The good news is, there is hope! Cooling a warehouse without AC is possible. In this article, we will discuss practical ways to make your warehouse safe for workers all summer long. Not only will your employees be more comfortable and productive, but some of these options will generate year-round energy savings as well!
Remove the excess heat from your facility by airing out your workspace overnight. If you are in an area where the days are hot, but the nights are cool, take advantage of the fresh air by opening dock doors and windows wherever possible. This essentially re-sets your business, so the temperature is more pleasant the following morning. Installing screen doors and windows will help to eliminate pests and using air circulating fans (more on those later!) will speed up the process.
Of course, this option isn’t practical for all facilities, especially those that are not staffed overnight. But for many, warehouse ventilation will refresh your workspace.
Insulate your warehouse space wherever possible. Doors, walls, roofs… the more insulation, the better. This traps in cool air during the summer and makes it more difficult for the hot outside air to penetrate into your space. This has the added benefit of making it easier to keep your warehouse warm in the winter.
This is a simple one, but incredibly important. Make sure your employees are drinking plenty of water! According to the CDC, when working in the heat, you should drink one cup of water every 15-20 minutes. Allow water breaks whenever possible, and make sure water is easily accessible for all employees. When it is going to be a hot day, encourage your employees to hydrate BEFORE work begins. Remember: by the time you feel thirsty, you are already behind in water consumption.

Portable Evaporative Coolers
Portable evaporative coolers are essentially mini air conditioners that you can move around your facility. The coolers work by pulling air through a wet medium, which acts to remove the heat, and then blowing the chilled air back out into your facility. These evaporative coolers can be small enough for one individual workstation, or large enough to cool an open industrial space. The downside is that these large units are expensive, inefficient and, if not maintained properly, could clog and create unpleasant odors.

HVLS Ceiling Fans
Large diameter industrial fans are one of the most practical and efficient warehouse cooling solutions. These warehouse ceiling fans are known as High-Volume, Low-Speed (HVLS) fans, and they are engineered to move A LOT of air throughout your workspace. Now, technically speaking, these fans don’t lower the temperature of your warehouse. What they do, however, is generate a COOLING EFFECT, which makes your employees feel like it is up to 10°F cooler! HVLS ceiling fans cost just pennies an hour to operate and generate energy savings all year long.
Industrial air circulators are warehouse cooling fans that deliver powerful, reliable airflow wherever you need it most in your warehouse. Whereas HVLS fans move air all throughout your facility, industrial air circulating fans are crafted to provide a cooling effect in a specific area or workspace. Many businesses use HVLS fans and air circulating fans in tandem to cool a warehouse without AC.
