Liquid oxygen for metal smelting is a core combustion-supporting gas for the iron and steel, non-ferrous metallurgy and other industries.

Gases for the food low-temperature grinding industry are a critical supporting component in deep food processing. Taking food-grade nitrogen as the core inert gas, it forms a gas protection barrier in the low-temperature grinding process by virtue of its oxygen-proof, temperature insulation and control properties.

Gases for water treatment are critical supporting elements in municipal sewage treatment, industrial wastewater purification, and pure water preparation.

Liquid nitrogen for food flash freezing is a game-changing "freshness-locking tool" in the food processing industry. Leveraging its ultra-low temperature of -196℃, it achieves rapid freezing of ingredients, instantly locking in cellular moisture and nutrients while solving the pain points of taste loss and nutritional degradation associated with traditional freezing methods.

Liquid oxygen for aquaculture is a "high-efficiency oxygen supply tool" for high-density aquaculture. By precisely aerating after liquid oxygen vaporization, it can quickly increase dissolved oxygen in water, solving the pain points of low efficiency and uneven coverage of traditional aeration methods.

Nitrogen pipeline purging is a crucial process following the installation and maintenance of industrial pipelines. Leveraging nitrogen's inert, dry, and residue-free properties, it removes impurities such as welding slag, rust, and dust from pipelines, preventing impurity contamination of transported media, equipment wear, or blockage failures.
