In this article, we will take a look at the top 10 data center cooling companies to invest in.

The unprecedented data center demand driven by massive investments in AI infrastructure is well-documented. According to several research reports, the total data center infrastructure market could reach $1 trillion by 2030. Companies are already trying their best to meet this surging demand.

One example of this was visible during the discussion when Jacobs Solutions CEO Robert Pragada appeared on CNBC on November 24, 2025. He not only confirmed that demand was through the roof but also explained how the industry is operating at capacity, with future growth likely propelled by quantum and life sciences. Regarding future growth, he explained that the quantum buildout could be even larger than the AI infrastructure buildout.

“It’s the synthesis of even more complex energy usage around the next form of computing. So, think AI data centers, and then if there’s a next phase of that, it would be in quantum.”

This complex energy usage will require even better cooling than existing data centers have, keeping demand for cooling solutions high. However, Pragada did point out that investments in quantum technologies were limited to R&D at the moment, but will take over from AI when practical solutions start to emerge.

“There’s a bit of development that still needs to happen before you get to full quantum computing”.

It is clear that data center demand isn’t just a result of increasing AI usage. It is likely to continue well into the future as the next generation of technologies, especially quantum, takes over from AI at some stage.

In other news, Supermicro announced on December 9 that it expanded its Nvidia Blackwell portfolio by launching 4U and 2-OU liquid cooling systems, which capture 98% of system heat through direct-liquid-cooling technology. Developments like these prompt investors to seek out the top data center cooling companies to invest in, where our list can help.

While increasing the price target from $198 to $220, the financial services firm maintained its Buy rating on the stock. This rating was issued by the analyst Andrew Kaplowitz. The newly assigned target price represents an 11.11% upside from current levels. The upward adjustment to the target price indicates that Citigroup still sees potential in Vertiv Holdings Co. (NYSE:VRT).

Vertiv Holdings Co. (NYSE:VRT) completed its acquisition of PurgeRite on December 4th for approximately $1 billion. This acquisition aims to improve the company’s thermal management services capabilities, mainly for AI and high-density computing data centers.

9. SPX Technologies, Inc. (NYSE:SPXC)

Potential Upside: 9.14%

Number of Hedge Fund Holders: 37

On December 8, the company announced that it had entered into a definitive agreement to acquire Crawford United Corporation (OTC:CRAWA), a Cleveland-based holding company. The deal is valued at approximately $300 million. This acquisition is part of SPX Technologies’ expansion plans. As per the agreement, Crawford United will be merged with a subsidiary of SPX. With this acquisition, SPXC will expand its HVAC capabilities by incorporating the Commercial Air-Handling Equipment segment of Crawford United.

The reason for its divestiture is that this segment does not align with the firm’s long-term strategy.
