Episode notes
Use Dry Cooling Where Water Is Limited
- Use dry coolers when water is scarce because they cool liquid to only a few degrees above ambient without consuming water.
- Use wet cooling only if you must get inlet temperatures below ambient and you can provide reliable water management.
Operational Tradeoffs: Air vs Fluid Cooling
- Hydro tends to be quieter and more pleasant to work around, while immersion matches efficiency but can require similar vigilance.
- Both immersion and hydro demand more consistent monitoring than air because fluid leaks are impactful.
Budget For Higher CapEx On Fluid Systems
- Expect hydro CapEx roughly double and immersion roughly two-to-three times air deployment costs when fully installed.
- Account for tanks, pumps, fluid, and vendor support when modeling ROI for fluid cooling.
