How it Works
Misting cooling systems work by using a process called evaporative cooling. This process involves spraying tiny water droplets into the air, which then evaporate, absorbing heat from the surroundings.
The water droplets are produced by high-pressure misting lines, which are typically set up around the perimeter of the space that needs to be cooled. These lines spray water into the air, creating a fine mist of tiny water droplets.
The size of the water droplets is crucial for effective cooling. At 1000 PSI, the water droplets produced are as small as 5 microns in diameter. This small size allows the droplets to evaporate quickly, producing a significant cooling effect.

The cooling effect is strongest in areas with low relative humidity, where the air can hold more moisture. In these conditions, a well-designed misting system can lower the air temperature by up to 12-15 °C (22-27 °F) in the misted zone.
A high-pressure misting system consists of three main components: the pump unit, pressure-resistant tubing, and misting nozzles. The pump unit pressurizes water to 60-100 bar (870-1450 psi), while the tubing carries the water to the nozzles.
Here's a breakdown of the components:
The misting nozzles are responsible for atomizing the water into ultra-fine droplets, which evaporate quickly and produce a cooling effect. The nozzles are designed to prevent clogging and ensure efficient water flow.
The evaporation process absorbs heat from the surroundings, resulting in a significant cooling effect. This process occurs in five stages: water source and pressurization, nozzle dispersion, mist formation, evaporation, and heat absorption.
