So what is huge piece of equipment, and all this random plastic every where?
This is a large desiccant dehumidifier, it has a moisture absorbing wheel inside the unit. The wheel is made of silica gel – which is the desiccant (drying) element. Air enters the unit through an opening and travels through the silica gel impregnated wheel. When the air reaches the other side of the wheel it is dry and pushed out of the unit by a high static blower.
Bottom line: It's perhaps the most effective method available of controlling humidity and/or removing moisture from structural materials, hardwood flooring, and providing structural preparation prior to applying coatings.
