The calculator below will help you determine the power setting, as a percentage from 0-100%, required during the boil to achieve your target evaporation rate. A typical evaporation rate is 6-8%
for a 60 minute boil, but you can adjust based on your process.
Enter the total power (in kW) of the elements in the kettle, your post-boil batch size (BBLs), your target evaporation rate, and the total boil time. The gauge will indicate the power setting required to achieve your boil-off. If the setting exceeds 100%, adjust your target evaporation rate, boil time, or batch size as needed.
