Combined Modular Nitrogen Generator

Our combined modular nitrogen generator cleverly integrates the refrigerated dryer, precision filtration system, air buffer tank, nitrogen buffer tank, and modular nitrogen generator into a single unit, fulfilling multiple functions with just one device. Users only need to connect the air inlet to the air compressor and the nitrogen outlet to the gas application for immediate nitrogen supply, no complex installation or commissioning required. The compact, all-in-one design saves space, boosts efficiency, and provides you with an efficient, convenient gas supply solution!

Product Characteristic

▔▔▔

User-Friendly Touch Screen

An intuitive PLC interface delivers a smooth and efficient user experience, reducing training time and operational errors

High-Quality Stainless Steel Valves

All pneumatic valves are manufactured from premium 304 stainless steel, offering high pressure resistance, corrosion protection, and over 2 million reliable switching cycles

Plug-and-Play Design

Filters, refrigerated air dryer, piping, and nitrogen generation components are fully integrated into a single enclosure, enabling rapid startup and true plug-and-play operation

Application

▔▔▔

Tire Filling

Tire inflation applications require small nitrogen flow at 95–99% purity to improve tire pressure stability, reduce oxidation, and extend tire lifespan

Fire Suppression & Inert Storage

Fire prevention and inert storage applications typically use small nitrogen volumes at 95–99% purity to reduce oxygen levels and minimize combustion risks

Additive Manufacturing

Metal additive manufacturing uses medium nitrogen consumption at 99.99–99.999% purity to maintain inert build environments and prevent powder oxidation

FAQ

▔▔▔

Why choose a combined modular nitrogen generator?

This system combines all critical components—refrigerated dryer, filtration system, air buffer tank, nitrogen buffer tank, and the modular PSA generator—into one compact, plug-and-play unit. Simply connect the air and nitrogen lines and you're ready to go. The all-in-one design improves efficiency, reduces space usage, and simplifies nitrogen supply management.
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.
How is nitrogen purity ensured during operation?

High-quality carbon molecular sieves, precise valve switching, and PLC-controlled cycle timing work together to maintain stable and consistent nitrogen purity.
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.
