Process Introduction

At a certain temperature, residual oxygen in ordinary nitrogen reacts with carbon catalyst through oxidation to produce carbon dioxide (which can be removed by pressure swing adsorption). High-purity nitrogen is then obtained through further purification.

Dual Deaerator Design

The dual deaerator structure ensures minimum system resistance. It automatically alarms and switches deaerators when resistance increases, guaranteeing stable operation.

High-Purity Nitrogen Output

Adopts high-activity carbon deoxidizer with large adsorption capacity and low operating cost. Nitrogen purity is stably above 99.999%, unaffected by flow fluctuations.

Intelligent Operation

Human-machine interface displays operating parameters and automatically alerts for carbon deoxidizer replacement. Key components are high-quality imported parts supporting long-term continuous operation. Fully automatic switching realizes unmanned operation.

Energy Saving & High Efficiency

A large amount of moisture is removed through heat exchange and cooling, reducing water content with remarkable energy-saving effect.

Safe & Reliable

Equipped with multiple interlock control functions and sound-light alarm system, detecting and resolving problems timely to ensure product quality and equipment safety.
