The need for cooling capacity is increasing globally. An expanding population and an ever-growing dependence on data increases the need for process cooling, centralized space cooling, and data center cooling. Meanwhile, in many places, water scarcity is a massive issue.
Despite their similar exterior appearance, cooling towers and closed-circuit coolers are very different pieces of equipment with distinct advantages and limitations. This is especially true when determining which option is best suited for a specific cooling application.
As the data center industry develops and managers implement innovative new approaches that drive energy efficiency, taking action to reduce environmental impact often also leads to cost savings.

As data centers are huge consumers of power, and electricity is the main cost of their operation, adding renewable energy to an energy-efficient infrastructure is the key for data center sustainability.
Rather than wax on about all the many things that impacted our industry this year and will shape it going into 2023, let’s focus on a big one: the shrinking availability of water.
Mission critical data center operations typically require significant amounts of water and energy for cooling, and hyperscale server rack power density is expected to double as soon as 2023.
It’s a common question during the early design phase of large mechanical systems: “Is open-loop or closed-loop cooling equipment better suited for this project?”
As water becomes increasingly scarce, more attention will continue to be aimed at developing less-water intensive cooling alternatives for data centers.
While the PUE metric clearly defines the measurement process for facility efficiency (thanks to The Green Grid!), it represents only a portion of sustainability in the overall data center eco-structure.
