Get the Right Ozonator for Your Spa
If you have done your research, you know that ozone is the most effective method you can choose to sanitize/disinfect your spa. When combined with a low level of Free Available Chlorine, ozone provides a low maintenance way to enjoy pristine spa water.
Now, there are a lot of ozonators on the market. DEL by itself offers 3 models with somewhat different characteristics. Which is right for you?
Ozone versus UV
The very first thing to understand is that UV, even UV ozone, is not as effective as the corona discharge (CD) ozonator in providing a reliable broad spectrum disinfectant. The best of the alternatives to CD ozone, UV ozone is limited by the fact that ONLY water flowing through the light chamber is treated, whereas CD ozone is injected into the water downstream from the pump, so there is a small residual effect. Further, the CD ozonator mechanically controls the ozone production for a more reliable sanitizer that does not require frequent lamp cleaning or replacement.
See the table in DELís spa website to see how alternative sanitizers stack up against CD ozone.
Factors to Consider in Choosing an Ozonator
You can download a spa ozone generator comparison brochure to see which DEL Ozone generator would be right for your spa. In short, the factors to consider include:
Spa size: different ozonators inject different amount of ozone, so the larger the spa, the larger the capacity of the ozonator must be.
Bather load: if you party a lot in the hot tub, get a bigger ozonator.
Electrical service: spa ozone generators come in 120 and 240 volt (or dual voltage) types, so you need to pick the one that matches the power pack in your spa.
Cost: ozonatorsí prices vary widely. Higher priced models should have higher capacity and longer life. Read the fine print.
