Advantix has developed a line of liquid desiccant (lithium chloride) dehumidiciation air-handling units. These units are able to achieve very low discharge dewpoint conditions, without a tradiitional vapor compression cycle, resulting in significant energy savings. Current models, as of 2012, are challenging to incorporate in a traditional commercial building, due to limited fan pressure capability and non-standard ductwork connection configurations. We recommend keeping a close eye on Advantix's product development. Consider use of these technologies for humidity sensitive applications in ASHRAE Climate Zones 1A, 2A, and 3A.
