Feature Focus: ClearRay Active Oxygen Clean water System

Ever been in a hot tub that stank of chemicals and made your skin itchy and your eyes red? It's not a pleasant expeience!

Fortunately, there is a new way to keep hot tub water clean and clear with hardly any chemicals at all. It was developed to keep your spa cleaner than ever without an over reliance on harsh chemicals that can smell bad, irritate your skin and burn your eyes

A Unique & Natural System

Using simply oxygen and light, this system is as simple as O3  + UV – C = ClearRay Active Oxygen Clean Water System.

As opposed to expensive optional salt water systems, the ClearRay Active oxygen System™ is included as a standard feature on all Sundance Spas except the plug 'n play Splash series.

Salt Chlorine Generators work by continually turning salt into Hydrochloric Acid. These systems create potentially harmful chemical by-products in your hot tub's water, and can have a damaging impact on your spa's equipment over time, as the Salt Systems  are very corrosive.

The ClearRay Active Oxygen System is a natural process that adds no by-product to the water, keeping your water fresh with no negative effect on your hot tub's equipment.

ProTect Automatic Oxidizer

The patented ProTect Ozone system injects a low dose of ozone into the water before it passes by the ClearRay  UV-C light, energizing active oxygen molecules to work harder to clean the water longer.

This advanced oxidation process naturally activates active oxygen molecules, breaking up contaminants and eliminating up to 9.99% of waterborne pathogens.


ClearRay UV-C Water Purification

The now ozonated water passes by the ClearRay UV – C Light and 99.9% of waterborne pathogens are dealt with. This is done through the diffusion of  ultra violet light (UV-C). UV-C is a natural part of the spectrum of electromagnetic energy generated by the sun.

The UV-C light effectively interacts with the DNA of bacteria and viruses, destroying their ability to reproduce in your water.

UV-C technology is widely used in drinking water plants, aquariums, hospitals and water treatment plants - anywhere where clean, clear, safe water is a priority.

Active Oxygen

It is the combination of these two tools (Ozone & UV-C Light) that creates the perfect environment to reduce the amount of chemicals required to keep your spa safe, clean, clear and balanced.


  • Save Time -  Active Oxygen does more work, so you have to do less!
  • Save Effort - Active Oxygen reduces the amount of chemicals required, making your water easier to keep balanced. 
  • Save Money - Reduced chemical consumption saves you money year round!

As well as saving you time, effort and money, ClearRay Active Oxygen reduces the potential for skin irritants from harmful bi-products or contaminants in the water leaving your skin feeling silky smooth and hydrated. 

Enjoy your spa more, work on it less with a natural system that uses the very latest technology and the power of nature to purify your water instantly.
