The Hidden Infrastructure Race: Why Data Center Cooling Is Becoming a Billion-Dollar Business
Data center cooling has quietly become one of the fastest-growing segments in industrial infrastructure, accounting for more than half of sales growth for major equipment manufacturers as artificial intelligence (AI) adoption accelerates worldwide. The explosive demand for AI computing power is forcing companies to rethink how they keep massive server farms cool, creating ripple effects across insurance, investment, and energy sectors that few outside the industry are tracking.
Why Is Data Center Cooling Suddenly So Critical?
The surge in AI infrastructure is generating unprecedented heat loads. New-generation AI processors produce far more thermal energy than traditional computing equipment, pushing cooling systems to their limits. Belimo, a Swiss manufacturer of heating, ventilation, and air conditioning (HVAC) control systems, reported that data center cooling solutions accounted for slightly more than half of the company's absolute sales growth in the first half of 2026, with overall sales climbing 29.6% year-over-year. This wasn't a one-region phenomenon; the demand appeared across all geographic markets, though it was particularly pronounced in the Americas and Asia Pacific.
The Americas region saw especially strong momentum, with data center verticals driving 35.1% local currency sales growth. Despite equipment supply chain constraints and power availability concerns, demand for new AI data centers remained robust. Companies increasingly adopted advanced liquid cooling technologies, particularly direct-to-chip cooling systems that pump coolant directly onto processors to manage extreme heat densities.
What Makes Direct-to-Chip Cooling So Important for AI?
Traditional air-cooling methods are hitting physical limits as AI chips become more powerful and densely packed. Direct-to-chip liquid cooling represents a fundamental shift in how data centers manage thermal loads. Belimo's advanced control valve technology became the solution of choice for leading chip manufacturers and hyperscalers, companies that operate massive cloud computing infrastructure at global scale. The company's Energy Valve, sensors, and damper actuators are now standard components in these systems, with control valve sales jumping 48.3% in local currencies during the first half of 2026.
Asia Pacific demonstrated the strongest growth trajectory, with sales increasing 58.0% in local currencies. Customers showed strong interest in Belimo's newly opened Data Center Experience Center in Singapore, which showcases direct-to-chip liquid cooling applications. This facility serves as a physical demonstration of how cooling technology integrates with broader data center infrastructure.
How Are Global Investors Positioning for AI Infrastructure Growth?
Investment firms are recognizing that AI infrastructure extends far beyond just chips and servers. The ecosystem includes power generation, electricity networks, cooling systems, and supporting infrastructure. HSBC's investment outlook identifies AI, energy, and security as three forces likely to shape capital deployment over the coming years. The bank's analysis suggests that rising electricity demand from AI, electrification, and advanced manufacturing will require substantial investment in power generation and electricity networks.
"Global investment demand in sectors like renewables, nuclear power, grids and batteries will be enormous, and the funding needs will be huge," said Desmond Kuang, chief investment officer for Asia at HSBC Private Bank and Premier Wealth.

The scale of required investment is staggering. A Goldman Sachs Global Institute scenario analysis estimates around $7.6 trillion in cumulative AI capital expenditure between 2026 and 2031. The five largest hyperscalers alone are projected to spend $750 billion in 2026 on infrastructure expansion.
What Risks Are Insurers Facing in This New Era?
As data center investments accelerate globally, insurance companies face unprecedented underwriting challenges. Swiss Re estimates that cumulative global data center property and casualty insurance premiums could reach $90 billion between 2024 and 2030, while up to $400 billion in capital could be required to support these projects. However, the complexity of these facilities creates significant risk management hurdles.
Data centers have critical interdependencies that traditional insurance models struggle to address. These include:
- Electricity Supply Risk: Data centers depend on uninterrupted power; any grid failure or supply disruption can halt operations and trigger massive business interruption losses.
- Cooling System Failures: Advanced liquid cooling systems are sophisticated and interconnected; a single component failure can cascade into facility-wide shutdowns within minutes.
- Geographic Concentration: Many data centers cluster in specific regions, creating accumulation risks where a single natural disaster could damage multiple facilities simultaneously.
- Cyber and Operational Technology Exposure: Modern data centers rely on increasingly connected operational systems, expanding vulnerability to both physical and digital threats.
"Traditional underwriting is no longer sufficient; you now need to understand the engineering design, the operational resilience and the accumulation risk," said Ivan Gonzalez, CEO of Swiss Re Corporate Solutions.

Gonzalez noted that some data center projects carry asset values around $20 billion, with sizeable business interruption exposure that can exceed the primary asset value. In developed markets like Southeast Asia, traditional insurance placement may be available, but capacity and scope limitations often emerge. This has driven demand for alternative risk transfer solutions, including parametric insurance and specialized coverage structures.
Where Is Africa Emerging as a New Data Center Hub?
Africa represents a frontier market for data center expansion, driven by investor appetite for geographic diversification and lower natural catastrophe concentration than established markets. McKinsey and Company projects that demand for Africa-based data center capacity will grow from approximately 0.4 gigawatts (GW) in 2025 to as much as 2.2 GW by 2030, requiring up to $20 billion in new investment. Several major projects were announced or advancing by mid-July 2026, including a $400 million data center expansion in Egypt, a $400 million 20-megawatt (MW) facility powered by a 100 MW on-site gas plant in Nigeria, and Equinix's $467.9 million investment program to add 160 MW of capacity across South Africa.
South Africa faces particular electricity demands from this buildout. The African Energy Chamber estimates that South African data centers will consume more than 16 terawatt-hours (TWh) of electricity annually by 2030, equivalent to approximately 6.5% of the country's projected electricity consumption that year. This concentration of demand creates both opportunity and risk for local power utilities and insurers.
The continent's abundant solar and wind resources offer potential for sustainable power solutions. However, the infrastructure upgrades required for reliable, scalable power delivery remain a critical bottleneck. Many proposed data centers require not only electrical capacity but also water infrastructure improvements for cooling systems, creating additional investment and risk management complexity.
What Does This Mean for Equipment Manufacturers and Investors?
The data center cooling boom represents a structural shift in industrial demand, not a temporary spike. Belimo's performance demonstrates that companies positioned in the cooling and control systems space are capturing significant market share as AI infrastructure scales. The company's 29.6% year-over-year sales growth, driven substantially by data center demand, suggests this trend will persist as long as AI adoption accelerates.
For investors, the opportunity extends across multiple layers of the infrastructure stack. Beyond cooling equipment manufacturers, opportunities exist in power generation, grid modernization, renewable energy, battery storage, and specialized insurance products. The interconnected nature of these systems means that weakness in any single component can cascade through the entire ecosystem, creating both risk and opportunity for sophisticated investors.
As the AI infrastructure buildout continues through the remainder of 2026 and beyond, the unsexy but essential business of keeping data centers cool will remain a critical driver of growth, investment, and risk management innovation across the global economy.
