Munters Dessicant Rotor
The basic idea of the Munters desiccant drying wheel (Rotor) is very simple: Air is blown though the rotor structure and the humidity in the air is absorbed by the desiccant. The air leaves the rotor as Dry Air.
A drive motor turns the rotor around slowly (6-10 times an hour).
The rotor structure passes a seperate sector where hot (reactiviation) air is blown through the rotor to remove the accumulated moisture. The resulting wet air (which contains the removed moisture) is blown away outside.
