According to DCD, HVAC company Daikin Applied Americas has acquired liquid cooling firm Chilldyne in an undisclosed deal. The acquisition gives Daikin access to Chilldyne’s patented negative pressure direct-to-chip cooling systems, which can deliver up to 300kW of cooling capacity per distribution unit. This marks Daikin’s second data center cooling acquisition this year following their purchase of DDC Solutions. Yu Nishiwaki, Daikin Applied Americas’ chief operating officer, stated the move positions the company as a leader in high-performance data center cooling. Chilldyne CEO Dr. Steve Harrington said joining Daikin will allow rapid scaling of their second-generation liquid cooling ecosystem globally.

Daikin’s cooling strategy
Here’s the thing – Daikin isn’t just dabbling in data center cooling. They’re going all in. This is their second acquisition in this space within a single year, following the DDC Solutions purchase earlier. They’re basically building what they call a “comprehensive ecosystem of cooling solutions for hyperscale data centers” through strategic acquisitions rather than organic development.
And that makes perfect sense when you think about it. The data center cooling market is exploding thanks to AI workloads and power-dense chips. Traditional air cooling just doesn’t cut it anymore for these high-performance applications. By snapping up specialized companies, Daikin can move much faster than trying to develop this expertise internally.
Why Chilldyne matters
Chilldyne brings something pretty clever to the table – negative pressure technology. Most liquid cooling systems use positive pressure, which means if there’s a leak, coolant gets pushed out. But negative pressure systems actually suck air in if there’s a breach, preventing coolant from escaping. That’s a huge advantage for data center operators who are understandably nervous about putting liquid anywhere near their expensive servers.
The company’s cooling distribution units can handle up to 300kW, which is serious business for today’s AI clusters. They’re not just selling hardware either – they’ve got the whole ecosystem including cold plates, rack manifolds, and monitoring software. Basically, they’re offering a complete solution rather than just components.
The bigger picture
So what does this tell us about where data center cooling is headed? Look, liquid cooling is no longer a niche technology for supercomputers. With AI chips pushing power densities through the roof, every major data center operator is evaluating liquid solutions. And companies like Daikin that can offer both traditional HVAC and advanced liquid cooling have a serious advantage.
This acquisition also shows how traditional HVAC giants are waking up to the data center opportunity. They’ve been cooling buildings for decades, but data centers represent a massive growth market with much higher margins. It’s a smart pivot that plays to their core strengths while positioning them for future growth.
The timing couldn’t be better either. We’re right at the inflection point where liquid cooling goes from experimental to mainstream. By acquiring Chilldyne now, Daikin gets to ride that wave rather than playing catch-up later.
