Please remember to click on the "recalc" button to complete the additions.

WARNING: This calculator is for selection of COOLMAX evaporative coolers only. Do not use this to select a refrigerated cooler as the method of rating is different, and you need a refrigerated cooler with a much larger rating to give the same comfort as the COOLMAX CM50.
