ZutaCore

Overview

ZutaCore builds waterless two-phase direct-to-chip cooling: cold plates in the OmniTherm family boil refrigerant directly on the accelerator, and the loop condenses it outside the server, so no water enters the rack. The vendor states the system supports accelerators beyond 4,000 watts, reduces cooling energy by roughly 74% and removes water from the server entirely, which matters in regions where water use is a planning constraint. The underlying technology, called Two-Phase Matrix Flow Boiling, is documented on the vendor's site alongside a case study guide. The company is headquartered in San Jose, California, with a US office in Foster City, an R&D centre in Israel and offices in Europe and Taiwan.

Editorial verdict

Waterless matters when the site's water budget is the binding constraint, and that is the case this vendor argues for: no water in the server, less cooling energy, higher power per accelerator. The figures, 4,000 watts and about 74% cooling energy reduction, are vendor claims and should be checked against the plant's own numbers in a pilot, because the saving depends on what the rejected heat replaces. Two-phase systems add refrigerant handling and service requirements, so ask who maintains the loop locally and what the refrigerant's availability looks like over the asset's life. Fit is an operator adding dense AI capacity where air and water both run short.
