Internal Sterilization Flow Path
Internal Sterilization Flow Path
The cooling pipes in Sterra 7 are made from full stainless steel to prevent germs, rust, and contamination.
Electrolytic Water Sterilization — This pumps out any stagnant purified water that has not been used every 72 hours to ensure it only dispenses fresh and purified water. It also cleans up any mineral deposit build-up inside the tubing resulting in a clear flow path, and good water flow.
UV Nozzle Sterilization — This is another sterilization that happens while water is being dispensed through the Sterra 7 nozzle; the UV LED right on the nozzle automatically turns on, further cleaning and sterilizing the water before it reaches your glass.
