7AC has licensed 7 patent applications from the Department of Energy’s National Renewable Energy Laboratory (NREL) and has independently filed 16 patent applications around design concepts.

The 7AC technology consists of an all-plastic conditioner, responsible for treating the outside air, and a regenerator, for re-concentrating the desiccant. The liquid desiccant design allows for the utilization of waste heat sources, paving the way for true net-zero energy retrofits.

Our proprietary membrane design guarantees zero salt carryover into the building air by confining the salt to the plate surface while allowing the free transfer of water vapor. 

We have the ability to cool in summer and recover heat and moisture in winter, giving our system year-round utilization with compelling payback terms.
