It is a high-purity flammable gas, used in ammonia synthesis and hydrogen energy etc. Hydrogen produced via PSA technology with a purity ≥ 99.5% serves as a clean energy source with zero pollution and high energy density.
Its main industrial applications include ammonia synthesis, methanol production, petroleum refining and organic hydrogenation; emerging applications cover hydrogen fuel cells, green metallurgy and high-purity electronics manufacturing.

High-purity oxygen is used for medical rescue and hyperbaric oxygen therapy. Produced via our cryogenic separation method, it ensures stable supply and has highlighted critical importance in COVID-19 treatment with proven safety and efficacy.

High-purity rare gases (with krypton purity ≥99.999% and xenon purity ≥99.9995%) are applied in semiconductors, aerospace and other fields. Extracted through our air separation systems, the gases feature a stable supply chain and high technical thresholds.

High-purity oxidant (purity ≥99.5%) is used in iron and steel smelting, aerospace combustion support, etc. It is produced by separating the atmosphere through the cryogenic distillation process, featuring high purity, stable supply, safety and reliability.

High-purity inert gases (purity ≥99.999%), used as industrial protective gases and chemical raw materials. Produced by the air separation cryogenic distillation process with features of a mature production flow, high purity and strong stability.

High-purity inert gas (≥99.999%), used in stainless steel smelting, photovoltaic protection, etc. Produced by the air separation process, it meets purity standards, ensures stable supply, and is suitable for high-end manufacturing.

It is classified into industrial grade and food grade, and is used in beverages, dry ice, and oil extraction. Produced through self-patented waste gas recovery technology, the food-grade purity reaches ≥99.99%, ensuring environmental sustainability and consistent quality.

Food-grade CO₂ is processed into 3mm granular, columnar, or block dry ice, which is used for cold chain preservation and industrial cleaning. With self-supplied raw materials, it ensures safety and reliability while meeting diverse application needs.
