Fan wall vs CRAC is the question most data hall designs answer out of habit, copying the last build instead of the current load.

Get the loop volume wrong and the chiller short-cycles, because many compressors are limited to roughly three to six starts per hour. This blog walks you through when a chilled water system actually needs a buffer tank, how to […]
Thermal energy storage data centre projects have shifted from nice-to-have to budget lever, now that cooling can swallow 30 to 40 percent of a facility’s electricity. This blog walks you through how a chilled water storage system moves that load off-peak to cut cost, and how the same tank buys 15 to 30 minutes of […]
