Product Description

Combined Nitrogen Generator
One skid solves it all!
Our compact nitrogen generator integrates a refrigerated air dryer, a precision filtration system, an air buffer tank, a nitrogen buffer tank, and a dual-tower nitrogen generator into a single skid-mounted unit. Users simply need to connect the air inlet to an air compressor and the nitrogen outlet to the nitrogen application. This design greatly optimizes the user experience by eliminating the need for installation and commissioning, saving both space and time, while providing a more efficient and convenient gas supply solution.

Product Overview

Pressure Swing Adsorption Technology
Pressure Swing Adsorption (PSA) is a gas separation technology. Its principle is based on the difference in the adsorption properties of different gas molecules by an adsorbent (such as carbon molecular sieve), which allows the separation of gas mixtures. This technology uses air as the raw material and employs highly efficient, highly selective adsorbents to selectively adsorb nitrogen from the air, thereby achieving nitrogen-oxygen separation.

Product Applications

Rubber & Tire
Our nitrogen generators in the tire and rubber industry are mainly used for atmosphere control in rubber mixing and vulcanization processes. By using nitrogen in these processes, an inert atmosphere environment can be formed, effectively preventing oxidation and degradation of rubber materials at high temperatures.
