Industrial Desiccant Dehumidifiers

Interesting topic. I'm not sure about the correct rate to remove moisture and prevent potential warpage of the construction materials. Correct Unit sizing would have many variables not only the square footage, how well the building is sealed, etc.

They're too widely used methods for removing humidity. Desiccant dehumidifiers and refrigeration based dehumidifiers. The refrigeration based units are generally less expensive to buy, and depending on conditions they may be less expensive to operate. I would carefully investigating the refrigeration based units before deciding to purchase a desiccant-based unit.

Refrigeration based units perform well in less you are trying to reduce the relative humidity below 40%, desiccant-based units really have no lower limit.

When working with clean rooms and laboratories where it is necessary to control humidity, I've generally use refrigeration based units in less the maximum allowable relative humidity requirements of the room are extremely low.

I'm just guessing here but I do not believe that you would want to reduce the relative humidity to or below 40%. I would think it will be better to stay within the normal range of relative humidity in your area for your purposes. I have included a couple of links that describe both types of units, and also retail dehumidifiers. Talking to their representatives would undoubtedly be a good source of information for sizing, and recommending correct rates of drying to prevent warpage in the wooden building materials.
