Condair OEM steam humidifier is a pressure-free steam generator specially designed for direct or indirect indoor humidification. When water is in the form of pure water, it is non-conductive.Everyday tap water conducts electricity because there is a lot of mineral salts in it.When with mineral salt water through inlet valve into the humidifying barrels, humidification barrels of upper electrode as the water level will increase gradually submerged, because with the mineral salt water is a conductor, so when the water in contact with the electrodes can form pathway, at this time to the electrode voltage, high speed movement, the ions in the water will generate heat, which makes water clean saturated steam heating, and spread by steam device into air conditioning box or duct, so as to achieve to the purpose of air humidification.According to the joule effect, the steam output is proportional to the current, and then to the water level. This current is measured by the current transformer on the main control board.Evaporation when water levels will decline, but with no water in the steam mineral salt, so that the mineral salt concentration in the water will increase, and the conductivity will increase, once the current to reach the upper limit of the microprocessor control configuration, drain valve will get rid of high concentration of water, and then through the inlet valve added new water, achieve the purpose of dilution, so to protect the humidifying barrels.Long-term operation of the scale will be attached to the electrode plate, will block the electrode piece and water ions contact, thus affecting the amount of humidification, so the humidification bucket to regularly clean and replace.
