Desiccant, What does it do?

Desiccant, refrigerant, low grain refrigerant, with so manyDesiccant Dehumidifierchoices for dehumidifiers what makes one a better choice than another?  The particular application you plan to use a dehumidifier in, will help to narrow your choices as to which kind and size of dehumidifier you need.  Different styles of dehumidifiers operate better in certain conditions and sometimes the size of a project alone can dictate what kind of dehumidifier would be best.

For instance, a desiccant dehumidifier can operate in a wide range of temperatures and still be efficient while a refrigerant dehumidifier is most efficient between 70 and 90 degrees.  So if you are trying to dry an area that is normally in the 50 degree range a refrigerant style unit would not benefit you.   However, a desiccant style unit would still be able to operate efficiently and remove the excess water that you want gone.  These style units have an absorbent material that takes the humidity out of the air in the form of a gas.  Refrigeration style units will take the humidity out in the form of a liquid and so if it gets to cold in the drying chamber these style units will not function as well and will start to collect ice on their coils.

Another determining factor on which style of dehumidifier to use is the size of the area.  If I am trying to control the humidity in a 100,000 square foot space with 10 foot ceilings then I am going to need a totally different kind of unit than if I am working a 1,000 square feet with 10 foot ceilings.  So the next time you are in the

market for a dehumidifier make sure to talk with a someone that can walk you through the process before you purchase some equipment that will not suit your needs.  Whether it is desiccant, refrigerant, low grain refrigerant, or just an exhaust fan buying the right equipment the first time can really make a difference.
