# Vertiv Expands Across AI Data-Center Thermal Chain > Source: > Published: 2026-06-17 19:54:53.059281+00:00 # Vertiv Expands Across AI Data-Center Thermal Chain Vertiv Holdings (NYSE: VRT), a critical digital infrastructure supplier, completed the acquisition of Italian cooling specialist ThermoKey on June 12, 2026, adding dry coolers and microchannel heat-exchange technology to its thermal management portfolio. The deal, reported by Vertiv and covered by StockTitan and GuruFocus, extends Vertiv's thermal chain coverage across heat rejection -- the last stage between data center cooling loops and outdoor air -- and strengthens its EMEA manufacturing base. Separately, Vertiv announced a roughly $50 million Ohio manufacturing expansion in March 2026 to increase liquid cooling and chilled water production capacity by approximately 45%. ### What happened Vertiv Holdings (NYSE: VRT) completed the acquisition of ThermoKey S.p.A. on June 12, 2026, per a Vertiv press release and an SEC Form 8-K filing. ThermoKey is an Italian manufacturer of dry coolers and microchannel-based heat-exchange solutions used in heat rejection -- the step that dissipates heat from data center cooling loops to the outside environment. The acquisition extends Vertiv's thermal management coverage across the full chain: from in-row and direct liquid cooling to free cooling and heat rejection. ThermoKey's technology supports compatibility with low global-warming-potential (low-GWP) and natural refrigerants, which is increasingly required for hyperscale and AI data centers in regions with tightening environmental regulations. ### Manufacturing expansion In March 2026, Vertiv announced approximately $50 million in investment to expand its manufacturing presence in Ironton, Ohio, and Westerville, Ohio (corporate headquarters). The Ironton facility, expected operational in Q2 2027, will increase liquid cooling and chilled water system production capacity by approximately 45%, according to Vertiv. ### Market context AI workloads, particularly GPU-dense inference and training clusters, generate heat at densities (50-100+ kW per rack) that demand liquid cooling at every stage of the thermal chain rather than traditional air cooling alone. Vertiv's sequential acquisitions and capacity investments reflect the infrastructure buildout required to support this density at scale. ### Investment note Insider Monkey categorizes VRT among the fastest-growing data center cooling stocks. The stock-angle context should be read as market color rather than an independent technical assessment. ## Scoring Rationale Vertiv's ThermoKey acquisition (June 12, 2026) is real and substantive, extending thermal chain coverage for AI data centers; Ohio manufacturing expansion adds further context. Relevant to infrastructure practitioners but primarily a business/supply-chain story, not a technical AI advance.
