During large size commercial water damage it required some special equipment. Great news, SERVPRO the right equipment to get the job done.

"What is a desiccant dehumidifier? The most basic explanation is that a desiccant dehumidifier 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. There’s more to it than that but that’s the brief explanation of how a desiccant dehumidifier works."
