5 Fastest-Growing Data Center Cooling Stocks to Invest in Right Now

3. nVent Electric plc (NYSE:NVT)

nVent Electric plc (NYSE:NVT) is one of the fastest-growing data center cooling stocks to invest in right now. The company’s latest data center cooling angle came on June 1, 2026, when Siemens announced a reference architecture for NVIDIA AI data centers that incorporated nVent-aligned design considerations. The reference design targets NVIDIA DSX Vera Rubin NVL72 deployments, where rising rack densities are pushing infrastructure requirements beyond traditional air-cooled setups and toward integrated power and cooling architectures.

nVent’s role in this shift is built around liquid cooling and high-density rack infrastructure. The company has said it has deployed more than two gigawatts of liquid cooling capacity globally, while its data center portfolio includes coolant distribution units, liquid-to-air heat rejection units, rear-door heat exchangers, rack manifolds, and high-density power distribution. In November 2025, nVent also unveiled modular row-based CDUs, rack-based CDUs, technology cooling system manifolds, and updated racks designed to support next-generation AI chips. The demand is already showing up financially, as nVent’s first-quarter 2026 sales rose 53% year over year, with Systems Protection sales up 76%.

nVent Electric plc (NYSE:NVT) provides electrical connection and protection solutions, including systems protection, enclosures, liquid cooling, racks, power distribution, and electrical connection products for data centers, utilities, industrial, and commercial markets.
