Hangzhou Chuankong and Zhejiang Dachuan supplied the 30,000 Nm³/h Air Separation Unit to Indonesia to support the construction of Tsingshan Steel Indonesia by providing raw material gases. This steel plant is the largest Chinese-invested steel facility in Indonesia. Between 2016 and 2017, Hangzhou Chuankong delivered multiple air separation units to Indonesia, but this latest unit is the largest to date, once again demonstrating Hangzhou Chuankong and Zhejiang Dachuan's technical, manufacturing, quality, and service strengths in air separation equipment. It also reinforces the influence of “Made in China” in the Indonesian market. 

During the manufacturing process, leveraging the technical and production capabilities of SASPG Group, Hangzhou Chuankong and Zhejiang Dachuan adopted innovative design and manufacturing approaches. They modularized the integrated cold box into segments for transport, greatly improving efficiency. The on-site hoisting and positioning were perfectly aligned, ensuring project quality and laying a solid foundation for the timely and high-quality completion of the project. These efforts have been highly praised by the customer.
