Nitrogen Generators vs Cylinders: The Superior Solution for Ease of Use in Industry
Nitrogen is one of the most widely used gases in industries ranging from manufacturing and pharmaceuticals to food packaging, electronics, and chemical processing. Whether used for blanketing, purging, pressurizing, or inerting, nitrogen plays a critical role in ensuring product quality and safety in a wide array of industrial applications. Historically, industries have relied heavily on nitrogen cylinders as their primary source of nitrogen. However, in recent years, nitrogen generators have increasingly gained popularity as a more convenient, efficient, and cost-effective alternative.
In this blog, we’ll explore the differences between nitrogen generators and nitrogen cylinders, with a particular focus on why nitrogen generators offer superior ease of use. By the end, it should be clear why more industries are transitioning from traditional cylinders to modern nitrogen generators for their nitrogen needs.

Nitrogen Cylinders: Traditional but Tedious
Nitrogen cylinders have long been the go-to method for industries requiring nitrogen. These high-pressure tanks, filled with compressed nitrogen gas, are delivered to a facility and stored until needed. While this method has served its purpose for many years, it comes with several disadvantages that directly affect ease of use.
The Process of Using Nitrogen Cylinders
Using nitrogen cylinders may seem straightforward, but it involves several steps that can be cumbersome for industrial operations:
1. Ordering and Delivery: Businesses must continually monitor their nitrogen usage to avoid running out of supply. This means regular orders must be placed for cylinder refills or new cylinders. Deliveries require coordination with suppliers, which can become complex if there are delays or fluctuations in demand.
2. Handling and Storage: Nitrogen cylinders are heavy and bulky, requiring manual labor or equipment to move them from storage areas to the point of use. In industries with high nitrogen demand, large numbers of cylinders must be stored on-site, often consuming valuable space.
3. Swapping Cylinders: Once a cylinder runs out, it must be swapped for a full one. This process interrupts operations, creating downtime and requiring personnel to stop what they’re doing and replace the tank.
4. Safety Concerns: Compressed gas cylinders are highly pressurized, which presents inherent safety risks. Mishandling or improper storage of cylinders can lead to accidents, including explosions or gas leaks. Additionally, regulatory compliance is required for handling and storing high-pressure cylinders, which adds to the administrative burden.
5. Waste and Inefficiency: When cylinders are returned to suppliers, some nitrogen may still be left inside, which leads to wasted gas. The need to monitor gas levels constantly also means additional time and resources must be devoted to managing the supply.
Given these challenges, it becomes clear that relying on nitrogen cylinders for industrial operations can be time-consuming, costly, and inefficient. This has prompted many businesses to explore alternative nitrogen supply options.

Nitrogen Generators: The Modern, Convenient Solution
In contrast to nitrogen cylinders, nitrogen generators offer a more seamless and efficient method of obtaining nitrogen for industrial use. Nitrogen generators work by extracting nitrogen directly from the ambient air using either Pressure Swing Adsorption (PSA) technology or membrane technology. These machines are designed to provide a continuous, on-demand supply of nitrogen with minimal human intervention.
How Nitrogen Generators Work
Nitrogen generators utilize the fact that air is composed of about 78% nitrogen. They separate nitrogen molecules from other components, such as oxygen and argon, through either PSA or membrane filtration methods:
• PSA Technology: PSA nitrogen generators use a carbon molecular sieve to adsorb oxygen and other gases, allowing only nitrogen to pass through. The system alternates between two sieve beds to maintain a constant nitrogen flow.
• Membrane Technology: Membrane nitrogen generators use semi-permeable membranes that allow oxygen and water vapor to diffuse out while nitrogen is retained, providing a consistent nitrogen stream.
These technologies allow for nitrogen to be generated on-site, providing numerous advantages over traditional cylinder usage.

Ease of Use: Nitrogen Generators vs Cylinders
Let’s take a closer look at how nitrogen generators improve ease of use over nitrogen cylinders.
1. On-Demand Supply
One of the most significant advantages of nitrogen generators is their ability to provide an uninterrupted, on-demand supply of nitrogen. Unlike nitrogen cylinders, which require constant monitoring and reordering, nitrogen generators can produce nitrogen as needed. This eliminates the risk of running out of gas during critical operations and eliminates the hassle of scheduling deliveries.
In industries with fluctuating nitrogen demand, nitrogen generators automatically adjust production based on real-time usage, meaning there’s no need for human intervention to manage the supply. This feature alone dramatically simplifies nitrogen management and reduces operational downtime.
2. No Cylinder Handling or Storage
With nitrogen generators, there’s no need for bulky cylinders taking up valuable space in your facility. Nitrogen is generated on-site, meaning storage space previously occupied by cylinders can now be repurposed for more productive use. Additionally, since there are no cylinders to move, there’s no risk of injury or damage due to manual handling, making for a safer workplace.
For industries with high nitrogen consumption, the labour savings from eliminating the need to move cylinders is substantial. Nitrogen generators free up employees to focus on more important tasks, improving overall productivity.
3. Continuous Flow and Uninterrupted Operation
In industries where nitrogen is used continuously, such as in chemical processing or food packaging, interruptions due to cylinder replacements can cause significant operational disruptions. With a nitrogen generator, the supply of nitrogen is consistent and uninterrupted. There’s no need to pause operations to replace empty tanks or check gas levels, allowing for smoother, more efficient processes.
In fact, many nitrogen generators are equipped with backup systems to ensure redundancy, so that even in the rare event of a malfunction, nitrogen flow remains uninterrupted.
4. Cost-Effectiveness
While nitrogen generators require an upfront investment, they often result in significant cost savings in the long term. With nitrogen cylinders, businesses pay for each delivery, incur rental fees for the cylinders, and face costs associated with gas waste. In contrast, nitrogen generators allow for the production of nitrogen at a fraction of the cost of purchasing it in cylinders.
Additionally, the reduction in labour required for handling, monitoring, and ordering nitrogen further adds to the overall cost savings. Maintenance costs for nitrogen generators are also generally low, and modern systems are designed for longevity, making them a cost-effective choice in the long run.
5. Improved Safety
Nitrogen generators eliminate the need for storing and handling high-pressure gas cylinders, reducing the safety risks associated with traditional cylinder use. There’s no risk of cylinder leaks, explosions, or accidents caused by improper handling. Furthermore, nitrogen generators produce nitrogen at the purity levels required for specific applications, ensuring optimal performance and safety in critical processes.
Many nitrogen generators come equipped with advanced monitoring and safety systems that provide real-time data on nitrogen purity, pressure, and flow, giving operators greater control and confidence in their nitrogen supply.
6. Environmentally Friendly
Switching from nitrogen cylinders to nitrogen generators is also beneficial from an environmental perspective. With on-site nitrogen generation, there’s no need for the constant transportation of cylinders, reducing the carbon footprint associated with deliveries. Additionally, the elimination of cylinder waste means that businesses can reduce their overall environmental impact.
Nitrogen generators require only electricity to operate, and many modern systems are energy-efficient, further contributing to environmental sustainability.
