Liquid-cooled load simulation for DLC commissioning

6 Oct 2026
8 min read

Data center commissioning typically concludes with an integrated system test, using load banks in place of IT equipment to verify the performance of power and cooling infrastructure. A facility designed to support direct liquid cooling (DLC) at scale introduces changes to virtually every stage of the data center life cycle, and commissioning is no exception: a liquid-cooled data center requires new types of equipment and commissioning procedures.

Several manufacturers now offer liquid-cooled load banks for DLC commissioning (sometimes called rack emulators). Most load banks designed for this purpose were commercialized relatively recently and remain an area of ongoing development.
