Zhongxin Chuangwei provides clock synchronization equipment to Sanjiang Chemical.

Zhongxin Chuangwei provides clock synchronization equipment to Sanjiang Chemical.

Recently ， Sanjiang Chemical has issued a requirement for a time server. , Beijing Zhongxin Chuang Company is actively cooperating For users A detailed plan has been prepared, and the independently developed and manufactured products of Zhongxin Chuang have been recommended. DNTS-8 Time Server and Digital Sub-Clock As the product submitted for this tender, Zhongxin Chuang emerged victorious after a fiercely competitive bidding process, thanks to its high‑quality offerings and comprehensive after‑sales service, outshining competitors’ solutions. And out, Ultimately awarded the Sanjiang Chemical Time Synchronization Server. Project.

Sanjiang Chemical Co., Ltd. China’s largest private enterprise Ethylene oxide ( EO and AEO surfactant manufacturer and supplier. The company has now established a diversified product portfolio centered on EO, ethylene glycol (EG), and polypropylene (PP), complemented by AEO surfactants, methyl tert-butyl ether (MTBE), and C5 hydrocarbons, thereby becoming a vertically integrated chemical group with balanced risk management and strong cyclical resilience.

Sanjiang Chemical Industry Developed independently by Zhongxin Chuang DNTS-8 Time server Conduct an in-depth evaluation and arrive at the final results. All are superior to the parameter requirements. ， And Regarding our company’s product quality and after-sales service Also quite satisfied. ， Procured successfully and put into use. ！

Developed by Beijing Zhongxinchuang Technology Co., Ltd. The DNTS‑8 time server is a high‑tech, intelligent, stand‑alone clock synchronization server that operates on the NTP/SNTP protocols and delivers high‑precision time. It acquires standard time‑signal data from GPS satellites and disseminates this information across the network, enabling devices requiring time synchronization—such as computers and controllers—to align with the reference clock. When all external signals are unavailable, the DNTS‑8 relies on its built‑in temperature‑compensated crystal oscillator for holdover, achieving a holdover accuracy of up to 1 × 10⁻⁹. The DNTS‑8 transmits standard time information over TCP/IP networks and supports multiple popular time‑distribution protocols, including NTP and time/UDP; it also accommodates custom‑defined time‑broadcast packets via configurable UDP ports. The port numbers for NTP and time/UDP are fixed at 123 and 37, respectively, as specified in RFC‑123 and RFC‑37. Additionally, the DNTS‑8 supports the broadcast mode of the SNTP protocol.
