OzoneMAX™ is an ultraviolet ozone system that is composed of a weatherproof metallic power box and a high-intensity UV bulb inside of it along with a complete side stream venturi manifold. The system ejects safe natural ozone into the spa’s water alongside the existing pool equipment and is totally dissolved before it enters the spa’s water. When the spa water passes by the UV light bulb inside the power box, the disinfection process takes place immediately.
