The Real Impact of Heat
When it’s Hot, Productivity Drops.
When temperatures rise, focus and precision fall. Workers tire faster, make more mistakes, and face higher risk of accidents—all of which slow output, drive up costs, and erode morale across your operation.

Portacool is Built to Conquer Heat in the Toughest Work Environments
ROI Calculator
Heat can have a major impact on your bottom line. So can running an ineffective or expensive cooling system in the workplace. In high temps, workers slow down, mistakes happen more frequently, and energy bills climb, all while companies scramble for solutions and relief. Choosing the right industrial cooling solution isn’t just about comfort, it’s about the return on your investment (ROI).
Using this innovative tool, you can calculate how many dollars you will save annually and over a ten year period by investing in Portacool APEX® Series evaporative coolers. Simply input the size of your space, employee count, zip code, and average cost per kilowatt-hour to see how much profit you can take back from the heat, and how long it will take to recoup the upfront and long-term costs of implementing the APEX Series in your space.
