How it works
ROSAHL is a unique dehumidifier that utilises a solid state polymer ionic membrane (SPE) to electrolytically decompose and remove moisture from the air by electrolysis when a 3V dc voltage is applied. They provide clean moisture extraction and low cost, maintenance free, and silent performance.
When a voltage is applied to the porous electrode attached to the SPE the moisture on the anode side (dehumidifying side) dissociates into hydrogen ions (H+) and oxygen: the hydrogen ions migrate through the membrane to be discharged on the cathode (moisture discharging) side where they react with oxygen in the air, resulting in water vapour being discharged. Similarly, if the membrane is reversed a humidifying effect is achieved.
