Imagine working inside a warehouse. You’ve got tons of work to do—boxes to pack, shipments to send—but it’s HOT. It’s more than uncomfortable; you’re sweating, breathing heavy, and feeling woozy. You find it hard to concentrate, and your body’s moving as slowly as your brain.

Whether you realized it or not, you were also likely comfortable in whatever warehouse, factory, gymnasium, or other giant space you were in. That’s because big ceiling fan are designed specifically to work in very large buildings.

Have you ever tried to work in a hot warehouse? Not one that’s just a little toasty, but baking, sweltering, sweat-drenching HOT. If you have, you know how utterly miserable it is. Your body temperature rises, your brain has trouble focusing, and you feel like your energy took a vacation without you. Productive work feels next to impossible.

The comfort of your warehouse employees is essential to their ability to be productive and satisfied on the job. When warehouses get too hot, too cold, too dusty, or too humid, the conditions can be too severe for the average worker to focus and sustain enough physical energy to work consistently all day long, day after day.
