Electrolyzed hydrogen water (EHW) is created through the electrolysis of water. Constant electrolysis causes minerals such as calcium to collect at the electrode (on the cathode side), forming a coating. When the electrode is coated with these minerals, Nihon Trim commercial ionizer the process of electrolysis becomes unstable, thus reducing its efficiency. Our EHW apparatus uses a double auto-change cross-line system that switches the polarity of the electrodes and waterway bubbles at regular intervals to prevent the accumulation of minerals on the electrodes and achieve stable, Nihon Trim commercial ionizer long-term electrolysis.
