On-Site Nitrogen Generation Solutions in San Jose, CA
Enhance Efficiency with On-Site Nitrogen Generation Systems
Many commercial and industrial facilities rely on nitrogen in their daily operations. Along with compressed air and natural gas, it is a key gas that provides protection for products, operations, and equipment. If you feel you’re spending too much money on procuring nitrogen or want to handle the production of it yourself, the team at D & D Compressor, Inc. will help you. We can provide you with an on-site membrane or PSA nitrogen generator for your San Jose, CA facility. Please keep reading to learn more about on-site nitrogen production and the benefits it can offer you, your crews, and your productivity.
How On-Site Nitrogen Generation Works
On-site nitrogen generation involves taking the air that’s already in your facility, compressing and cleaning it, then separating the nitrogen for continued use. There are two primary kinds of it: PSA generation and Membrane generation. Here’s how both kinds generally work:
- Compressing the Air: Your existing air compressor supplies clean, dry compressed air to the nitrogen generator.
- Cleaning and Conditioning: Before separation, the air passes through filters and a dryer to remove oil, particles, and moisture.
- Separating the Nitrogen: Inside the generator, a separation technology (PSA or membrane) removes oxygen, water vapor, and other gases.
- Collecting the Nitrogen: The purified nitrogen exits the generator and is sent directly to the point of use. Or, it is sent to a storage or buffer tank.
What is a PSA Nitrogen Generator?
A PSA nitrogen generator makes nitrogen gas from compressed air using a process called Pressure Swing Adsorption. The unit comprises two vessels filled with a special adsorbent material called carbon molecular sieve (CMS). When clean, dry compressed air enters one vessel, the CMS captures oxygen, moisture, and carbon dioxide. Then, nitrogen passes through as the product gas. Once that vessel is saturated, the system reduces its pressure, so the adsorbed gases are released and vented. Then, the other vessel takes over nitrogen production.
What is a Membrane Nitrogen Generator?
A membrane nitrogen generator makes nitrogen gas from compressed air using semi‑permeable membranes instead of adsorption towers. Inside the unit is a membrane module packed with thousands of hollow polymer fibers that let different gases pass at different speeds. When clean, dry compressed air flows through these fibers, gases like oxygen, water vapor, and CO₂ go through the fiber walls and are vented away. Nitrogen stays inside the fibers and continues to the outlet as product gas.
PSA vs. Membrane: How Do They Compare?
Do you need help deciding whether a PSA or membrane nitrogen generator is right for you? Here’s a brief breakdown of their differences and what purposes they are best suited for:
- Nitrogen Purity Levels: Generally, PSA works better when you need high or ultra‑high purity nitrogen. But a membrane generator will suffice if you need moderate purity.
- Applications and Purposes: PSA is often chosen for laser cutting, metal heat treatment, electronics, pharmaceuticals, and lab use. If you blanket and purge chemical or food tanks, then a membrane generator will likely be a good fit.
- Maintenance: Since they don’t have moving parts, membrane generators are usually easier to maintain and service. Though PSAs are long-lasting, they may require more maintenance and care.
The Benefits of an On-Site Nitrogen Generation System
If you want to make the switch to on-site nitrogen production, you’re in luck. The following are just a few of the benefits that it can provide for you:
- On-Demand Availability: PSA and membrane generators can produce nitrogen on demand 24/7. So, you won’t have to wait for delivery trucks or worry about suddenly running out of nitrogen.
- Cost Savings: In general, on-site nitrogen generation can help facilities drive down their expenses. That’s because it eliminates the need to pay outside nitrogen suppliers and supply costs.
- Nitrogen Purity Control: Many PSA and membrane systems can be adjusted and customized to the unique needs of your operation. Their built-in controls can help you control and change your nitrogen’s purity levels as needed.

FAQs
That will depend on the size of your generator and the level of production needed. In general, smaller systems may cost in the tens of thousands, while large, high‑purity industrial units will likely cost much more than that.
On-site systems can cut per‑unit nitrogen costs in many applications.
Hopefully, yes. An on-site nitrogen generator produces nitrogen from compressed air at your facility and eliminates the need for delivered nitrogen. This can cut down on your waiting times, fees, and other logistical and operational inefficiencies.
