Patio misting systems are available that lower hot outdoor temperatures by as much as ?? degrees Fahrenheit. They are particularly effective in dry, desert climates, adding therapeutic moisture to the air as well as cool comfort. Patio misting systems consist of a high pressure pump, water lines, and precision nozzles. When water is forced through the nozzles, it forms tiny droplets that flash evaporate to cool the air without noticeable moisture. These misters provide a refreshing atmosphere, perfect for backyard patios and outdoor seating areas at restaurants and other recreational facilities. They add cooling comfort and outdoor enjoyment during the hottest of summer days.
