Witness the decade-long rapid development of chemical processing equipment; praise the prosperity and strength of modern China. Replies will be rewarded – discussions are welcome. ------------------------------------------- On November 6, China’s first \"passively cooled skid-mounted equipment unit\" underwent technical evaluation by the China National Machinery Industry Federation in Shaoxing, Zhejiang. This product was jointly developed by the Pipeline Bureau Design Institute and Shanghai Lüzhu Residential System Technology Co., Ltd. (abbreviated as Shanghai Lüzhu), achieving a high degree of integration, intelligence, and sustainability for pipeline valve room monitoring systems. Its main technical indicators have reached the international advanced level, filling a gap in China. A large number of monitoring valve rooms need to be installed along oil and gas pipelines; the equipment housed in these rooms has functions such as emergency shutdown of the pipelines, communication relay, and cathodic protection, and it requires stringent working conditions. Ensuring that equipment can operate properly in complex environments such as extreme cold and heat, or in situations where there is no external power supply, has always been a challenge in pipeline construction. Currently, there are only a few suppliers worldwide whose products are available for selection. In response to this situation, the Pipeline Bureau’s Design Institute, after years of research, carried out technological innovations in areas such as integrated optimization, intelligent control, and utilization of green energy. In collaboration with Shanghai Lüzhu, it developed a liquid cooling system that does not require external power, enabling passive cooling with zero energy consumption between devices. It also created \"passively cooled skid-mounted equipment rooms,\" featuring standardized and modular components that can meet the requirements of monitoring systems in areas with extreme temperatures or where no external power is available.
