Technology Description:

ADMA Products is developing a foil-like membrane for air conditioners that efficiently removes moisture from humid air. ADMA Products' metal foil-like membrane consists of a paper-thin, porous metal sheet coated with a layer of water-loving molecules. This new membrane allows water vapor to permeate across the membrane at high fluxes, at the same time blocking air penetration and resulting in high selectivity. The high selectivity of the membrane translates to less energy use, while the high permeation fluxes result in a more compact device. The new materials and the flat foil-like nature of the membrane facilitate the mass production of a low-cost compact dehumidification device. ADMA received a separate award of up to $466,176 from the Department of the Navy to help decrease military fuel use.

Potential Impact:

If successful, ADMA Products' membrane technology would be 50% more energy efficient for dehumidification and/or cooling of hot humid air than traditional air conditioners.


Increased energy efficiency would decrease U.S. energy demand and reduce reliance on fossil fuels—strengthening U.S. energy security.


Improved humidity control in buildings lowers energy use in air conditioning and reduces the production of mold and other irritants caused by high humidity, leading to healthier indoor environments.


Widespread adoption of this technology could reduce energy consumption for air conditioning of buildings—providing consumers with cost savings on energy bills.
