21st March 2026
USA/CANADA: Canadian data centre liquid cooling company, CoolIT, has been acquired by Ecolab, a US water, hygiene and infection prevention solutions provider, for $4.75bn.
Based in St Paul, Minnesota, CoolIT designs and manufactures high-performance liquid cooling systems, including coolant distribution units, cold plates and direct-to-chip cooling technologies.
With over 25 years’ experience, CoolIT’s operations are backed by its Liquid Lab R&D centres in Calgary and Taipei, global manufacturing operations in Canada, China, and Vietnam, and on-site support in more than 80 countries.
According to Ecolab, the acquisition will bolster its cooling-as-a-service offering by combining CoolIT’s anchor thermal engineering technologies and design excellence with its own expertise in water, chemistry, fluid management, digital monitoring and global service.
It enables Ecolab to rapidly accelerate its recurring, high-margin data centre cooling business, by adding mission-critical anchor technologies including CDUs, cold plates, liquid loops and rack manifolds, with substantial cross-selling opportunities.
“AI is transforming the demands on data centres, and liquid cooling is one of the critical technologies that makes advanced computing possible,” said Ecolab chairman and CEO Christophe Beck. “By bringing together CoolIT’s engineered cooling technologies with Ecolab’s expertise in water, chemistry and digital service, we can provide our customers a complete cooling solution that improves performance and reliability while reducing water and energy use.”
