What is the key difference between a low pressure mist system and a high pressure mist system?

A low pressure mist system is based on using standard hose or tap pressure (30-60psi). Although inexpensive (Less than $500) they lack the key element that makes misting effective. These systems, which are typically sold in home centers and big box stores are also known for getting you and the environment “wet”. Without high pressure the water cannot be atomized into small droplets, which causes the cooling effect of “flash evaporation”. High pressure mist systems operate at 1000psi or more, thus enabling the water to be vaporized and ensures the driest and most effective cooling possible.
