A device recovers water from an ambient airstream. The device includes a chamber having a group of trays that hold respective amounts of liquid desiccant. A foam media element in each tray absorbs the desiccant to increase an exposed surface of the desiccant to the airstream. Fans and valves are used to control airflow through the device. A charge cycle circulates air through the device to remove water vapor from the airstream. A subsequent extraction cycle removes water collected in the liquid desiccant by a condenser communicating with the chamber. An integral heat exchanger adds heat to the chamber during the extraction cycle. A controller is used to integrate and control device operation. The desiccant trays may be selectively configurable in an array to best suit the intended installation. The trays may be arranged in column and row configurations, along with adjustable airflow patterns between each of the trays. User interfaces are provided to monitor and control operation of the device.
