The gold standard . The CTI (Cooling Technology Institute) offers a certified calculation suite.
A: Yes. Modern software uses the standard formula: Evaporation (GPM) = 0.001 * Circulation Rate (GPM) * Range (°F) , but corrects it for ambient humidity.

For facilities looking to save money, "free cooling" (waterside economizer mode) is a major strategy. This involves using the cooling tower to cool the facility directly when outdoor temperatures drop, bypassing the energy-intensive chillers. Calculation software determines the "crossover point"—the exact wet bulb temperature at which the tower can handle the load without the chiller running. This calculation is difficult to do accurately without software modeling.
For those on a zero budget, check GitHub for repositories like CoolingTowerPy . The gold standard
In this article, we will explore what these software solutions do, where to find legitimate downloads, key features to look for, and how to use them to save your facility thousands of dollars per year.
Not all software is created equal. When you find a download link, you must ensure the tool meets professional standards. A simple Excel spreadsheet might work for basic estimations, but comprehensive analysis requires more robust features. Modern software uses the standard formula: Evaporation (GPM)
A: Fully featured, industrial-grade freeware is rare. However, the SPX Marley Tool is free after registration. For offline, open-source Python scripts are free but require manual assembly.
