NATURAL SYNERGY BETWEEN HVLS FANS AND EVAPORATIVE COOLING What If Fans Aren’t Enough? While Big Ass fans provide cooling effects when air temperatures are well into the triple digits (>100°F / 38°C), your facility may need even more assistance to become the safest and most comfortable environment. For unconditioned facilities in hot and dry climates, this is an all too common problem with few evident cost-effective and energy-efficient solutions.
How Do Cool-Space Evaporative Coolers Help? To deliver the final step for comfort, Big Ass Fans has the Cool-Space line of portable evaporative coolers to provide dramatically lower air temperatures precisely where they are needed or to distribute cool air throughout a space when coupled with overhead Big Ass fans.

How Do Evaporative Coolers Work? Cool-Space evaporative coolers leverage the vaporization energy of water to rapidly cool air without large amounts of energy consumption. While limited by ambient humidity, the temperature depression through the evaporative units can be significant (Ex: 16°F drop at 90°F/35% RH):
