Combined Nitrogen Generator

Our compact nitrogen generator integrates a refrigerated air dryer, a precision filtration system, an air buffer tank, a nitrogen buffer tank, and a dual-tower nitrogen generator into a single skid-mounted unit. Users simply need to connect the air inlet to an air compressor and the nitrogen outlet to the nitrogen application. This design greatly optimizes the user experience by eliminating the need for installation and commissioning, saving both space and time, while providing a more efficient and convenient gas supply solution.

FAQ

▔▔▔

Why choose our combined nitrogen generator?

Our combined nitrogen generator integrates a refrigerated dryer, precision filtration system, air buffer tank, nitrogen buffer tank, and dual-tower PSA nitrogen generator into a single skid-mounted unit. Users simply connect the air inlet to a compressor and the nitrogen outlet to their application. The compact system eliminates the need for installation and commissioning, saving time and space while providing a streamlined gas solution.
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.
