Switching to onsite nitrogen generation offers substantial benefits for businesses that rely on a steady nitrogen supply. If your operations require nitrogen for applications like food packaging, pharmaceuticals or electronics, here are some key reasons why onsite nitrogen generation might be the best choice for your business.
Is Onsite Nitrogen Generation Right for You?
Deciding whether onsite nitrogen generation is the right choice for your business depends on several factors, including your nitrogen consumption volume, purity requirements, cost considerations, and operational priorities. Deciding whether onsite nitrogen generation is right for your business involves evaluating several key factors:
-
Nitrogen consumption volume: If your business uses large or continuous volumes of nitrogen, such as in manufacturing, food and beverage processing, pharmaceuticals, or electronics, onsite generation can provide a reliable and cost-effective solution.
-
Purity requirements: Onsite systems can be tailored to produce nitrogen at specific purity levels to meet the needs of applications like inerting, purging, blanketing, and modified atmosphere packaging.
-
Current costs: High delivery and rental fees for bulk tanks or cylinders may make onsite generation more economical in the long run.
- Supply reliability: If delivery delays or fluctuating nitrogen needs disrupt operations, onsite generation ensures a steady, on-demand supply without reliance on external providers.
Benefits of Onsite Nitrogen Generation
Switching from contact nitrogen delivery to onsite nitrogen generation offers several compelling benefits, especially for businesses that rely heavily on nitrogen for their processes. Onsite nitrogen generators provide a reliable, cost-effective, and customizable alternative to traditional nitrogen delivery methods, such as gas cylinders or bulk liquid tanks and dewars. Here are some reasons to make the switch.
1. Significant Cost Savings
Onsite nitrogen generation is a cost-effective alternative to delivered nitrogen, especially for high-usage facilities. It eliminates recurring expenses such as delivery fees, cylinder rentals, and gas waste — helping you save up to 50–80% compared to traditional supply methods.
With the ability to produce nitrogen on demand, businesses can reduce overhead and achieve ROI in 8–18 months. Cost control improves further with freedom from price fluctuations, delivery delays, and contract constraints.
2. Reliable, On-Demand Supply
Onsite nitrogen generation means you have a steady supply of nitrogen whenever you need it, eliminating the risk of delays or shortages. This constant access to nitrogen supports seamless operations, as there’s no need to wait for cylinder replacements or worry about running out during critical processes. By choosing onsite generation, you can avoid downtime and maintain efficiency, especially in industries where nitrogen is essential for preserving product quality or ensuring safety.
3. Total Control Over Purity and Flow
With onsite nitrogen systems, you have full control over nitrogen purity and flow rate, allowing you to tailor the supply to your specific needs. Onsite systems allow businesses to produce nitrogen at required purity levels for specific applications, from food packaging to industrial processes. For applications that require high purity — such as pharmaceutical manufacturing or electronics assembly — PSA nitrogen generators can deliver up to 99.999% nitrogen purity. Meanwhile, membrane systems are an excellent choice for applications with moderate purity requirements, like food packaging or inerting. By tailoring nitrogen purity requirements to the application, manufacturers can avoid paying for higher nitrogen purity than needed or ensure that the supply meets more stringent purity requirements.
The system can also be designed and sized around specific flow requirements. Membrane generators produce nitrogen continuously at moderate flow rates, depending on the size and number of membrane modules. PSA generators produce continuous nitrogen on demand. That means businesses can adapt to changing production demands without needing to adjust delivery schedules or storage capacity.
4. Reduced Environmental Impact
Onsite nitrogen generation offers a more sustainable alternative to delivered nitrogen, reducing the carbon footprint associated with transportation and storage. By generating nitrogen on-site, you can eliminate frequent deliveries and the emissions linked to transportation and handling of high-pressure cylinders. This sustainability factor not only supports environmental goals but also demonstrates your business’s commitment to eco-friendly practices, which can be a valuable asset in today’s market.
5. Operational Efficiency
Managing nitrogen deliveries involves tracking inventory, arranging for replacements and dealing with the logistics of high-pressure cylinders or bulk storage tanks. Onsite nitrogen generation simplifies this process by producing nitrogen right in your facility on demand. There is no need to stop production to change cylinders, and the headaches of managing delivery schedules and cylinder or dewar return are eliminated.
Both PSA and membrane nitrogen generators are designed with low maintenance requirements and are straightforward to operate, freeing up time and resources for other critical tasks. Additionally, your system provider can often offer maintenance services to ensure long-term performance. While maintenance is minimal, system longevity depends on clean, dry air. Regular upkeep of compressors, filters, and dryers is essential, especially for PSA units.
6. Safety
Onsite nitrogen generation significantly enhances workplace safety by eliminating the need to handle and store high-pressure cylinders or large bulk tanks. This reduces the risks associated with transporting, lifting and connecting heavy gas containers, as well as the potential for leaks or accidents during handling. By producing nitrogen on demand and at lower pressures, these systems provide a safer alternative to traditional delivery methods, ensuring compliance with safety standards and minimizing hazards for employees.
7. Storage and Space Optimization
Switching to onsite nitrogen generation can also free up valuable space in your facility. Traditional nitrogen delivery often requires significant storage space for cylinders or bulk tanks, which can clutter workspaces and limit operational flexibility.
Onsite systems are compact and streamlined, taking up a fraction of the space while providing a continuous supply of nitrogen. This not only improves workflows but also allows businesses to repurpose storage areas for other critical needs.
For optimal performance, generators should be installed near key utilities like compressed air and electricity. PSA systems, in particular, require clean, dry air and may need temperature and humidity control for consistent output.
Industries and Applications for Onsite Nitrogen Production
Onsite nitrogen generation is particularly advantageous for industries that require a consistent, high-quality supply of nitrogen to maintain critical processes and meet stringent operational standards. Whether the need is for inerting, purging, blanketing or specialized packaging, businesses in these industries often find that onsite systems offer greater reliability, cost savings and efficiency compared to traditional nitrogen delivery methods. Below are some of the industries and their key applications where onsite nitrogen generation can provide the most value.
-
Food & beverage processing: Onsite nitrogen generation ensures freshness and extends shelf life in food and beverage applications like modified atmosphere packaging, inerting, and carbonation. It provides a consistent, high-purity supply to protect product quality and streamline operations.
-
Manufacturing and metalworking: Manufacturers use onsite nitrogen for welding, laser cutting, and purging to prevent oxidation and ensure precision. It supports processes like injection molding, reducing defects and improving efficiency.
-
Pharmaceuticals and chemicals: Onsite nitrogen protects sensitive materials from oxygen and moisture, ensuring product stability. It supports sterile environments, purging, and packaging, which is critical for pharmaceutical and chemical processes.
-
Electronics and semiconductors: Electronics manufacturing relies on onsite nitrogen for soldering, assembly, and testing. It ensures clean, oxygen-free environments to prevent oxidation and protect sensitive components.
