Who makes leak detection, flow & pressure sensing for AI data centers

Because a leak in a direct-to-chip loop sits centimeters from live electronics, leak detection is a safety-critical layer that runs alongside the physical plumbing described elsewhere in this section: cable- or rope-style sensors laid along cold plates and manifolds detect moisture at the point of a leak, while flow and pressure sensors at the CDU and manifold level watch for the drop in flow or pressure that signals a blockage or a failed connection. These feed into the rack/row cooling controls (5.11) that can shut off flow to an affected branch or alert facility staff before a small leak becomes tray-level or rack-level damage. As liquid cooling scaled from pilot deployments to the default configuration for AI racks, the number of monitored points per rack rose with the number of quick disconnects and manifold branches it has to cover. Investors should watch this as a volume-driven category tied to liquid-cooled rack count rather than a design-differentiated one, though reliability and false-alarm rates differentiate vendors competing for hyperscale-scale deployments.
