Data Centre Magazine has published a ranking of ten liquid cooling suppliers, placing Schneider Electric first and Vertiv second, ahead of a field of immersion and direct-to-chip specialists. The magazine compiled the list in association with Mitsubishi Electric and frames liquid cooling, meaning the removal of heat from data centre components with a liquid coolant rather than air, as a route to lower carbon emissions.
The top slot reflects breadth rather than a single product. Schneider Electric sells across energy management and data centre power, and completed its acquisition of Motivair at the end of 2024, a purchase the magazine says strengthens the company's expertise in direct-to-chip liquid cooling and high-capacity thermal systems. A senior vice president for Secure Power Europe at Schneider Electric, whom the magazine does not name, told the publication that data centre businesses need to drive electrification and decarbonisation of energy to reach their net zero goals. "We are seeking to lower PUE, which liquid cooling will allow us to decrease even further," he said.
Vertiv, ranked second, brings scale. The magazine counts more than 27,000 employees, business in more than 130 countries and 23 manufacturing and assembly facilities. Recent additions to its cooling range include the CoolLoop Trim Cooler, introduced in March 2025 and built to handle the water temperature variations common in liquid-cooled systems, and TimberMod, a 2023 variant of its prefabricated module families that substitutes mass timber for steel.
Among the specialists, LiquidStack, third on the list, sells two-phase immersion cooling aimed at AI, hyperscale, edge and high performance computing deployments. Fourth-placed Gigabyte offers single-phase and two-phase immersion systems alongside its motherboard and server component business. CoolIT Systems takes fifth; the Calgary company began in direct liquid cooling for desktop gaming and now supplies data centres and server OEMs from its Canadian headquarters and three manufacturing sites in Canada and China.
The back half of the table is largely immersion territory. Iceotope, in sixth, sells chassis-level precision immersion cooling; the company launched KUL AI, a system aimed at 8-GPU servers, in November 2025 and appointed a new chief executive, Jonathan Ballon, in January 2025. Green Revolution Cooling has developed single-phase immersion technology since 2009 and partners with Dell Technologies and Intel on liquid-cooled server racks. Poland's DCX Liquid Cooling Systems manufactures coolant distribution units, coldplates, immersion coolers and dielectric fluids across both direct liquid and immersion cooling, while Submer of Spain and the Netherlands' Asperitas, founded in 2015 and 2014 respectively, complete the group with immersion platforms.
What the ranking does not do is compare like with like. It mixes conglomerates for which cooling is one business line among many with single-product immersion specialists, and it publishes no capacity, efficiency or pricing figures that would let a buyer weigh one supplier against another directly.
For buyers, the list is most useful as a map of who sells what in a market that now spans immersion tanks, two-phase systems and direct-to-chip loops. Shortlisting still requires the numbers the ranking leaves out: cooling capacity, commissioning time, pricing and reference deployments.
