Efficient cooling of server racks (colocation) is crucial for data centres in order to ensure the performance and longevity of the hardware. Liquid-cooled systems are becoming increasingly important in this respect, and as a result, German organisation Poppe + Potthoff Maschinenbau (PPM) is developing test benches to examine and optimise the quality of cooling components and systems.
According to current forecasts by the International Energy Agency (IEA), data centres will consume more than 800 terawatt hours of energy worldwide by 2026 – more than twice as much as in 2022. Liquid cooling systems help to improve power usage effectiveness (PUE). They are up to 40% more efficient than conventional air cooling and make a significant contribution to reducing energy consumption and costs.
