🏢 CTI Standard Range (10°F), Approach (7°F), Evaporation GPM = 0.0008 x GPM x Range

Commercial Cooling Tower Evaporation Calculator

Size open and closed-circuit evaporative cooling towers (Marley / BAC / Evapco) under Cooling Technology Institute (CTI) standards: calculate Cooling Range (°F = Entering - Leaving Water Temp), Approach to Wet-Bulb (°F), total hourly water evaporation rate (GPM = 0.0008 x Circulating GPM x Range °F), and water treatment contractor margins.
