Make Up Water In Cooling Tower

Evaporation (gpm) = Recirc (gpm) × ΔT (°F) × 0.001 Cycles of Concentration (COC) = Make-up / Blowdown Blowdown (gpm) = Evaporation / (COC – 1) Total Make-up (gpm) = Evaporation + Blowdown + Drift

E (gpm) = Recirculation Rate (gpm) × Cooling Range (°F) × 0.001 Example: 1000 gpm system, 15°F range → E = 1000 × 15 × 0.001 = 15 gpm make up water in cooling tower

Makeup water is the volume of water added to a cooling tower system to replace losses from evaporation, drift, and blowdown, ensuring a consistent water level and stable chemical balance . This process is critical for maintaining industrial cooling efficiency and preventing equipment damage. Why Makeup Water is Required Evaporation (gpm) = Recirc (gpm) × ΔT (°F) × 0
