Portable Evaporative Cooling Units provide spot and area cooling where you need it, when you need it. Evaporative cooling is a time-tested and efficient means of reducing air temperature by drawing incoming air across a wetted surface.
Evaporative cooling is especially useful in situations where air inside the space to be cooled is well ventilated. Evaporative cooling needs only two factors to work: water and moving air.
When air is moved across a wet surface, some of the water on the surface evaporates. This action draws heat from the moving air, thereby cooling and dropping the ambient temperature.
