Evaporative Air Cooler KT-1E

KT-1E– BASIC PRINCIPLE
The cooler is a high-tech product, originally from Europe. It is made in
accordance with European high technology.
Its working principle is that water evaporation drives away the surrounding
heat and causes the temperature to cool down.
When water is continuously distributed onto cooling pad surface evenly, the
wet cooling pad makes air cool and fresh. The circulating water falls to the
bottom, forms the water cycle. There is a water level indicator at the
bottom. So when the water level indicator reaches the bottom level, the
inlet valve will open automatically to add water; When the water reaches
the indicated full level, the valve will close automatically.
