Mist and Fog are both created by water droplets. The main difference is density. Density is the amount of water droplets in a given volume of air. Fog is denser than mist and tends to last longer. In terms of visibility (how far you can see through it), fog reduces it to less than 1 kilometer (0.6 miles) while mist can reduce visibility to between 1 and 2 kilometers (0.6 - 1.2 miles).
This will vary depending on the size of the system and the number of nozzles to be used.
Place mist line around the perimeter of the area to be cooled. This forms a mist curtain, a cooling barrier between the protected area and the outside heat. The mist line should be mounted 8' to 10' above the ground.
Cleaning Nozzles - Replace or clear obstructed or clogged nozzles. Nozzles may be cleared by scraping the stainless steel end with flat surface of a knife or screwdriver. To remove nozzle, turn in counter-clockwise direction. Nozzles may be routinely cleaned by soaking in solution of LIME AWAY or CLR overnight. Rinse thoroughly after soaking. Replace nozzle by turning in clockwise direction until snug.
The only maintenance required for a properly designed misting system is a periodic cleaning of the nozzles and an annual check-up for the pump. This check-up may include adding or changing of the oil and tightening or replacing of fan belts (only on the pulley driven pump models), and changing of the filter cartridge. Misting Fan Systems require very little maintenance. We do recommend some preventative care and cleaning for the nozzles.
