Can Aprilaire Dehumidifers be used in pool rooms?

Consumer question:

My engineering firm is designing a whirlpool room at a retirement community. Can the 1770a be used with a fan powered Air Terminal Unit, sometimes called a VAV box but in our case it will be constant air flow. If so, and it seems to me that it would work very well, is there a minimum cfm that the air terminal unit must supply for the 1750A or 1770A to work correctly?

Aprilaires’ response:

Thank you for contacting us with regards to our model 1770A Dehumidifier. Our dehumidifiers supply their own blower to move air. While they would work with the system you’ve designed, it can also work as a stand-alone system. Our concern would be the application, however. Our Aprilaire Dehumidifiers are not designed to work in pool applications. As they often use chemicals to treat the water, when they become airborne, they can corrode the circuit boards inside the dehumidifier. Unless the application will be using a non-chemical based water treatment system, we would not recommend any Aprilaire unit to provide the dehumidification needed. If it is using an alternative method to treat the water, we can offer suggestions based on the size of the application. Please let us know if we can be of further assistance.
