The Munters dehumidifier, invented by Carl Munters in the 1950s, is still the core product in Munters’ Air Treatment business area
The adsorption dehumidifier’s rotor contains small air ducts with a very large surface area. The rotor is treated with substances that retain moisture or other particles in the air that passes through the rotor.
When the dehumidifier is in operation, two streams of air pass through two sections simultaneously. One is the air that will be dehumidified, the other is hot air used to dry the rotor so that it will be able to remove moisture again.
The moisture is taken away by the hot and very humid air stream.
