Application
The Vertiv Liebert XDU450 is the 450 kW member of the Liebert XDU coolant distribution unit family, delivering filtered, temperature-controlled secondary-loop coolant to direct-to-chip cold plates or rack rear-door heat exchangers in high-density AI halls. Redundant pumps and dual power feeds keep the loop running through a single failure, and the onboard touch screen exposes supply/return temperatures and leak alarms. QS Compute supplies XDU450 CDUs and the surrounding liquid-cooling loop: quick-disconnects, cold plates, manifolds and hoses.
