Frequently Asked Questions About Nitrogen Generators
What is a PSA nitrogen generator?
A PSA (Pressure Swing Adsorption) nitrogen generator separates nitrogen from compressed air using carbon molecular sieves (CMS). It produces high-purity nitrogen on-site, eliminating the need for delivered liquid nitrogen or cylinders.
How much does a nitrogen generator cost?
The cost depends on flow rate, purity, and application. Our systems range from compact units for small labs to large industrial systems. Most customers achieve full ROI within 12-18 months through savings on gas purchases. Contact us for a custom quote.
What purity levels can your nitrogen generators produce?
Our PSA nitrogen generators produce nitrogen with purity from 95% to 99.999% (5N). The purity level can be adjusted to match your specific application requirements — from food packaging (97-99%) to SMT soldering (99.99-99.999%).
How long do PSA nitrogen generators last?
This is a placeholder tab content. It is important to have the necessary information in the block, but at this stage, it is just a placeholder to help you visualise how the content is displayed. Feel free to edit this with your actual content.
What maintenance is required for a nitrogen generator?
Regular maintenance includes: replacing air filters every 3-6 months, checking valve operation annually, replacing CMS every 8-10 years, and calibrating purity sensors. Our systems feature automated monitoring to simplify maintenance scheduling.
