How do misting systems work?

Misting systems lower air temperature by using specially designed nozzles that inject atomized water into the air. The atomized water droplets absorb heat as they evaporate and lower the temperature in the misting area. This is called flash evaporation. Nozzles are generally placed on the perimeter of the area to be cooled. There are three basic types of misting systems; low pressure, medium pressure and high pressure. Low pressure systems operate off of the household water pressure. Medium and High pressure systems utilize a pump to generate the pressure needed to operate the nozzles.

 

 

High Pressure Systems

High pressure misting systems produce the best cooling results and can be customized for nearly all locations. These systems can lower the temperature by up to 30o F / 15o C.

 

Step 1

Design your system - Layout the area you would like to mist on graph paper. Determine the quantity of nozzles and length of hose you will need.

 

 

Step 2

Choose your Nozzle - Choose the nozzle that best suits your needs.

 

The .006" nozzle (part# 1006) is the smallest standard nozzle orifice available. This nozzle is ideal for applications requiring extremely low flow, with small droplet size, minimal moisture and complete evaporation. The nozzle should not be used at pressures below 500 PSI.

 

The .008" nozzle (part# 1008) is ideal for applications requiring less flow, with small droplet size, minimal moisture, and complete evaporation. It can be used for indoor humidification or outdoor cooling. The nozzle should not be used at pressures below 140 PSI.

 

The .012" nozzle (part# 1012) is most commonly used in areas with extreme heat and low humidity or where the nozzles are placed high above the area to be cooled. It provides comparable results to the .008" nozzle with an increased flow rate. It can be used both indoors and outdoors with complete evaporation. This nozzle will work at pressures of 50 PSI and above.

 

The .015" nozzle (part# 1015) is mostly used for outdoor applications where sufficient airflow and clearance allow for complete evaporation and where higher flows are required.

 

 

Step 3

Choose your Pump - Based on the nozzle you will be using and the number of nozzles on your system choose the proper pump.
