A Deѕiсcаnt Dehumіdifіеr іѕ a piece of equiрmеnt that iѕ uѕеd tо rеduсe the humidіty in the air. Many desiccant dehumidifiers are used in industrial applications for drying large areas.  However, there аrе dіffеrеnt tyреѕ of dеhumidіfіers avаilable іn thе market, of which the dеѕіссаnt dеhumіdifіеr iѕ one of the mоѕt effеctivе аnd reliable. Tо bеgіn with, it uѕеs а dеѕіссаnt material (fоr exаmрlе - ѕіlіcа gеl) to be able to remove the moisture from the air in the form of a gas, rather than a liquid.  Desiccant units also tend to be more energy efficient than refrigerant units.  However, the setup and tear down time of a desiccant unit can be a little bit longer.  Especially when using a large trailer mounted desiccant dehumidifier. 


How it wоrkѕ: The dеsicсant materiаl is generally mounted inside the machine on a rotor.  As the rotor turns moisture laden air from inside the structure is brought into the machine and passes through the desiccant material.  The rotor will continue to turn and pass the now moisture laden desiccant material through a heater.  As the material is heated it will release the moisture it has collected and be vented outside the building.  Then the rotor will continue to turn and the material will cool down so that when it gets back to the moisture laden air coming into the machine it can absorb it again and the process continues. 

Desiccant dehumidifiers work well in a wide range of temperatures but would be preferred in areas that tend to be below 70°.  So this can make them more useful than refrigerant style dehumidifiers in certain scenarios and climates.  Refrigerant style units do not work well at temperatures below 70°.   However, desiccants do not collect water in a liquid form, but in a gas, then you do not have to worry about them getting too cold and starting to ice over like refrigerant units. 

Desiccant dehumidifiers are also widely used in the water restoration industry to dry large buildings because they can process large volumes of air a lot more efficiently then refrigerant style units.   Some large trailer mounted units can process 10,000 – 12,000 cubic feet of air per minute (cfm).  Smaller more portable units can also be used by water restoration companies when they need to dry more difficult items like wood flooring.  Besides these uses, the units have many more residential, commercial, and industrial applications and are in use all over the world.

As with all dehumidifiers, to work correctly they must be sized properly to the space you are trying to dry.  If not then you will not be able to achieve the results you want.  So the next time you are in the market for a dehumidifier that will process large volumes of air look for a desiccant dehumidifier.
