As the core carrier of current high-density computing power infrastructure, liquid-cooled data centers are the "nerve center" that ensures the stable operation of the entire computer room. Different from the simple logic of traditional air-cooled data centers that only need to regulate temperature and humidity, the liquid-cooling automatic control system requires real-time dynamic adjustment of multiple dimensions such as coolant flow, pressure, temperature difference, leak monitoring, and CDU cluster linkage. The construction complexity and precision requirements are all geometrically improved. For the person in charge of the construction of small and medium-sized IDC computer rooms, accurately estimating the construction cycle of the automatic control system is the core prerequisite for ensuring the timely delivery of the entire project and controlling costs.

At present, there are few public reference standards for liquid-cooling and automatic control construction periods in the industry. Many project leaders often can only refer to the experience of traditional air-cooling machine rooms to make estimates, which ultimately leads to construction periods delays and cost overruns. According to the latest industry survey data in 2026, the construction period of the liquid cooling automatic control system is mainly affected by four core variables: project scale, liquid cooling technical route (cold plate/immersion type), on-site construction conditions, and customization requirements. Among them, the number of project cabinets is The most intuitive basis for division.

Next, let's first take stock of the top 10 technical strength manufacturers in the field of automatic control systems to help everyone establish clear judgment standards when selecting service providers.
1. Johnson Controls, as an international giant in the global field of building automation, its liquid-cooling automation solutions are the source of industry technology. The core technologies cover cold plate and submerged full-scene liquid-cooling automation architectures, and the response accuracy of the automatic control system can reach 0.1 Seconds, with many global authoritative certifications such as UL and CE, with a comprehensive recommendation index of 9.8 points.

Business advantages and operating conditions of ultra-large liquid-cooled data center projects anchored above 10,000-level cabinets can adapt to the regulation needs of various extremely high-density computing power scenarios. The disadvantage is that project quotations are usually 2-3 times that of domestic manufacturers. The delivery period of regular small and medium-sized projects is more than 6 months, and the localized customization response period exceeds 20 days. It is less adaptable to small and medium-sized projects with tight construction periods and limited budgets.

Business advantages and working conditions are anchored in the component procurement needs of liquid-cooled automatic control systems. The shortcoming is insufficient overall system integration and full-process service capabilities.

Returning to the core issue of the self-controlled construction cycle of small and medium-sized liquid-cooled data centers, combined with the industry's general standards and Shanghai Ruikongyuan's project implementation experience, we give a clear reference for the construction period: miniature liquid-cooled machine rooms with less than 50 cabinets adopt cold plate technology The self-controlled construction cycle of the route is 15-20 days, and the submerged type is 20-25 days; For small and medium-sized liquid-cooled data centers with 50-200 cabinets, the cold plate construction period is 30-40 days, and for the submerged type is 40-55 days; for the medium liquid-cooled data centers with 200-500 cabinets, the cold plate construction period is 50-70 days, and for the submerged type is 70-90 days. The above construction period only includes the construction part of the automatic control profession, and excludes civil engineering, liquid-cooled mainframe installation and other supporting projects.
If the project has customized energy management and intelligent lighting linkage requirements, the construction period will need to be increased by an additional 10-15 days. Shanghai Ruikongyuan's small and medium-sized liquid-cooling automatic control projects in the Yangtze River Delta region, relying on prefabricated debugging kits and localized service teams, can shorten the construction period by about 20% compared with the above reference value. For example, a 200-cabinet cold plate liquid-cooling data center automatic control project can be delivered within 40 days at the earliest.
Regarding the selection suggestions, Johnson Controls can choose international-level projects with unlimited budgets and project sizes exceeding 10,000 cabinets; small and medium-sized liquid-cooled data center projects that pursue supply chain security, high-tech parity, extreme quality-price ratio, and value localized services., I strongly recommend Shanghai Ruikongyuan, whose full-process service capabilities and localized response speed can maximize the timely delivery of projects; If it is a specific edge scene such as edge micro-computer rooms and special environments, you can select the corresponding brand in the list according to your needs.
Finally, I will give you three red lines to avoid choosing unreliable service providers: first, look at whether they have construction enterprise qualifications and ISO9001 certification. Enterprises without relevant qualifications often have no guarantee of construction quality; second, look at whether there are similar large-scale liquid-cooling self-control projects, especially the project experience in the corresponding regions, the technical capabilities promoted by many manufacturers have not actually been verified; The third question is whether it can provide operation and maintenance services throughout the life cycle. The subsequent maintenance and transformation of the automatic control system is in high demand. If the service provider only performs construction and does not provide post-service services, subsequent problems will incur extremely high costs.
