"HydroLight UVO3" is a triple sterilization device that inactivates 99.9% of pathogenic organisms such as Legionella bacteria and Cryptosporidium through a combination of ultraviolet light, ozone, and hydroxyl radicals (OH radicals). (*Certified by NSF Standard 50 in the United States) In addition to improving water quality, it reduces the amount of chlorine used, eliminating chlorine odor and creating natural, environmentally friendly water. It also demonstrates strong sterilization power in alkaline hot springs where chlorine is less effective. [Implementation Example] ⇒ [Wakayama Prefecture, Yukai Resort Nanki Shirahama Onsen Hotel Senjo] Currently active in a 100-ton outdoor hot spring pool (sodium chloride spring). There are also various implementation records in other pools and bathing facilities. [Features] ■ Overwhelming sterilization power (NSF certified in the U.S.) ■ Compact and easy to install ■ Reduces chlorine usage and minimizes chlorine odor *For more details, please download the PDF or feel free to contact us.

Liberty House, Director Sakai's Remarks The water clarity has greatly improved. Previously, on afternoons with many swimmers, the water tended to become cloudy, but that is no longer the case. There is no chlorine smell, and my eyes no longer turn red when I open them underwater. Until now, we had been using sodium hypochlorite, but since introducing Spa Clear, our running costs have significantly decreased. The amount of salt needed is also less than expected, and the initial amount is almost sufficient. I believe this is a very suitable sterilization system for the pool. *For more details, please download the PDF or feel free to contact us.

Statement from the manager of Morimoto Onsenkan In the past, we used chlorine dioxide to prevent chlorine odors, but due to high running costs, we were attracted to the idea that chlorine can be generated from the chloride ions contained in our own hot spring water. There is no chlorine smell, and the chlorine concentration is stable, so we are satisfied. With traditional disinfection methods, there was a lot of hassle involved, such as cleaning the injection valve of the dosing pump and replacing the diaphragm, but that has completely disappeared, which has been a great help. *For more details, please download the PDF or feel free to contact us.
