Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric current is passed through them. Rosahl dehumidifiers are mounted over a cut-out in the side of the enclosure, and use a small electrolytic membrane to remove moisture from enclosures.
The low voltage electrical charge converts water vapour inside the enclosure into hydrogen ions and oxygen. The hydrogen ions migrate through the membrane and passed through the cut-out. Outside the enclosure, they immediately recombine with air to re-form as water vapour. No liquid water is produced.
