  • Page 25 App. A HUMIDAIR HUMIDIFIER App. A.1 Electrode humidifier The operation of immersed electrode humidifiers is based on a very simple physical principle. As common drinking water contains a certain quantity of dissolved mineral salts, and is consequently slightly conductive, applying a volt- age to metal electrodes immersed in the water creates an electric current that heats the water until producing steam (Joule effect).
  • Page 26 The steam production rate can be controlled by varying the water level in the cylinder; the higher the water level, the deeper the electrodes are immersed into it and the greater the steam production. Note 1 In case of low water conductivity consult Vertiv Service. Liebert CRV, Chilled Water - UM - 265381 -12.01.2018...
  • Page 27 Note 2 When starting with an empty cylinder, the water conductivity is normally insufficient for the HUMIDIFIER STEAM OUTPUT to be reached immediately. Therefore the humidifier produces as much steam as possible to fill the cylinder completely. Any evaporation water is immediately refilled. The drain valve is kept shut and therefore, as the steam does not contain any salts, the conductivity of the water within the cylinder slowly increases until the HUMIDIFIER STEAM OUTPUT is obtained.
