DEL Hot Tub Ozonators & Ozone Parts

Install an ozone water purifier in your hot tub and use far less sanitizers, water clarifiers and defoamer chemicals. You'll have a cleaner and clearer hot tub water and won't have to change your spa water as often. By reducing bromine or chlorine use by 60 - 90%, the water will be less abrasive to your skin and eyes, and have much less of a "chemical odor".

If you install an ozonator and operate it at least 3 hours in every 12 hour period, you can keep the sanitizer level much lower than normal. Bromine can be kept as low as 1.5 ppm and Chlorine as low as 0.5 ppm. You'll also find you won't need as much sanitizer to keep the reserve at the required level because ozone is doing most of the purifying.

The advanced technology in corona discharge ozonators made by DEL Ozone, do not contain an ultraviolet bulb that requires replacing. These ozonators are powered by an electronic chip which is more reliable than a UV bulb. In addition, corona discharge ozonators save money because they use less energy (no lamp, ballast, or starter) than an ultraviolet generator. These ozonators use solid state electronics to eliminate voltage spikes that can upset spa pack electronics or trip the G.F.C.I. Finally, water backup into Corona Discharge ozonators will generally not harm the internals.
