What is the LiquidStack CDU-1MW?
The CDU-1MW is LiquidStack's high-capacity coolant distribution unit (CDU) for direct-to-chip and hybrid liquid-cooled data centers. A CDU normally pumps and conditions the technology coolant loop while a heat exchanger passes its heat to facility water without mixing the two fluids. LiquidStack's announcement says a United States operator ordered 300 MW of aggregate CDU-1MW capacity for several sites. That order is evidence of planned deployment scale, not evidence that one unit removes exactly 1 MW under every duty condition or that the full order is operating. The release describes precise thermal control, high availability, and simplified operations, but it does not publish the temperatures, flows, pressure, electrical use, dimensions, materials, filtration, redundancy scheme, or control protocols behind those terms. Treat “1MW” as the product class until a project submittal states capacity at the site's primary and secondary supply temperatures, return temperatures, coolant mix, and allowable pressure drop. Confirm whether the unit can serve the chosen cold plates and rear-door equipment, which water-quality standard applies, and how its connections match headers and manifolds. Procurement should also ask for pump and heat-exchanger curves, turndown, heat loss, sound, leak detection, alarms, service clearances, and factory test records. Define what remains online after one pump, drive, sensor, power feed, or controller fails. The source does not identify the customer or server platforms, so it cannot establish compatibility with a particular rack design.
