Nitrogen Gas Generator for Grain Preservation Reduce Storage Loss and Maintain Quality

99.5% 150Nm3/h Nitrogen Generator for Grain Storage Reduce Mold Growth and Insect Damage Effectively Nitrogen Gas Generator for Grain Preservation Reduce Storage Loss and Maintain Quality Nitrogen generator PSA Nitrogen generator

Zhongsu Hengda's PSA nitrogen generator is specifically engineered for grain storage scenarios, integrating a complete, industrial-grade pressure swing adsorption (PSA) nitrogen production system to deliver 99.5% purity nitrogen—an efficient, chemical-free inert gas solution for inhibiting mold growth and pest infestations in grain storage facilities.

Tailored to meet the core needs of grain silos, bulk warehouses, and medium-to-large-scale storage depots, this system focuses on stable, targeted inerting: it effectively reduces oxygen levels in storage spaces to below 5% (the critical threshold that halts mold reproduction and eliminates pest survival) while maintaining grain moisture balance, ensuring no damage to grain quality or nutritional value. With a flexible flow range of 3-2000Nm³/h, it precisely matches the gas demand of diverse storage scales—from small warehouses to 10,000-ton-class silos—adapting seamlessly to batch or continuous grain storage workflows.

Designed for ease of integration into existing grain storage setups, it features a compact, modular structure that fits standard warehouse or silo auxiliary spaces, requiring minimal on-site preparation. The pre-tested core components (including air compressors, high-efficiency dryers, and PSA nitrogen generators) and quick-connect interfaces enable fast commissioning—getting the system up and running in a short time to avoid delays in grain protection.
