Vertiv Buys Italian Cooling Maker ThermoKey: The AI Data Center War Moves to Heat Rejection
Everyone's fighting over GPUs — Vertiv went and bought the company that keeps them cool.
Three Key Facts
On June 12, data center infrastructure giant Vertiv (NYSE: VRT) announced it had completed the acquisition of Italian cooling firm ThermoKey S.p.A.; the deal price was not disclosed. Founded in 1991 and headquartered in Rivarolta, Italy, ThermoKey has spent more than 30 years building heat exchangers, dry coolers, and other heat-rejection equipment, with support for low-GWP and natural refrigerants.
The goal is to own the entire thermal chain. An AI server rack now runs at a power density that traditional air cooling can't handle — liquid cooling is mandatory. But the cold plate that sits against the chip is only the first link; the heat still has to be dumped into the air outside via dry coolers and heat exchangers. Vertiv was already using ThermoKey's components, so it simply bought the supplier — from the chip-level cold plate all the way to outdoor heat rejection, it now controls the whole path.
The focus market is EMEA (Europe, Middle East, and Africa). ThermoKey designs and manufactures in Italy, strengthening Vertiv's EMEA production capacity. ThermoKey CEO Giuseppe Visentini stays on to lead the unit.
WangDou's Take
Everyone tracks how many GPUs Nvidia ships in a year; almost nobody does the math on what happens after those GPUs go into a rack — where does all that heat go? A high-density AI rack throws off as much heat as the air conditioning for dozens of homes. Fans gave up long ago; liquid cooling is the only option. And liquid cooling isn't "hook up a hose and done" — it's a full chain, from the cold plate touching the chip, to the plumbing inside the room, to the giant bank of dry coolers outside the building. Vertiv's move is pragmatic: rather than let heat rejection become the bottleneck on deliveries, it bought the 30-year-old Italian supplier upstream. While competitors queue up for cooling gear, Vertiv makes its own. In this gold rush, the people selling shovels make money — and now the people keeping the shovels cool are cashing in too.
