Misting systems operate on the principle of evaporative cooling. To simplify misting cycle, the process is broken down into the following stages:
1. Water Filtration
Drinking quality water with a Total Dissolved Solids count below 300 parts per million is pre-filtered before being supplied to the misting pump. Water filtration helps prevent nozzle clogging and ensures consistent performance.
2. Pressurisation
An electrically powered high-pressure misting pump pressurises the filtered water to 800–1,000 PSI, pushing it through a closed network of specialized high-pressure pipes and fittings.
3. Atomization
As the pressurized water exits through misting nozzles, it is atomized into an ultra-fine mist consisting of droplets measuring approximately 10–15 microns in diameter.
4. Evaporative Cooling
The fine mist evaporates almost instantaneously upon contact with the surrounding air. This rapid evaporation absorbs a significant amount of heat, leading to a noticeable decrease in temperature and a corresponding increase in humidity.
5. Depressurisation
Misting systems typically operate on an intermittent timer cycle, with 3–15 seconds of on-time followed by 10–30 seconds of off-time. At the start of each off cycle, high-pressure solenoid valves rapidly depressurise the misting lines, completing one full operating cycle.
