Why Big Money Is Pouring Into AI Cooling

Liquid cooling has become one of the most important technologies in the rise of AI. Powerful new AI server hardware throws off a lot of heat, pushing past the limits of most traditional air cooling. This has driven a surge of acquisitions in the cooling sector, and none bigger than Ecolab's $4.75 billion deal to acquire liquid cooling specialist CoolIT Systems.

In this episode of Data Center Richness, host Rich Miller sits down with Jason Walker, Director of Product Marketing for Data Centers at Ecolab, to break down the CoolIT acquisition.

Walker discusses how Ecolab is pairing decades of industrial fluid management with CoolIT's cold plates, CDUs, and manifolds to solve critical operational bottlenecks. Learn why fluid health and monitoring matter during commissioning, how joint R&D at CoolIT's 6MW Calgary facility aims to extend single-phase cooling limits for extreme densities, and how integrated hardware and chemistry simplify lifecycle operations for hyperscalers and multi-tenant colocation operators.
