Liquid cooling in AI data centers: an insider’s view from the build side

Datacenter from the inside.
Buildings and Indoor Air Quality
Data centers
Two time options

The decisions being made in data center design rooms right now will shape how AI infrastructure runs for the next decade. Join us in a free webinar, where Vaisala’s Anu Kätkä sits down with Lauri Ikonen, VP Technology and Delivery at Polarnode, for an unscripted conversation about what liquid cooling actually demands from the people building and operating it.

Tune in to listen to a 45-minute conversation coming from someone who has built hyperscale facilities, operated them at scale, and is now developing the next generation of AI campuses. Lauri Ikonen joins the Vaisala webinar series to speak from experience across the full lifecycle of critical infrastructure, from power and cooling design through to operations and expansion.

  • Why compute density, not AI itself, is driving the shift to liquid cooling — and what 100 to 200 kW per rack changes about facility design
  • How direct liquid cooling works from chip to CDU to facility loop, and where measurement becomes the critical variable
  • Why higher coolant temperatures are a major opportunity for free cooling and heat recovery in cold climates
  • Why coolant quality is now an IT infrastructure concern, not just a facilities one
  • How IT and cooling systems could start working together to optimize efficiency based on real-time thermal capacity

Who will benefit most from watching
Data center designers and engineers specifying or building liquid-cooled infrastructure, controls engineers working on CDU integration and cooling system design, facility operators managing the transition from air to hybrid or full liquid cooling, and CDU manufacturers and liquid cooling system providers looking for an operator’s perspective on what matters in the field.
