The evaporation of 1kg of water gives the same cooling effect as the melting of 7 KG of ice. This is nature's own way of cooling air; It produces a considerable amount of cooling effect.

The fog nozzle converts ordinary water into billions of micron-size water particle. When operated at 1000 psi or higher pressure, the fog nozzle generates 10~15micron size water droplets which flash evaporate when floating through the air.

Since rapid evaporation takes place and residence time (time required to evaporate water particles in the air) is kept to minimum; Therefore the natural fog nozzle is a nozzle fully capable of achieving total evaporative cooling potentiality even in climates with high relative humidity.
