Zhongxin Chuangwei provides clock synchronization equipment to Lutianhua (Group) Co., Ltd.

Recently, Lutianhua (Group) Co., Ltd. issued a tender for time servers. Beijing Zhongxin Chuang promptly collaborated to develop a detailed proposal and recommended its independently developed and manufactured DNTS‑9HG time server as the bid‑winning product. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, ultimately securing the contract for the time‑server project from Lutianhua (Group) Co., Ltd.

Lutianhua Group, leveraging the abundant resource advantages of the “Land of Abundance,” has established a production base that uses natural gas to manufacture agricultural fertilizers and vegetable and animal oils to produce industrial products. Lubricant chemicals It possesses large-scale production capacity. Currently, it has established an integrated production capability of 800,000 tons per year of synthetic ammonia, 1.24 million tons of urea, 50,000 tons of nitric acid, 110,000 tons of ammonium nitrate, and 30,000 tons of oleochemicals. It has grown into a super‑large chemical enterprise that integrates production, research, design, manufacturing, construction, installation, trade, and services, pursuing diversified operations and multi‑faceted development, thereby making enduring contributions to the advancement of China’s chemical industry. It has been listed among the 520 state‑owned large enterprises receiving key national support and has ranked among China’s top 500 industrial enterprises and those with the best economic performance.

Lutianhua (Group) Co., Ltd. conducted an in-depth evaluation of the DNTS-9HG time server independently developed by Zhongxin Chuang, and the results exceeded all specified performance parameters. The company expressed high satisfaction with both the product’s quality and our after-sales service, proceeding to place a successful order and put the system into operation.

The DNTS-9HG network time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is an intelligent, high-precision NTP network time server. It obtains standard time information from the GPS navigation and positioning satellite system and provides standard time services over the network via NTP/SNTP or other network protocols. Devices in the network that require time synchronization—such as personal computers, servers, and controllers—can synchronize with international standard time. When using a GNSS satellite receiver, users can define priority levels and configure single-receiver/dual-receiver or single-antenna/dual-antenna setups; each receiver can be set to operate in standalone or combined timing modes. If both receivers and other available time sources lose signal, the DNTS-9HG relies on its built-in temperature-compensated crystal oscillator for holdover and continues to provide uninterrupted time services.

In addition to serving as a primary‑level network time‑synchronization device, the DNTS‑9HG can also function as a secondary‑level time server, enabling more effective time synchronization in large‑scale network environments. It provides precise standard time signals for systems such as distributed networks, computer security systems, file management systems, e‑commerce platforms, online B2B systems, and cloud database storage and maintenance. The DNTS‑9HG has been successfully deployed across government, finance, mobile telecommunications, public security, petroleum, power, transportation, industrial, and defense sectors. Installation and operation of the DNTS‑9HG network time server are straightforward: simply connect the satellite receiving antenna and link the Ethernet port to a network switch to achieve time synchronization across all devices on the network.
