LiquidStack has launched a new coolant distribution unit (CDU) designed to be compatible with direct-to-chip (DTC) solutions.

Dubbed the CDU-1MW, the CDU is specifically designed to cater to advanced computing applications such as generative artificial intelligence (AI), large language models, and high-performance computing.

With the increase in compute-intensive workloads, many are turning to liquid cooling, with DTC proving a popular solution.

However, according to research from Omdia, the availability of CDUs is currently being limited by capacity constraints.

"With a singular focus on liquid cooling, we deliver unparalleled expertise and innovation, providing the most advanced solutions, such as the CDU-1MW, for data centers and high-performance computing environments,” said Joe Capes, CEO, LiquidStack. “Our company has been designing, manufacturing, and servicing complex liquid-to-liquid heat exchange systems at scale for over a decade."

He continued: "With the ability to deliver products anywhere in the world from our US-based manufacturing facility, and our capability to provide mission-critical service response times in all major global markets, LiquidStack has quickly taken a leadership position in the direct-to-chip liquid cooling market.”

The new CDU-1MW is ETL and CE-certified, and has up to 1,350kW of cooling capacity designed to support the latest AI chips and servers.

It also has a hot-swappable dual VSD pump operation top and bottom stainless steel piping kits, with optional temperature, pressure, flow meter, and expansion tank redundancy.

"Our exclusive commitment to liquid cooling ensures that LiquidStack products incorporate the latest advancements and best practices in cooling technology,” said Nick Schweissguth, global director of product management at LiquidStack. “The CDU-1MW is built to withstand the rigors of the highest performance environments, enabling large-scale data center operators to de-risk AI deployments via rapid integration to existing direct-to-chip systems."

Manufactured at LiquidStack's Carrollton, Texas facility, the solution is suitable for adoption by hyperscalers, colocation providers and large-scale enterprise companies. It is immediately available for order, and additional CDU products are planned for release in 2025.

Several other companies have recently released CDUs specifically for liquid cooling solutions in the last few months. Among them are Stulz and Chilldyne. In July, The Green Grid released a CDU sizing tool to help companies pick the right cooling units for their data centers.
