Cooling Tower Calculator Use this handy calculator to approximate cooling tower water use and cycles of concendtration. Remember, TRS can help with water saving designs and treatment systems. Please update the following information as it applies to your tower needs: Gallons Per Minute Design gallons per minute recirculation rate of the cooling tower. Hot Water Temperature °F Design hot water temperature of the cooling tower. Cold Water Temperature °F Design cold water temperature of the cooling tower. Wet Bulb Temperature °F Design wet bulb temperature of the cooling tower. Cycles Expected cycles of concentration of the cooling tower. Daily Load Factor % % of 24 hour period that the tower is in use. Monthly Load Factor % % of month that the tower is in use. Yearly Load Factor % % of year that the tower is in use.
