LiquidStack, a data centre liquid cooling provider, said it has secured an order for 300MW of coolant distribution unit capacity (CDU) from a large US data centre operator, signalling growing demand for liquid cooling as operators build out AI-ready facilities.

The multi-site deal centres on LiquidStack’s CDU 1MW units, which the company said are designed for faster deployment and higher performance in high-density environments. 

LiquidStack did not name the customer, describing it as an established operator expanding a US portfolio of AI-ready sites.

The company said its manufacturing and delivery capacity will allow it to supply the equipment on an accelerated timeline across multiple locations. 

“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.”

LiquidStack said its CDUs are built to work with direct-to-chip and hybrid liquid cooling setups, offering tighter thermal management, redundancy, and simpler day-to-day operations. 

The company also said that it supports deployments globally, backed by in-house design, manufacturing, rollout, and lifecycle services.

It added that demand has been rising, pointing to its placement on NVIDIA’s recommended vendor list for CDUs, a manufacturing expansion in Carrollton, Texas, and broader uptake of its CDU platforms for AI and accelerated computing workloads.

LiquidStack provides liquid cooling systems for data centres and other computing infrastructure. The company, founded in 2012, supplies direct to chip CDUs and modular cooling products used across hyperscale, colocation, enterprise, edge, and blockchain facilities.
