Gaztronā€™s PSA Nitrogen (N2) Gas Generator Payback

If your business relies on a steady supply of nitrogen, you're likely all too familiar with the challenges of renting and delivering bulky nitrogen cylinders. Not only do they take up valuable floor space and pose safety risks, but the associated costs, downtime, and contractual obligations can add up. While the initial investment may seem daunting, Gaztron's nitrogen generators typically pay for themselves in approximately 12 months, making them essentially free to operate after that point. Plus, you'll have the peace of mind of a reliable, cost-effective nitrogen supply that's under your control.

Frequently Asked Questions

Have a question? Check out our frequently asked questions to find your answer.

Can we get a nitrogen generator tailored to our exact nitrogen gas demand?

Yes, Nitrogen Generators are customized to customer’s specifications for Purity and Capacity.

Nitrogen Generators are customizable to achieve Nitrogen Purity ranging from 95% to 99.9998%.

Typically, 45 days.

Nitrogen Generators operate autonomously and do not require continuous supervision once started.

The Gas generator comes fully assembled on steel frames and can be placed on the floor. After connecting power, it’s ready for start-up. We offer Engineer services for on-site installation and commissioning supervision.

Molecular Sieves typically last for around 10 years, often lasting the entire lifetime of the Gas generator.

An Oxygen Analyzer monitors Nitrogen purity and automatically shuts down the Gas generator with an alarm if the purity falls below the set limit.
