Based on the principle of evaporation, the RainMaker cooling system is largely effective in regions having hot and dry summers. The cooling effect is directly proportional to the temperature and inversely proportional to the relative humidity. It is a centralised system that comes with a pad retainer, top profile, and water reservoir.
In addition to the traditional cellulose pads, Big Dutchman also recommends the use of plastic pads because they come with a comparatively long service life and can be cleaned using a high-pressure cleaner.
