💧 CTI Water Balance (Evaporation E = 0.0008 x GPM x Range, Blowdown B = E/[COC-1])

Cooling Tower Water Balance Calculator

Calculate water consumption, evaporation losses, and automated blowdown flow for commercial open cooling towers under CTI guidelines: calculate Evaporation (E = 0.0008 x Circulating GPM x Cooling Range °F), optimize Cycles of Concentration (increasing COC from 3 to 6 saving millions of gallons of municipal make-up water), and water treatment profits.

1. Project & Operating Inputs

Circulating Condenser Water Flow (GPM e.g. 2,400 GPM Plant Circulation)

Cooling Range (°F e.g. 10.0°F Delta T [85°F Supply / 95°F Return])

Turnkey Automated Blowdown & Chemical Feed Skid CapEx ($ e.g. $38,500)

Combined Municipal Water & Sewer Rate ($ / 1,000 Gal e.g. $12.50 / kGal)
