An electrode steam humidifier is an isothermal humidifier which makes use of water’s electrical conductivity properties.

It comes equipped with a filling unit for humidification water, a steam cylinder to generate steam and a control unit which regulates the humidification process or makes it possible for this process to be networked with the central building control system. It also has an outlet connection through which steam can be emitted to an air conditioning system or directly to the room through a ventilation unit.

The steam cylinder filled with water has heating electrodes which are energized. Because of the electrical resistance in the cylinder water, the water becomes heated and is finally vaporized. The limescale deposits which form during the vaporization process require that the cylinder be cleaned or replaced on a regular basis.
