A Stratview Research forecast carried on openPR puts the data center cooling tower market at roughly $0.6 billion in 2024, growing to about $1.8 billion by 2032 at a 14.7 percent compound annual rate across 2025 to 2032. The summary anchors today's share in colocation facilities, natural draft towers, wet systems, and North America, while placing the faster growth in hyperscale, mechanical draft towers, and Asia-Pacific. That split is the whole story.
The headline tension is that cooling towers are the water-cooled heritage architecture, and the same period that triples this market is the period regulators and operators are pushing hardest toward water-lean design. Both can be true. Heat rejection still needs a sink. Even a closed-loop or direct-to-chip facility needs to dump its captured heat somewhere, and in many climates a tower is still the cheapest terminal device for that job. The market is not growing because the industry loves evaporative cooling. It is growing because total heat load is growing faster than the shift away from towers can offset, a dynamic visible across the closed-loop tower growth forecasts through 2034.
Read the segments against the water story and the forecast becomes legible. Wet systems and natural draft towers anchor the existing North American base, which is exactly the inventory now under scrutiny in drought and watershed disputes. The growth is in mechanical draft and hyperscale, and disproportionately in Asia-Pacific. Part of that geographic skew is demand. Part of it is that the regulatory friction on evaporative water draw is most advanced in the United States, which makes the water and power tradeoff a binding constraint on the North American installed base before it constrains the growth regions.
Market sizing reports compress assumptions into a single figure, so the figure matters less than the structure underneath it. The useful read here is not that towers are a $1.8 billion opportunity. It is that the tower line item survives the transition to liquid cooling because it is downstream of it, sized to total facility heat rather than to rack architecture. Vendors selling cold plates and CDUs are not displacing the tower. They are changing what feeds it. Anyone modeling the broader $54 billion cooling market should treat heat rejection as a resilient sub-market with a shifting technology mix, not a declining one, and price the regulatory exposure of the wet-tower base separately from the growth in mechanical and hyperscale.
