Pad and fan vs high-pressure fogging
Both cool by evaporation; they differ in distribution, water quality and maintenance.
| Pad and fan | High-pressure fogging | |
|---|---|---|
| Cooling effect | Strong near the pad, weaker at the far wall | More even distribution through the house |
| Humidity added | High | High but controllable |
| Water quality | Moderate; pad scaling possible | Demineralised water needed |
| Maintenance | Pad replacement and algae control | Nozzle cleaning and pump service |
| Best site | Dry heat, long narrow houses | Dry heat, wide houses, crops sensitive to wet walls |
Pad and fan is the cheapest strong cooling in dry air; fogging distributes better but demands water treatment. Many projects run pads for base load and fog for trim.
