Today, DEAR Air Separation held the kick-off meeting for the Phase III cold box and installation contract of Chongqing Tonghui Kesheng Gas Co., Ltd.'s 18,000-ton/year electronic-grade nitrous oxide project. Department heads from core functions including sales, design, supply, finance, production, and installation attended.

This contract covers the full lifecycle services for the nitrous oxide unit cold box, from design and manufacturing to installation and commissioning. Delivery must be completed according to schedule post-contract effectiveness, requiring a single-pass performance test. As critical equipment in the electronic specialty gases field, the stability and precision of the cold box directly impact end-product quality. The project's successful outcome will stand as a significant performance benchmark for DEAR Air Separation in the high-end gas equipment sector.

The meeting established the "Three Guarantees" as the core principle for project advancement:
1. Guaranteed Schedule Milestones: Production and supply departments must collaboratively optimize production scheduling, with the installation team conducting early site surveys.
2. Guaranteed Zero-Defect Quality: The design phase must strictly adhere to international standards, with the quality inspection system covering the entire chain from raw material intake to finished product shipment.
3. Guaranteed Safe and Civilized Construction: 100% of on-site personnel must implement safety protection measures, establishing a model green construction site.

Additionally, the sales manager will serve as the primary client contact, implementing a "Daily Report + Weekly Meeting" mechanism to synchronize critical information—including payment processing, delivery acceptance, and issue resolution—in real time, ensuring efficient and seamless communication.
