    FUNCTIONING PRINCIPLE The immersed electrode humidifiers of the series EASYSTEAM, exploit the conductivity of water for food use for the production of steam by boiling. In the cylinder, an electric current is triggered between the immersed electrodes; this overheats the water until it is brought to the boiling temperature.
