What is the significant difference between misting fans and misting lines?

The two most accepted mist applications are the misting line and the misting fan. The mist line is comprised of a series of misting nozzles in-line with one-another. This creates a curtain of mist which will cool the air. However a mist line relies on nature’s movement of air to cool the surrounding areas. A mist line is usually installed around a perimeter of a building or in an open (non-covered area). Mist lines will produce an ambient temperature drop of about 5-10 degrees. Mist lines work well in dry climates; they however are not as effective in humid climates.

A Misting Fan utilizes “flash evaporative cooling.” By introducing a mist system into the front of a fan, you are moving the mist (flash evaporation) over a larger more direct area. The air movement generated by the fan creates a wind chill which will lower temperatures by as much as 25 degrees.  When trying to cool a humid environment the mist fan is much more effective than a misting line.
