ThermOzone Patented Technology
This patented three vessel system allows us to produce 8 times more ozone, dramatically limiting the use of chemicals and the frequency of draining. By eliminating the direct feed of ozone gas, your water is fresh and odorless, components are protected, and your spa is safe enough to install indoors.
What is an Ozonator?
Ozone is one of nature’s most powerful sanitizers. It works 3000 times faster than chlorine and is used today to sanitize 90% of bottled water. Over 80% of all spa manufacturers only make available a single vessel standard Ozonator that feeds ozone gas directly into the spa water.
Compare Our Purification System
How it works?
- Each day 6,000mg of ozone is converted from oxygen and sent to the internal MDV (Mixing Degas Vessel).
- Water from the spa is fed into the MDV an instantly purified of any bacteria.
- Once the water is purified it is sent back into the spa via an independent jet.
- All harmful ozone “off gases” are sent to a Charcoal Carbon Canister which converts the excess ozone back into oxygen.
- The oxygen is passed back into the internal cabinet to produce more ozone.
