Cryogenic Tank

The cryogenic air separation equipment adopts low-temperature distillation technology to achieve efficient separation by compressing, cooling and liquefaction of air, and using the boiling point differences of each component, it can simultaneously produce high-purity nitrogen, oxygen and argon. As a core storage and transportation equipment, cryogenic tank has become a key guarantee for industrial gas storage and supply with its excellent cooling performance and safety and stability. The entire system is suitable for large-scale, high-purity gas demand scenarios and is the core equipment for achieving efficient and reliable gas solutions.

Gas Purity and Production Range

Technical parameters

• Operating temperature range: -196°C (liquid nitrogen) to -183°C (liquid oxygen)
