using only a few gallons of water an hour. And outdoor
misting results in a safer, cleaner environment and
provides a more relaxing, cooled surrounding for you
and your family.

How Does It Work?
MIST&COOL™ Outdoor Cooling Systems employ evaporative cooling to effectively cool and condition the environment. Using our proprietary misting nozzles, an ultra fine mist is introduced into the environment which interacts with the air to cool, clean, humidify and to repel flying insects.
Evaporative Cooling Principle
By forcing water through our specially designed misting nozzles, we create a fog of ultra fine water droplets with an average size of 50 microns or less. These tiny water droplets quickly absorb the energy (heat) present in the environment and evaporate, becoming water vapor (gas). The energy (heat) used to change the water to a gas is eliminated from the environment, hence the air is cooled.
Cooling Efficiency
Relative humidity, the amount of moisture in the air compared to the maximum amount of moisture the air could absorb at the same temperature, is a crucial factor in determining cooling potential. The lower the relative humidity, the more water can be vaporized, and hence, the more heat can be removed. Evaporative cooling can be used in most geographical locations. This is because when temperatures reach their peak during the day, relative humidity is normally at its lowest. The graph above shows potential cooling at different temperatures and levels of humidity. To calculate potential cooling using misting, find the relative humidity for the day, follow that to the curve that is closest to the outdoor temperature, then read the potential temperature drop on the bottom line of chart. (Example: 30% humidity (a), 100° temperature (b) = 26° potential temperature decrease ©.)
How Much Water Pressure is Needed
1/2" Professional Misting System
Our heaviest duty system is designed to work with house pressures and pump aided pressures up to 250 psi. Higher pressures produce more water volume and an even finer mist that evaporates more efficiently.
Maximum number of nozzles that can be used at different water pressures with the 1/2 Professional System:
25 psi, 6 nozzels,
40 psi, 18 nozzels,
50 psi, 30 nozzels,
70 psi, 42 nozzels,
180 psi, 54 nozzels,
250 psi, 58 nozzels,
3/8" Do-It-Yourself Misting System
This system is designed for optional installation flexibility and maximum number of nozzles at pressures up to 125 psi. Besides normal patio applications, this system works exceptionally well in greenhouse applications. *Normal house pressures range between 35 psi and 90 psi.
Maximum number of nozzles that can be used at different water pressures for the 3/8" Do-It-Yourself System:
30 psi, 6 nozzels
40 psi, 18 nozzels
50 psi, 30 nozzels
70 psi, 46 nozzels
90 psi, 62 nozzels
100 psi, 62 nozzels
120 psi, 106 nozzels
