1. A dehumidification system, comprising:
a plurality of modules each containing a water capture material, wherein said water capture material adsorbs water from a supply airflow in an adsorption mode, wherein said plurality of modules in said adsorption mode fluidically coupled in series to receive said supply airflow;
a first chamber configured to fluidically couple to one or more of said plurality of modules; and
a heating source thermally coupled to said first chamber, said heating source operable to heat an airflow circulated through said first chamber fluidically coupled to one or more of said plurality of modules to desorb water vapor from said water capture material during a desorption mode, wherein one or more of said plurality of modules concurrent operates in said adsorption mode as one or more of said plurality of modules operates in said desorption mode.
