Introduction

A CU De-Oxo Nitrogen Gas Plant is an advanced nitrogen purification system designed to produce ultra-high purity nitrogen gas up to 99.9999% with oxygen content ≤1 PPM.
This system is widely used in industries where extremely low oxygen levels are critical for product quality, safety, and process reliability.

AmsaAir Engineering Pvt. Ltd. designs and manufactures custom-engineered CU De-Oxo Nitrogen Gas Plants with fully automatic operation, high reliability, and long service life.

What is a CU De-Oxo Nitrogen Gas Plant?

A CU De-Oxo Nitrogen Gas Plant is an advanced purification system used to produce ultra-high purity nitrogen gas by removing trace oxygen from nitrogen. It is specially designed for applications where very low oxygen levels (≤1 PPM) are required.

In this process, nitrogen from a PSA nitrogen plant passes through a CU De-Oxo reactor containing a copper catalyst. A controlled amount of hydrogen reacts with the remaining oxygen and converts it into water vapor. This moisture is then removed by a high-efficiency dryer, resulting in dry, oxygen-free nitrogen gas with stable and consistent purity.

Key Features – CU De-Oxo Nitrogen Gas Plant

The CU De-Oxo Nitrogen Gas Plant is a highly advanced nitrogen purification system engineered to deliver ultra-high purity nitrogen gas up to 99.9999% by reducing residual oxygen content to ≤1 PPM. This plant is specially designed for industries where even trace amounts of oxygen can affect product quality, safety, or process stability.

The system works by passing nitrogen gas through a CU De-Oxidation reactor filled with a high-activity copper catalyst. A precisely controlled quantity of hydrogen is injected into the nitrogen stream, where it reacts with residual oxygen and converts it into water vapor. The generated moisture is then removed through a high-efficiency drying system, ensuring dry, stable, and ultra-pure nitrogen output.

The CU De-Oxo Nitrogen Gas Plant operates on a fully automatic, continuous 24×7 basis with PLC-HMI-based control, eliminating the need for manual intervention during normal operation. Optimized hydrogen dosing and energy-efficient design help minimize operating costs while maintaining consistent purity even during load variations. The plant is available in compact skid-mounted or containerized configurations, allowing easy installation and seamless integration with existing air compressor and nitrogen generation systems.

Built with robust industrial components, advanced safety interlocks, and alarm systems, the CU De-Oxo plant ensures safe and reliable performance over a long service life. Optional remote and mobile-based monitoring enables users to supervise and control complete plant operations anytime, anywhere, making it an ideal solution for critical industrial applications requiring ultra-high purity nitrogen.
