Many other names have been given to this invention: Sorption rotor, sorption wheel, desiccant rotor, desiccant wheel, honeycomb rotor, honeycomb wheel, drying wheel, drying rotor, etc. etc.
The basic idea of the Munters Desiccant 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).
The system only has a few moving parts: one or two fans and a drive motor. No freon, no compressor.... just Simple Magic.......
Inhouse rotor development and production
Munters innovative rotor design is constantly ongoing and 6 different rotor types are available to suit our customers individual requirements.
Improvements in the structure of the rotor, the absorbents and design allow a remarkably energy efficient dehumidification process.

Certified rotors for your safety
Customer health and safety 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. Not only the rotor surface but also air streams were tested.
Furthermore the rotors are proven not to emit particles to the processed air and the rotor fibres used have a size not respirable and preclude associated health hazards.
