Universal coolant distribution for Direct-to-Chip DTC liquid cooling
LiquidStack has launched the first in a series of universal coolant distribution units (CDU) for Direct-to-Chip DTC liquid cooling.
The LiquidStack CDU-1MW is designed to be universally compatible with commercial direct-to-chip (DTC) systems in data centres to cool chips for generative AI, large language models and HPC.
As data centre adoption of liquid cooling scales, the demand for standardized, DTC-optimized CDUs has accelerated significantly. However, the availability of CDUs has been limited due to production capacity constraints, according to analyst firm Omdia. The system has been developed via direct engagement with the world’s largest data centres and chip designers and is manufactured in Texas.
The CDU supports cooling capacity up to 1,350kW, which LiquidStack says can support the latest AI processors. For example, the Nvidia Blackwell GPU will require up to 2kW of power, and the company says other CDU versions are set for launch in 2025.
“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 of LiquidStack.
“Our company has been designing, manufacturing and servicing complex liquid to liquid heat exchange systems at scale for over a decade. 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 DTC liquid cooling system is designed to effectively cool high-performance workloads while decreasing energy consumption. The universal CDU-1MW is ETL and CE certified, as well as full-load tested by a third party. It caters to hyperscalers, colocation services companies, and large-scale enterprises seeking to implement DTC solutions as they shift to hybrid cooling.
The CDU interface provides programmable logic controller (PLC) with intuitive controls and monitoring tools for easy management and oversight. It also has N+1 redundancy with hot swappable dual 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, 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.”
LiquidStack’s portfolio of liquid cooling products also includes single-phase and two-phase immersion cooling systems alongside its MacroModular and MicroModular prefabricated data centres.
The CDU-1MW is now available for order.
