  What FMs need to know about data center immersion cooling fluid selection

  Dennis Schuetzle of Infinium argues that fluid chemistry must be treated as a core operational consideration for immersion cooling deployments.

  • Main announcement/action: The author, Dennis Schuetzle (CTO of Infinium), recommends that facilities teams evaluate immersion fluids as long-term operational variables rather than simple consumables; key factors to assess include viscosity, thermal conductivity, dielectric stability, oxidation stability, and environmental/regulatory profiles, especially as racks move to multi-kilowatt processors.
  • Background and details: The piece is an opinion/analysis column (author views). It compares primary fluid categories — Fischer-Tropsch synthetic hydrocarbons, mineral oils, polyalphaolefins, esters, silicones, fluorocarbons — and explains how production/refining methods, long-term molecular consistency, and aging/oxidation affect maintenance, monitoring, and lifecycle costs; no implementation timelines or monetary commitments are announced.
