Operating Principle
The machine operates based on the principle of air moisture condensation. The fan draws humid air from the surrounding environment and directs it through the evaporator coil, where moisture condenses into droplets and flows into the water tank or drainage outlet.
The dried air then passes through the condenser coil for reheating before being released back into the room.
This cycle continues until the room humidity reaches the pre-set level, maintaining a consistently dry and stable environment.
