Madrone

Madrone provides cooling for data centers by supplying 20°C water, enabling up to 30% less power and water use than traditional chillers, and operating outside the data center to maximize compute density without installing a conventional chiller.

Madrone delivers cool water at 20°C to data centers using a thermodynamic process that avoids conventional mechanical chillers. It reduces water and electricity consumption by about 30% compared to chiller-based systems and eliminates the need for wet bulb-based cooling. The solution enables retrofit and new builds, supports high-density compute to prevent thermal throttling, and is positioned to scale for hyperscale deployments while fitting into existing facility shells and external cooling configurations.

Who it’s for: Data center operators and facility owners seeking lower cooling power and water usage, higher compute density, and retrofit or hyperscale deployment options.
