Food Storage

Liquid Nitrogen (LIN) is both highly stable and highly available for CO2 food cooling applications.

Suitable for most food types, from meat and seafood products to poultry, vegetables and baked goods, cryogenic cooling with nitrogen is fast, efficient and maintains food quality.


Nitrogen-filled reflow soldering and wave soldering, using nitrogen can effectively inhibit the oxidation of solder, improve the soldering wettability, accelerate the wetting speed, reduce the generation of solder balls, avoid bridging, reduce soldering defects, and obtain better soldering quality. Use nitrogen with a purity greater than 99.99 or 99.9%.


Tire manufacturing and tire inflation

Nitrogen in tires is becoming a popular alternative to standard compressed air. Nitrogen is all around us. It's in the air we breathe, and nitrogen has many advantages over oxygen/compressed air. Inflating tires with nitrogen can improve vehicle handling, fuel efficiency and tire life through better tire pressure maintenance, fuel economy, and cooler tire operating temperatures.


In the electronics industry, nitrogen plays a big role. The packaging, sintering, annealing, reduction and storage of electronic products are all inseparable from nitrogen. The electronics industry generally has high requirements for nitrogen, usually 99.99% or 99.999% pure nitrogen. Atmospheric protection, cleaning and chemical recovery of semiconductor and integrated circuit manufacturing processes in the electronics industry are all inseparable from nitrogen.


3D printing

Nitrogen is an economical, readily available chemically stable gas that is the key to gas solutions in metal 3D printing. Metal 3D printing devices often require a sealed reaction chamber, both to prevent leakage of toxic and harmful by-products, and to eliminate the effects of the presence of oxygen on the material.


In the chemical industry, nitrogen is widely used in chemical raw material gas, pipeline purging, atmosphere replacement, protective atmosphere, product transportation, etc. In the oil industry, it can improve oil processing and refining processes, oil storage and pressurization of oil and gas field wells,and more.
