Quad-Tower Nitrogen Generator

Our quad-tower system integrates two sets of adsorption vessels into a single unit, replacing the traditional dual-tower setup. This design significantly simplifies the system structure, reduces footprint and installation costs, and greatly minimizes operational and maintenance complexity. The integrated system not only enhances operational efficiency and stability but also eliminates potential issues arising from multi-device coordination, making it a more economical and efficient all-in-one solution.

FAQ

▔▔▔

Why choose on-site nitrogen generation instead of liquid or bottled nitrogen?

On-site nitrogen generation offers lower investment and operating costs, requires less space, and is easier to manage and maintain compared to liquid or bottled nitrogen supply.
How does the operating cost of on-site nitrogen generation compare to liquid or bottled nitrogen supply?

The operating cost of on-site nitrogen generation is significantly lower due to the elimination of transportation, rental, and storage fees.
Is on-site nitrogen generation suitable for small businesses?

Yes, it’s highly suitable. With a quick return on investment, small businesses often gain greater cost advantages using on-site nitrogen generators.
How does on-site gas equipment ensure gas purity and stability?

Each unit is rigorously factory-tested to meet purity, flowrate, and performance standards. With regular maintenance, the system provides stable and reliable nitrogen output.
What is PSA?

Pressure Swing Adsorption (PSA) is a gas separation technology that relies on the different adsorption properties of gas molecules on adsorbents like carbon molecular sieves. It uses air as the raw material to selectively remove oxygen, allowing for the efficient separation and production of nitrogen.
Can a PSA nitrogen generator operate continuously?

Yes, it is designed for 24/7 continuous operation.
How often does the adsorbent in a nitrogen generator need replacement?

With proper maintenance, the molecular sieve typically lasts up to 5 years.
What is the typical maintenance cost for a nitrogen generator?

It depends on the size and configuration of the unit.
