The growth in artificial intelligence, gaming, edge computing and big data drives the demand on data centres. Data-intensive workloads require more compute power, increasing the energy challenge. Under these conditions and driven by pressure to improve sustainability, traditional cooling methods are inefficient and unable to meet the demand. Data centres require advanced cooling systems that can efficiently deal with the increase in power density. Immersion cooling offers data centres the ability to keep up with the increasing demand for higher power density and many other advantages such as a reduction in CO2 levels, power usage and better total cost of ownership.
