Daikin Applied Americas has announced the acquisition of Chilldyne, an experienced leader in negative pressure liquid cooling systems for high-performance and AI data centres.
The acquisition complements Daikin Applied's existing data centre solutions portfolio, furthering its commitment to sustainable, high-efficiency cooling technologies and bolstering its mission to deliver end-to-end cooling solutions that meet the mission-critical demands of hyperscale and next-generation AI data centres.
Daikin Applied Americas COO, Yu Nishiwaki, said by acquiring Chilldyne, the company is poised to deliver a comprehensive suite of data centre cooling solutions that address the evolving needs of customers and sets a new standard for performance and uptime.
"Chilldyne's negative pressure technology offers cost and uptime advantages over traditional positive pressure systems, positioning our business as a leader in the high-performance data center cooling space."
Chilldyne's patented liquid cooling distribution unit (CDU) technology uses a negative pressure system that delivers chip-level cooling while mitigating the risk of damaging leaks that plague traditional liquid cooling solutions. The system safely and efficiently removes heat directly from the processors through cold plates, ensuring systems can run the latest GPUs while preventing leaks, lowering costs, and protecting valuable assets.
Additionally, Chilldyne's solutions deliver multiple benefits to data-intensive environments, including simplified installation, lower hardware costs and downtime risks, and enhanced energy efficiency. The technology is particularly well-suited for high-performance computing and AI applications, where high heat loads make liquid cooling a necessity.
Joining Daikin Applied allows Chilldyne to rapidly scale its second-generation liquid cooling ecosystem to enable global data centre adoption," according to Chilldyne CEO, Dr. Steve Harrington.
“We look forward to working together to widely deploy our resilient system to ease the transition to a liquid-cooled future."
Daikin Applied's acquisition of Chilldyne marks a pivotal step in its broader strategy to deliver a comprehensive ecosystem of cooling solutions for hyperscale data centres. Chilldyne and DDC Solutions (acquired by Daikin Applied in August 2025) bring a previously proven integration between Chilldyne's liquid cooling technology and DDC's modular high-density cooling cabinets.
Together, they've enabled efficient and reliable cooling for high-density rack environments, showcasing a seamless integration that now becomes a cornerstone of Daikin Applied's expanded portfolio.
Chilldyne's team, led by Harrington, will join Daikin Applied, contributing to the organization's growing centre of excellence dedicated to advancing data centre-focused technologies.
