FAQs

Your CDU questions answered.

A coolant distribution unit (CDU) is an HVAC cooling solution for data centers. The CDU moves liquid coolant through the system so the equipment doesn’t overheat and can run safely and efficiently.

A CDU works by pumping coolant through the racks of IT equipment, where the liquid picks up heat. Then it brings the warm coolant back, removes the heat, and sends cooled liquid out again.

CDUs also monitor temperature, pressure, and flow so everything stays in the right range. Some systems use direct‑to‑chip cooling, where the coolant flows through plates that sit right on top of the chips to pull heat away more quickly.

Liquid cooling with CDUs is more efficient than air cooling, especially in hyperscale data centers. It helps save energy and keeps temperatures more stable. CDUs are also reliable, have sensors that catch issues early, can scale as cooling needs grow, and work with different types of coolants and setups.
