GrowSpan Greenhouse Evaporative Coolers take advantage of the natural relationship between evaporation and humidity to provide robust cooling. When water evaporates, it has a cooling effect, but the amount of cooling that can be achieved is dependent on the relative humidity level within the structure. In the proper conditions, evaporative cooling can be strong enough to cool an entire grow room or greenhouse.

This also makes it crucial to size an evaporative cooling system for a greenhouse correctly, as growers need to know how many cubic feet of space they want to cool effectively. Regardless of the structure’s size or a grower’s needs, GrowSpan can help design a system or entire wet wall that provides efficient, powerful cooling.


GrowSpan’s Evaporative Cooling Walls consist of porous, cellulose evaporative pads that are mounted into either an end wall or sidewall of the greenhouse or grow room. Unlike traditional air conditioning methods, which treat the air that already exists inside a structure, these systems work by bringing a constant stream of fresh air into a growing space. Exhaust fans opposite the wall pull water-saturated air through the cooling pads and across the structure. The water evaporates as the air is pulled along the length of the growing area, supplying cool air as the hot air is expelled by the fans, effectively cooling the whole structure.
