HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Recently, the 1600Nm³/h deep cryogenic air separation high-nitrogen equipment specially tailored by Nuzhuo for CATL, a global lithium battery leader, has completed the key connection. This successful connection not only serves as a significant demonstration of Nuzhuo Group’s strength in the high-end equipment field of new energy, but also promotes the high-quality development of the lithium battery industry through the deep cryogenic air separation technology.

CATL, as the absolute leader in the consumer lithium battery sector, has always maintained the highest standards in its technical routes, quality criteria, and supply chain choices. Its selection of key supporting equipment, especially in the high-purity nitrogen supply system that is crucial for battery consistency, safety, and production yield, is extremely demanding.

The fact that Nuzhuo was able to stand out from numerous competitors and successfully deliver and connect this key equipment to CATL fully demonstrates that Nuzhuo’s technological leadership, product reliability and high-end project execution capabilities in the field of cryogenic air separation have been fully recognized by the industry’s top players.

The purity of nitrogen is the lifeline. Nuzhuo has ensured the ultimate stability of nitrogen purity through multiple core technologies. Firstly, Nuzhuo employs deep freezing and distillation tower technology. The core of the equipment lies in the principle that different components in the air have different boiling points. At extremely low temperatures, the air is liquefied and then separated through a specially designed high-efficiency structured packing distillation tower. Nuzhuo has optimized the internal logistics distribution and heat and mass exchange efficiency of the tower, enabling more thorough separation of nitrogen and oxygen. This ensures the production of high-purity nitrogen from the very beginning;Secondly, Nuzhuo has utilized the dual protective effect of imported molecular sieves. Nuzhuo employs a two-stage adsorption system of imported high-end molecular sieves. Firstly, it deeply removes moisture, carbon dioxide, and hydrocarbons and other impurities from the air to prevent these impurities from freezing and blocking the equipment at low temperatures. It also further eliminates trace harmful gases, providing “clean air” for the subsequent deep cryogenic distillation, which is a crucial pre-condition for ensuring the purity of the final product ; Furthermore, Nuzhuo has developed an online monitoring and automatic adjustment system. The system is equipped with high-precision online purity monitoring devices such as laser analyzers, which provide real-time data feedback and are linked with the DCS control system. This enables fine-tuning of the distillation process, ensuring that the nitrogen purity remains consistently at the highest standard stipulated in the protocol under any load fluctuations.

The success of this cooperation has a profound impact on the lithium battery and new energy industries. It provides reliable, economical and pure gas support for the capacity expansion of CATL, helping it improve the consistency and safety of its high-end battery products.

More importantly, by delivering such benchmark projects, Nuzhuo has set a high standard model for the application of deep cryogenic air separation equipment in the field of new energy, accelerating the evolution of lithium battery manufacturing towards greater refinement and higher quality, and providing a solid industrial infrastructure support for the implementation of China’s new energy strategy.

Nuzhuo will continue to be driven by technological innovation, deeply focusing on the field of gas separation, and providing safer, more efficient and smarter gas solutions for more customers in high-end manufacturing industries such as new energy and semiconductors.
