters the nitrogen generator, the nitrogen separates from other gases. These gases are expelled from the generator, while nitrogen comes out in a steady, continuous stream.

Compared to bulk or cylinder nitrogen delivery, on-site nitrogen generation is beneficial in many ways.

  • Eco-friendly: On-site nitrogen generation is environmentally friendly. Nitrogen generators use little energy and do not rely on fossil-fuel-dependent vehicles for periodic transportation.
  • Low-cost: Nitrogen generators cost little money to operate every month. After the initial up-front cost, nitrogen generators have a low cost.
  • Reliable: Nitrogen generators are far more reliable than cylinder delivery, which can be affected by supply chain disruptions. Businesses with nitrogen generators enjoy a continuous supply of nitrogen whenever needed.
  • Unlimited supply: Nitrogen generators produce an unlimited supply of nitrogen. This allows businesses to scale their production up or down as needed.

Why PSA Nitrogen Generators Are the Industry Standard

Nitrogen plays a vital role in many industrial processes, so nitrogen generation is important in many industries. If your business uses nitrogen, either for manufacturing or other reasons, then it’s important to find a reliable source of nitrogen.

There are several different types of nitrogen generators that your business can choose from, including PSA (Pressure Swing Adsorption) nitrogen generators. PSA nitrogen generators provide high-purity nitrogen to businesses of all kinds.

If your business needs a nitrogen generator, pressure swing adsorption nitrogen generation can help your business obtain high-purity nitrogen at an affordable price.

Understanding PSA Nitrogen Generation

PSA nitrogen generators have two tanks that each contain a carbon molecular sieve. The generator fills one tank with air, then increases pressure inside the tank. The carbon molecular sieve adsorbs oxygen and other molecules.

Once the nitrogen has been separated from the various types of gas in the tank, the pressure swing adsorption nitrogen generator produces a high-purity stream of nitrogen. The other gases are ejected from the tank. PSA nitrogen generators have two tanks that alternate between pressurizing and depressurizing (this is the pressure swing process), allowing the generator to produce a continuous supply of nitrogen. Compared to other ways of obtaining nitrogen, such as cryogenic separation, PSA nitrogen generators have many advantages. 

  • They are more convenient than cryogenic nitrogen production.
  • It costs less over time when compared to nitrogen obtained through cylinders.

If your business could benefit from nitrogen generators, talk to On Site Gas Systems to learn more about whether PSA nitrogen generators can meet the unique needs of your business.

If your business relies on nitrogen for its industrial or manufacturing processes, then you need to understand nitrogen and the many options for obtaining nitrogen. This article is a guide to nitrogen generator technology and how it can streamline your business.

N2 Generation Technology

What Is a Nitrogen Gas Generator?

A nitrogen gas generator is a device that separates nitrogen from oxygen and other gases in the air. Nitrogen generators produce high-purity nitrogen on demand for businesses in many industries, including food and beverage industries, aerospace, electronics, oil and gas, automotive, and pharmaceuticals.

How Nitrogen Generation Technology Works

There are different nitrogen generator types. The two most common are membrane nitrogen generators and pressure swing adsorption nitrogen generators with each type having distinct benefits. When choosing a nitrogen generator for your business, it’s important to understand your nitrogen needs to select the right generator for your industry.

Membrane Nitrogen Generators

Membrane nitrogen generators operate through a selective permeation process. Compressed air enters the generator, which contains a membrane with polymer fibers. As the air is pushed into the polymer fibers, nitrogen and oxygen are separated. The generator produces a steady stream of nitrogen and expels oxygen as waste.

The advantages of membrane nitrogen generators include:

  • Continuous nitrogen production: Membrane nitrogen generators produce a reliable stream of nitrogen. In contrast with nitrogen cylinders, membrane nitrogen generators never need to be refilled or re-stocked.
  • Low-maintenance: Membrane nitrogen generators are relatively low maintenance. They contain no moving parts, making them easy to maintain and repair.
  • Energy-efficient: Membrane nitrogen generation technology is energy-efficient and requires relatively little energy.

Membrane nitrogen generators produce nitrogen that is the right purity for food packaging, oil and gas industries, tire inflation, and fire prevention.

Pressure Swing Adsorption (PSA) Nitrogen Generators

Pressure swing adsorption nitrogen generators get their name from the pressure swing adsorption process. The generator contains two pressure vessels. As one vessel is pressurized, the other is depressurized. These two vessels alternate between pressurizing and depressurizing while the unit operates.

During this process of pressurizing and depressurizing, the system uses adsorption to separate nitrogen from oxygen. Each vessel contains a special sieve that adsorbs carbon dioxide, oxygen, and impurities. This allows the generator to produce a steady stream of high-purity nitrogen while expelling oxygen.

The advantages of PSA nitrogen generators include:

  • High purity levels: PSA nitrogen generators produce nitrogen in high purity levels (up to 99.999%).
  • Flexible production capacity:</b >PSA nitrogen generators are flexible in their production capacity, and can ramp up or slow down nitrogen production as needed.

The Role of Membrane Nitrogen Technology in Sustainability Efforts

Nitrogen gas plays an important role in various manufacturing and industrial processes. From food packaging to the aerospace industry, there is a growing need for sustainable gas generation solutions in businesses of many types. Although businesses purchase nitrogen in cylinders and other types of packages, this method of nitrogen delivery has environmental and cost downsides.

In this article, we’ll discuss how membrane nitrogen technology delivers a continuous, reliable supply of nitrogen while contributing to commercial sustainability efforts. Membrane nitrogen technology gives businesses a way of generating their nitrogen through environmentally friendly means.

What Is Membrane Nitrogen Technology?

The air contains a combination of nitrogen and oxygen along with small amounts of other gases. Membrane nitrogen generators use a selective permeation process to separate nitrogen from oxygen.

In a membrane generator, compressed air is pushed into the unit. The membrane nitrogen generator contains polymer fibers in a membrane. Each fiber has tiny holes that can fit oxygen and other gas molecules, but not nitrogen. During the nitrogen generation process, gasses are passed through the holes in the fiber, separating oxygen from nitrogen. Oxygen is expelled as waste, and the membrane nitrogen generator produces a steady stream of nitrogen for industrial purposes.

There are many advantages to using a membrane nitrogen generator instead of a nitrogen cylinder or another form of nitrogen delivery. Some of those advantages include:

  • Less reliance on fossil fuels: Nitrogen cylinder delivery happens via vehicles that use fossil fuels. Membrane nitrogen generators use little power to function and thus can shrink your business’s carbon footprint.
  • Cost efficiency: In addition to being good for the environment, nitrogen generators are cost-efficient. Nitrogen generators are sold for a one-time cost, whereas nitrogen cylinders are rented or purchased for an ongoing cost. Over time, businesses with membrane nitrogen generators can save money compared to businesses that depend on nitrogen cylinders.
  • Requires little energy: Membrane nitrogen generators have low power consumption and few moving parts. They’re durable and long-lasting.

Sustainability Benefits of Membrane Nitrogen Technology

If your business prioritizes sustainability, there are many reasons to get a membrane nitrogen generator:

Energy Efficiency

Membrane technology has low energy consumption and the ability to supply nitrogen on demand. This helps reduce your business’s overall carbon footprint.

Reduction in Greenhouse Gas Emissions

Installing a nitrogen generator onsite eliminates the need for transportation of nitrogen cylinders, dewars, and other containers. On-site production minimizes fuel consumption and thus minimizes emissions. Since cryogenic nitrogen requires special storage conditions, membrane nitrogen generation can cut back on energy consumption in this way as well.

Waste Reduction and Resource Conservation

There are no byproducts or chemical waste in membrane nitrogen generation. Whereas single-use nitrogen cylinders and liquid nitrogen storage can produce waste, membrane nitrogen generators are virtually waste-free.

Long-Term Cost Savings

Membrane nitrogen technology has lower operational and maintenance costs than nitrogen cylinder delivery. Businesses that switch to membrane nitrogen generators enjoy reduced dependency on third-party nitrogen suppliers. Since these nitrogen suppliers can experience disruptions in service and problems with the supply chain, the result of using a generator is more consistent availability of nitrogen and long-term cost savings.

Eco-Friendly Applications

Nitrogen allows businesses to package and preserve food without harmful chemicals. Nitrogen also helps reduce environmental risks through inerting and blanketing, which prevents oxidation, moisture contamination, and combustion.

The Economic Advantages of Switching to On-Site Nitrogen Gas Generators

Nitrogen gas is used in many industries for various purposes including flushing out oxygen and preventing oxidation or corrosion of materials. Nitrogen is also useful because of its inert properties. It is non-reactive with various elements and can be used to create a stable environment. Nitrogen is used in the food and beverage industry, pharmaceuticals, steel welding, electronics manufacturing, and more.

Nitrogen may be delivered to businesses via cylinders, dewars, and bulk delivery. Nitrogen can also be drawn from the air and separated from other gases in the atmosphere using a nitrogen gas generator. Nitrogen gas generators save businesses money, and we’ll discuss the many benefits of nitrogen generators for your industrial purposes.

Traditional Nitrogen Supply Methods

Traditional nitrogen supply methods include cylinders, dewars, and bulk delivery.

  • Cylinders: Nitrogen cylinders are typically five feet tall and contain about 230 cubic feet of gaseous nitrogen. Cylinders are one of the most common nitrogen supply methods.
  • Dewars: A cryogenic dewar is a large container that holds a cold liquid. Dewars have a vacuum space between the cold liquid nitrogen and the outside world.
  • Bulk delivery: In bulk deliveries, liquid nitrogen is delivered through a tank and pumped into the truck on demand.

These delivery methods are all associated with hidden and recurring costs, such as rental fees and handling charges.

Nitrogen Generator

On-Site Nitrogen Generators: An Overview

On-site nitrogen generators are an alternative to traditional nitrogen delivery, such as cylinders and dewars.

  • Pressure Swing Adsorption (PSA) Nitrogen Generators: Pressure swing nitrogen generators have two cylinders that each contain a carbon molecular sieve for nitrogen adsorption. PSA nitrogen generators work by first pressurizing one cylinder and then another. During this process, the sieve adsorbs gases like oxygen, and the nitrogen is expelled from the generator in a continuous stream.
  • Membrane Nitrogen Generators: Membrane nitrogen generators separate nitrogen from other elements through a membrane.

Industries that Benefit from Nitrogen Production

Many industries benefit from nitrogen production, including:

  • Food and beverage: Nitrogen is used in food packaging. In this industry, nitrogen is used to flush oxygen from food packages, preventing foods from developing off-odors and flavors. Nitrogen can also be used in beverage packaging.
  • Pharmaceuticals: Nitrogen helps stabilize sensitive medications by creating an inert environment for medication packaging.
  • Aerospace: Nitrogen is used to create strong welds in the aerospace industry. N2 can also be used to displace air in fuel tanks.
  • Oil and gas industry: In the oil and gas industry, nitrogen is used to purge pipelines and tanks. Nitrogen is much safer than oxygen and can be used to prevent workplace accidents.

Key Economic Advantages

Cost Savings

Businesses that rely on nitrogen delivery pay a lot every month for delivery and handling fees, not to mention that the cost of the nitrogen is a lot higher than if you generate it with a On Site Gas Systems Nitrogen Generator. Nitrogen generators allow businesses to enjoy reduced dependency on external suppliers and save them money.

Predictable Operating Costs

Unlike nitrogen delivery services, nitrogen generators have a fixed cost structure. They also have minimal maintenance expenses. Nitrogen generators are energy-efficient technologies that ensure long-term savings for businesses.

Improved Operational Efficiency

Businesses that are dependent upon nitrogen delivery are at the mercy of their suppliers. When supply chain problems get in the way, businesses may not have the nitrogen they need when they need it. Having on-demand nitrogen reduces downtime, and enables businesses to remain operational.

Scalability and Flexibility

Nitrogen production from a nitrogen generator can easily be scaled up or down, based on business growth and demand. This tailored output allows your business to meet the needs of your customers without waiting for nitrogen suppliers to deliver more nitrogen.

Hidden Benefits of Onsite Nitrogen Generator

In addition to the benefits of onsite nitrogen generators named above, there are also hidden benefits of on-site nitrogen generation.

  • Environmental Savings: Using a nitrogen generator can help reduce your business’ carbon footprint. Nitrogen generators are energy-efficient and do not require regular delivery from trucks that use fossil fuels.
  • Increased Safety: Storing high-pressure nitrogen cylinders can be dangerous for employees, but using a nitrogen generator can reduce the risk of accidents at the workplace.
  • Operational Autonomy: On-site nitrogen generation gives your business full control over your nitrogen supply without reliance on third parties.
