The data center thermal management market has seen extraordinary growth in response to the unprecedented levels of power and cooling needed to support high performance computing and AI. According to research firm Dell’Oro Group, data center liquid cooling will enter the mainstream this year, with a market value projected to surge to $15 billion over the next five years.
“Every industry has its eye on AI, and data centers are now looking to liquid cooling to enable hyperscalers and global enterprises to capitalize on the vast potential of AI technologies,” LiquidStack board chair Wahid Nawabi said in a statement. “As a liquid cooling provider that not only offers both hybrid and holistic cooling approaches, but also has a proven track record of deploying these technologies on a very large scale, LiquidStack is well-positioned to be at the leading edge of a new era of data center infrastructure.”
LiquidStack offers a comprehensive portfolio of advanced, powerful, and energy-efficient liquid cooling products and services.

Per the company, its family of solutions includes:
Direct-to-Chip Cooling: LiquidStack’s universally compatible coolant distribution unit (CDU) product line is built for advanced computing applications such as generative AI and HPC. The CDW-1MW is the inaugural product in the line, and is full-load tested and ETL, CSA and CE certified, with 1,350kW of cooling capacity.
Single-Phase Immersion Cooling: LiquidStack’s single-phase immersion cooling solution offers advanced flow technology to optimize heat transfer and rejection, with system dimensions suitable for data center retrofit and modular containers.
Two-Phase Immersion Cooling: Described by the company as “the most advanced cooling technology in the market,” the space-saving two phase immersion solution enhances data center efficiency and features superior thermal management with minimal energy consumption, ideal for high-density server environments.
Micro Data Centers: The MicroModular and MacroModular turnkey data centers offer 250kW of liquid cooling in a small modular container and 1.5MW of liquid cooling in a full modular container, suitable for local and regional edge, and 5G use cases.
Full Lifecycle Services: Services include expert installation, proactive maintenance, and continuous support.
All LiquidStack products are designed and manufactured in the company’s Carrollton, Texas, facility, which opened in March 2024. The company is planning to expand its direct-to-chip CDU roadmap to align with the thermal trajectory of GPU and CPU chips. Additionally, LiquidStack will continue to invest in its two phase and single phase solutions to support use cases in which holistic liquid cooling is more suitable than hybrid approaches.LiquidStack is a leader in liquid cooling for information technology hardware, telecommunications, and blockchain systems.
LiquidStack said it pioneered the world’s highest density, most efficient, and sustainable liquid cooling solution in 2012, and added that its advanced liquid cooling solutions continue to serve as the backbone for highly scalable and environmentally safe hyperscale, colocation, enterprise, edge, and blockchain data centers.
The company said its universal direct-to-chip CDUs, DataTank, EdgeTank, CryptoTank, MicroModular and MacroModular systems and services are enabling real-time advancement of computing and communications “while supporting a sustainable planet.”
