What is Dry cooling?
Dry coolers move ambient air across coils carrying facility water or glycol. They can reduce water use and enable warm-water liquid-cooling loops, but peak-temperature performance and fan energy must be modeled by climate.

How heat moves
Dry coolers move ambient air across coils carrying facility water or glycol. They can reduce water use and enable warm-water liquid-cooling loops, but peak-temperature performance and fan energy must be modeled by climate.

Why teams choose it
- Little or no routine evaporative water consumption
- Simple separation from the technology loop
- Pairs well with higher-temperature liquid cooling
What to validate
- Capacity falls as ambient temperature rises
- Footprint and fan power can be significant
- Hybrid or adiabatic trim may be needed for design-day conditions
