300 Series

The Hydro-Guard® 300 Series Automatic Flushing System is ideal for distribution systems with problematic disinfectant residuals or where taste, color or odor issues lead to customer complaints. The below ground design of the 300 Series system reduces the potential for freeze damage while allowing utilities to enhance water quality by flushing, collecting quality samples from the flushing system, and conducting flushing operations when water quality conditions warrant. The below ground installation is aesthetically pleasing to customers who are opposed to having pedestal enclosures on their property, in addition to reducing customer complaints related to flush events and related water usage. 

With the available Bluetooth controller, authorized operators can schedule up to 24 different flush events into the controller through a free K-Rain KRBL V2 app than can be added to most iOS or Android phones. Flush durations can range from one (1) minute to six (6) hours per programmed flush event. Where the use of a mobile app or Bluetooth is not permitted, the 300 Series can be equipped with a built-in NODE programmer. The NODE programmer allows for scheduling of flush events multiple times per day, multiple times per week. 

The 300 Series Automatic Flushing System is equipped with an OEM-installed Dechlorination System and an onsite, OEM-installed Sampling System to allow water quality samples to be drawn directly from the flushing system.
