Cryogenic ASU

In the field of industrial gas separation, Cryogenic ASU has become an industry benchmark for the production of ultra-high purity oxygen, nitrogen and argon with its outstanding purification capabilities. Through deep freezing technology, Cryogenic ASU cools compressed air to extremely low temperatures, using the boiling point difference of each component to achieve accurate separation, with a maximum purity of 99.999%.

Why choose Cryogenic ASU?

Unlike membrane separation or pressure-switching adsorption (PSA) technology, Cryogenic ASU can meet areas with extremely high requirements for gas purity, such as steel smelting, electronic semiconductors and medical oxygen supply. Its core advantages are:

• High efficiency and energy saving: Optimized low-temperature liquefaction process significantly reduces energy consumption
• Large-scale production: a single set of equipment can achieve a supply of 10,000 tons of gas
• Future compatibility: It can be adapted to emerging technologies such as green hydrogen preparation and carbon capture

Technological breakthrough: Three innovation dimensions of Cryogenic ASU

1. Energy efficiency revolution

The latest generation of Cryogenic ASU adopts a three-stage expansion refrigeration cycle and is paired with an AI-driven dynamic energy consumption management system, which saves more than 30% energy compared to traditional equipment. Its unique "low-temperature cooling" technology can effectively curb the load fluctuations of the power grid and achieve true green production.

2. Material upgrade

• Adopt aerospace-grade stainless steel inner liner and vacuum multi-layer thermal insulation structure
• Revolutionary graphene-enhanced molecular sieve adsorbent
• Zero leakage magnetic drive cryogenic pump

3. Intelligent operation and maintenance

Build a virtual factory through digital twin technology to predict device status in real time. The mobile monitoring system allows managers to grasp 18 key parameters such as oxygen purity and liquid nitrogen production at any time.

Industry empowerment cases

• In the field of new energy: Provide 99.99% nitrogen protection for hydrogen liquefaction plants
• In the semiconductor industry: Ensure a stable supply of electronic-grade ultra-high-purity gases
• In the medical system: build an all-weather medical oxygen emergency support network

Cryogenic ASU is not only the cornerstone equipment for industrial production, but also an important technical carrier for achieving the "dual carbon" goal. With the launch of the fourth-generation intelligent Cryogenic ASU, the gas separation industry is ushering in an unprecedented revolution in efficiency.
