Aqua-Rex is upgrading its commercial electronic water conditioners for treating hard water.  The two largest standard models, WK4 for treating pipes up to 4” and the WK5 for treating pipes up to 6” now feature a fault-recording system accessible through the LCD display. It provides a complete operating history, including times that the unit has been disconnected and brought back online. This data logging feature is especially valuable in large facilities with interdepartmental and contract workers who might inadvertently disconnect the system and leave it offline, Aqua-Rex points out.
