Vertiv acquiring Thermal Key to expand thermal management portfolio (dry coolers, chillers, trim coolers) for EMEA AI data centers
Giordano Albertazzi· Vertiv· AI· 2026-04-22· about Thermal Key (acquired by Vertiv)
“[ Thermal Key ], which is anticipated to close in a few months, we'll expand our thermal management portfolio with great heat exchange know-how and a leading range of dry coolers, a capability for the globe, starting in EMEA. Heat rejection is becoming more complex for AI data centers and a portfolio comprising chillers, dry coolers, trim coolers, offers great flexibility and efficiency opportunities for our customers.”
Why it matters
Heat rejection is becoming a critical bottleneck in AI data center design as power density increases. Thermal Key acquisition signals Vertiv's recognition that thermal management is now a differentiating system-level capability, not a commodity component.
Investment implication
Thermal Key's suppliers (compressors, heat exchangers, brazed aluminum components, controls) should see increased orders. Independent thermal management vendors face competitive pressure from Vertiv's integrated solutions. Component suppliers in cooling systems (copper tubing, refrigerants, electronic controls) face elevated demand.
