What Is UV-C Light?
  • A natural part of the spectrum of electromagnetic energy generated by the sun
  • Effectively interacts with the DNA of bacteria and viruses, destroying their ability to reproduce
  • Is a natural process that adds no by-product to your water
What is Active Oxygen?
  • Water is injected with low-dose ozone and mixed thoroughly
  • Ozonated water then passes through a UV-C chamber where ozone is energized or ‘activated’
  • Activated oxygen cleans the water
  • Using UV-C plus active oxygen maximizes their effectiveness giving you more cleaning power

ClearRay™ Replacement Bulb

To maintain optimum performance levels, an annual bulb replacement is required with the ClearRay™ Water Purification System. The digital control panel on your hot tub will give you a yearly reminder of when a bulb change is required.

It is used in the bottling & beverage industry, the food industry, industrial & municipal water plants, medical hospitals & pharmaceuticals, HVAC systems & cottages, aquariums, aquaculture, fish farms, and many more industries around the world.
