Understanding Our Technology
How Our Dehumidifiers Operate
1
Step 1: Electrolysis
When 3 Volts D.C. is applied to the SPE’s electrode, the moisture in the enclosure is attracted to the membrane where it breaks down into hydrogen ions and oxygen.
2
Step 2: Ionic Membrane Action
The hydrogen ions (not hydrogen gas) migrate through the membrane for discharging on the outside where they react with oxygen in the air, to form water vapour.
3
Step 3: Enclosure is dehumidified
With zero air exchange, the process removes the moisture in the enclosure in the enclosure to the required level. It is maintenance free and inexpensive to run.
