Nitroxtec Deoxy Nitrogen Purification Unit

Take Your Nitrogen to the Ultra-Pure Level.

Nitroxtec Deoxy systems are designed to purify nitrogen gas generated by PSA systems, increasing purity from 99.9% up to 99.9999% (6.0 grade). The system employs a catalytic reaction using hydrogen to eliminate residual oxygen. The resulting water vapor is efficiently removed using an integrated chemical dryer, producing dry, oxygen-free, high-purity nitrogen for sensitive industrial applications.

Thanks to its compact design, low energy consumption, and intelligent control system, the Nitroxtec Deoxy Unit is ideal for industries requiring stable, cost-effective, and uninterrupted ultra-high-purity nitrogen.

Working Principle

Nitrogen gas exiting a PSA generator at ~99.9% purity enters the Deoxy Unit, where it is mixed with a precise amount of hydrogen. The gas stream then passes through a palladium-coated alumina catalyst. In this stage, residual oxygen reacts with hydrogen, forming water vapor (H₂O). The resulting humidity is eliminated by a downstream chemical dryer, ensuring a dry, oxygen-free nitrogen output.

The entire process is monitored and controlled by a fully automated PLC system that regulates hydrogen dosing and drying efficiency—ensuring low operating costs and high reliability.
