For edge data centers 10MW and below, some of the modern assumptions around cooling start to break down. Chilled water is still the default in larger facilities, but at smaller sites, the balance between cost, complexity, and flexibility looks very different. More modular approaches, including refrigerant-based split systems using thermosiphon technology, are starting to come into play, raising questions about what actually delivers the best long-term value. This session looks at how the TCO compares across these options, and what really matters when making that decision at the Edge. Join this episode to discuss:
- How TCO stacks up between chilled water and refrigerant-based systems in sub-10MW sites
- Where modular, split systems start to make more sense than traditional setups
- What thermosiphon and hybrid heat rejection actually change in terms of energy use and upkeep
- How much factors like climate and power pricing really shift the cost picture
