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.


The rotor consists of a corrugated fiberglas structure, which contains a hygroscopic material (desiccants such as silicagel or lithium-chloride). 

Munters innovative rotor design is constantly ongoing and 6 different rotor types are available to suit our customers individual requirements.

Health, Safety and Hygiene for customers is essential to Munters which is clearly reflected in the design of the rotors. Our rotors are continuously being tested independently and have most recently been proven by The Swedish Institute for Food and Biotechnology to have both bactericidal and fungicidal properties.
