Liquid cooling firm LiquidStack has secured a large-scale order from a major data center customer.

The company this week announced a 300MW order of Coolant Distribution Unit (CDU) capacity from an unnamed “major US-based data center operator.”

The order covers multiple undisclosed sites and will support “AI-ready data center deployments.”

The customer is described as a “long-established operator with a growing portfolio of AI-ready facilities across the United States.”

“Orders of this size signal a clear inflection point for liquid cooling,” said Joe Capes, CEO of LiquidStack. “Operators are committing to liquid cooling as core infrastructure for AI, and LiquidStack is uniquely positioned to support that transition at scale.”

Founded as Allied Control in 2013, LiquidStack offers both single and two-phase liquid cooling solutions. It also offers prefabricated modular cooling solutions for Edge applications.

The company launched a 1MW CDU for direct-to-chip liquid cooling in 2024, and last year announced a modular single-phase CDU reportedly scalable up to 10MW.
