Choosing The Proper Nozzle Size

The most common question we get is " What size nozzle should I use ?"  

The goal is to achieve the evaporative cooling effect without getting people or furniture wet. There are three primary factors which will determine the Nozzle size:

1. Temperature

2. Humidity

3. Patio height

It is important to note that each patio has additional variables that can affect the evaporation including:  wind, flow through air, and shade,  in addition to the above factors. The following is a general guide to nozzle selection.

.004" ( .10mm)

These are the smallest nozzles available. They create a super fine mist that will evaporate quickly in most conditions. Applications for this very small nozzle would be climates with very high humidity ( over 60% ) and patio height of around 8' ( i.e. Florida )

.006" ( .15mm )

These nozzles are can be used in the following applications

  • Relatively dry climates with low patio height around 7- 8'  and temperatures in the low 100's ( i.e. California )
  • Moderately humid  climates with temperatures in the low to mid 100's and patio height  8'-9' ( i.e. parts of Texas )

 .008" ( .20mm)

Use these nozzles in the following applications:

  • Very Dry climates with temperatures in the low to high 100's and  patio height around 8'  ( i.e. Arizona )
  • Relatively dry climates with temperatures in the low to mid 100's and patio height around 8'-9'  (i.e California )

 .012" (.30mm  )

Use these nozzles in the following applications:

  • Extremely dry climates with temperatures in the high 100's and patio height around 9'-10' ( i.e. Arizona )

 

If you have chosen one of our app controlled pumps, you have the additional benefit of using the interval spraying feature to regulate the mist. Please read the article " The Magic Of Interval Spraying "
