Cooling Tower Performance Calculator

Cooling Tower Performance Calculator
Calculate tower approach, range, and effectiveness from condenser water and wet bulb readings.

🌡 Cooling Tower Performance

Approach = Leaving Condenser Water Temp − Ambient Wet Bulb Temp

Tower Approach: —

Formulas used:

Approach = TLCW − Twet bulb
Range = TECW − TLCW
Effectiveness = Range ÷ (Range + Approach) × 100%

Explanation: Cooling tower approach tells you how close the tower is getting condenser water to the ambient wet bulb temperature. Tower range shows the temperature drop across the tower. Tower effectiveness combines range and approach into one percentage.

Note: Tower approach varies by design, load, ambient conditions, and tower condition. Compare results against site baseline, design expectations, and recent operating history.

Want to track tower performance across seasons and catch degradation early? That requires a structured log.
