A patented data center cooling concept developed by Daikin Applied Europe and CTS Group achieves Power Usage Effectiveness ratings below 1.20 in Middle Eastern operating conditions.
The joint architecture combines Daikin chiller systems and application controls with CTS Group prefabricated modular engineering. The companies designed the setup to lower electricity costs and free up electrical capacity for compute hardware.
Projected Energy Efficiency Benchmarks
According to technical specifications released by both companies, the concept supports projected PUE levels as low as 1.09 in Nordic climates. Testing confirms PUE remains below 1.20 under assessed Middle Eastern ambient conditions.
Actual efficiency varies based on climate conditions, system configurations, and the share of IT load handled through liquid cooling. The design uses free-cooling methods and optimized facility water circulation to minimize non-IT electrical draw across varying seasonal temperatures.
Addressing Thermal Fluctuations in AI Servers
Large language model training creates rapid heat spikes in server racks. These thermal shifts place heavy operational demands on standard chiller equipment, which must maintain stable water supply temperatures for liquid loops.
CTS Group and Daikin integrated buffer pipe technology with specialized water systems to manage sudden thermal changes. Factory testing demonstrated stable water delivery to Coolant Distribution Units during simulated artificial intelligence workloads and brief electrical interruptions, ensuring continuous thermal regulation.
Optimizing Capital and Operational Costs
Lower energy consumption in cooling infrastructure directly reduces ongoing operating expenditures. Moreover, reducing auxiliary power demand allows operators to allocate a larger share of facility grid capacity directly to revenue-generating server hardware, improving overall economy metrics.
This efficiency can also reduce initial capital expenditure by decreasing the scale of electrical infrastructure needed per megawatt of compute deployment, enabling operators to streamline substation connections and power distribution systems.
Prefabricated Modular Architecture
CTS Group manufactures complete, factory-tested cooling skids at its production facilities. These skids integrate Daikin chillers, coolant distribution units, and core mechanical components prior to site delivery.
By assembling and verifying mechanical modules off-site, project teams can minimize on-site civil works, reduce field installation errors, and expedite commissioning schedules for newly constructed facilities.
The modular approach shortens deployment timelines while maintaining consistent quality standards. The collaboration began in 2023, combining Swiss modular engineering with Italian chiller manufacturing capabilities to support scalable data infrastructure expansion across global markets.
