Abstract: An active wheel desiccant dehumidifier is controlled for improved energy savings by modulating operation characteristics including process air flow, reactivation air flow, temperatures, and wheel rotation in response to changing conditions.

Abstract: An apparatus for removing moisture from an air or gas stream by adsorption is disclosed. More particularly, the invention relates to an improved seal and method for removing the seal and an improved L-, V-, or pie-shaped duct that promotes laminar flow (viz. not turbulent) of a moisture- or solvent-laden stream within the rotary adsorption apparatus. This, in turn, reduces the amount of insulation needed as well as isolates the heated duct from the exterior surfaces. The method allows for simplified maintenance of the rotary adsorption apparatus in comparison with conventional seals, which are typically riveted, screwed, or mechanically attached to an adsorption apparatus.

Abstract: Low volume desiccant dehumidifiers, such as dehumidifiers used for the processing of resin pellets, which provide high dehumidification performance, simplified mechanical arrangement and high reliability in a desiccant dryer optimally suited for low volume applications.

Abstract: A dehumidifying apparatus including a carousel ring with a plurality of axial modular desiccant beds, separated from each other, in which the modular beds are cyclically shifted from the process to the regenerating to the process conditions as the carousel ring rotates about a central axis.
