COOLING WITHOUT AIR CONDITIONING
TEMP °F (°C)
Heat And Productivity It’s hard to work when you’re too warm. Whether you are on the shop floor or in the offices upstairs, productivity and accuracy suffer. It sounds intuitive, and it’s backed up by science. Why Use Big Ass Fans For This? Increased air speed takes advantage of the body’s natural cooling process to create a cooling effect through increased evaporative and convective means of heat rejection. Cool-Space evaporative coolers leverage the thermal properties of water to

Why Is Heat A Problem? First and foremost, prolonged and repeated exposure to heat is a safety concern and can lead to serious heat-related illness. Big Ass fans (especially when coupled with Cool-Space® evaporative coolers - more info on page 10) are a proven energy-efficient way to reduce heat exposure and provide a safer and more comfortable working environment.

reduce the dry-bulb air temperature of the air they deliver. All Big Ass Fans products are incredibly effective, energy-efficient, and they are not loud like other industrial fans. Big Ass fans can often replace multiple existing fans, saving critical floor space and reducing clutter.
