Sundance Spas

SunZone™ CD System
The SunZone CD options on system-ready models utilize ozone technology to effectively remove water impurities and micro-organisms. Reduced chemical usage and less maintenance are the two most significant benefits you get from using the SunZone CD system, found only on Sundance spas.
The units use a highly efficient corona discharge (CD) element to maximize ozone production and provide clear water, surpassing the capabilities of UV-ozone options. Ozone maintains the water balance longer; so the spa will not need to be drained, refilled, and reheated as often. SunZone CD is standard on export models.


Sundance Spas’ water filtration technology improves water clarity while reducing chemical usage and maintenance. The SunZone™ mixing chamber on select models triples the positive effects of ozone, which further improves water quality. To reduce maintenance and lower operating costs further, choose one of the models that are ready for easy installation of the latest in ozone purification technology.
