Cooling Tower Performance: induced_draft_counterflow
Cooling tower performance data — typical approach temperature, range, nominal tons per cell, GPM per ton, and air flow CFM per ton by tower type and capacity range
| tower type | design wet bulb or capacity | air flow cfm per ton (cfm/ton) | approach F (F) | gpm per ton (gpm/ton) | nominal tons per cell (tons) | notes | range F (F) |
|---|---|---|---|---|---|---|---|
| induced_draft_counterflow | large_800_plus_tons | 330 | 5 | 3 | 1,500 | Large counterflow; approach can be tightened with more fill depth and airflow | 10 |
| induced_draft_counterflow | medium_200_800_tons | 350 | 6 | 3 | 400 | Medium induced draft counterflow; preferred for close-approach requirements | 10 |
| induced_draft_counterflow | small_50_200_tons | 370 | 6 | 3 | 125 | Induced draft counterflow; counter-airflow slightly better thermal effectiveness; smaller footprint than crossflow; typical 95/85/78 design | 10 |
