Why use ozone in spas?  Ozone is the most powerful spa sanitizer, 200 times more powerful than chlorine at killing viruses and bacteria.  Aiding in the filtration process, ozone clears up cloudy spa water and significantly reduces the need for chlorine, bromine, spa shock and other spa chemicals.  100% natural, organic and biodegradable ozone reduces harsh chemical usage which helps reduce environmental impact.  Yeah!

*Are you replacing a Sundance spa ozonator "6473-125"?  If so, please note you need a 240V/50Hz MCD-50 instead of 240/60Hz. The MCD-50 50Hz works on both 50/60Hz and it comes with EMI coating which is need to prevent electrical noise interference (causing false heat temperature readings, shutting spa down) that the regular 60Hz unit causes.  So, under "Plug & Voltage Options" above, select "Sndnce 50Hz w/Adapter +$8"

DEL Ozone has been supplying hot tub and spa manufacturers with ozone for over 20 years.  If you have a portable hot tub, chances are it already has a DEL Ozonator.
