What to Look For in a Nitrogen Generator Supplier

You've decided that producing on-site nitrogen is going to be something beneficial for your business - great! Now what? It is important to choose a reputable and experienced nitrogen generator supplier to help you choose the best unit for your business' application. Keep in mind these 5 guidelines when you are searching for a nitrogen generator supplier:

1. How many generator options does the nitrogen generator supplier offer? Do they have several unit options to assist a wide variety of businesses? How much do they know about the systems they offer? Are they able to distinguish the difference between membrane nitrogen generators and PSA nitrogen generators?
2. Which country is the generator manufactured in? Generators made outside of North America have  different standards that can greatly affect the capabilities and performance of an application. Ensure the money you invest in a nitrogen generator will give you results you desire.
3. Years in Business - Look for companies whose only business is nitrogen generation which a minimum of 5 years experience.
4. Are nitrogen generator units adjustable to varying nitrogen needs? Nitrogen generators should be a long-term investment for your business - ask your supplier if the unit you are investing in can be expandable to account for nitrogen demand increases or decreases in the future.
5. Testimonials/Successes in Past - Don't be afraid to ask the nitrogen generator supplier if they have sold similiar units to other businesses like yours. It is important the supplier knows and understands the functionality of your industry to ensure the nitrogen generator they suggest to you will perform the tqask you require.

These are 5 general guidelines you should adhere to when looking into a nitrogen generator supplier. Don't be afraid to ask questions and explore your nitrogen generation options.

What Kind of Generator is Best for You?

So you've made the decision to utilize on-site nitrogen production - but what nitrogen generator is best for your industry's application? CGT can help!

Generally speaking there are two types of nitrogen generators: Membrane Nitrogen Generators and PSA Nitrogen Generators. Check out both types and decide which one is best for you.

Membrane Technology

Membrane technology works by filtering oxygen from the dry compressed air stream via hundreds of thousands of hollow, polymeric fibers each the diameter of a human hair to produce gaseous nitrogen. The purity of the nitrogen (O2 Content) can be adjusted by regulating the volume of air passed through the membrane. Membrane modules can be added as necessary, so it's easy to expand as requirements change.

Membrane nitrogen generators are typically used in applications where the purity requirement is below 99.5% (0.5% O2 of higher).





PSA (Pressure Swing Adsorption) Technology

PSA technology utilizes two towers which are filled with carbon molecular sieve (CMS). Compressed air enters the bottom of the "online" tower and flows up through the CMS. Oxygen and other trace gases are preferentially adsorbed by the CMS, allowing nitrogen to pass through. After a pre-set time the on-line tower automatically switches to the regenerative mode, venting contaminants from the CMS. Carbon molecular sieve differs from ordinary activated carbons as it has a much narrower range of pore openings. This allows small molecules such as oxygen to penetrate the pores and separate from nitrogen molecules which are too large to enter the CMS. The larger molecules by-pass the CMS and emerge as nitrogen gas.

PSA nitrogen generators are typically used in applications where the purity requirement is higher than 99.5% (0.5% O2 or below).
