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!

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

▔▔▔

Is nitrogen flow adjustable?

Yes. Nitrogen flow can be precisely adjusted via the flow control valve to match your anytime production requirements.
Can the system run 24/7 continuously?

Yes. All systems are designed for fully automated, unattended 24/7 continuous operation.
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.
