Why Upgrade Your Spa Ozonator?

ZO-301 DEL Industries spa ozone generator is one of the first units DEL sold to spa manufacturers starting back in 1996. If you have a spa ozonator that looks like the ZO-301 (see image) you may want to upgrade to current technology.

Below is a comparison which includes reasons why you might want to consider upgrading from ZO-301 to the MCD-50:

Del Ozone Spa ZO-301

ZO-301 generates approximately 250 PPM, or 40 mg of ozone
ZO-301 consumes 40 mA, 48W (110V)
ZO-301 utilizes old ballast technology which can fail if water backs up, and can cause noise interference in the spa pack
The ZO-301 lamp is rated for 9,000 hours. Replacement costs rise as customers switch to current CD technology
Because the ZO-301 is similar to a fluorescent lamp in an office, it will light up beyond ozone…some say for 18 years. This is a false indicator light which prevents you from replacing the lamp in a timely fashion to ensure your water quality stays excellent

Del Ozone Spa MCD-50

MCD-50 generates approximately 580 PPM, or 50 (to 60) mg
MCD-50 consumes 50mA, 6W for (110V)
The MCD-50 is resistant to water back up and has no noise interference issues
The MCD-50 was introduced by DEL in 2003 to surpass any other technology on the market. It is, to date, in a class all its own
The MCD-50 utilizes CD electrode technology which is incredibly reliable. They have been running five years, most spas 24/7, without failure. Count on these lasting you a good five years, then freshen up your ozonator with a Renewal Kit which includes everything you need to get your MCD-50 up to par again.
The MCD-50, unlike UV technology, will fail when they ozone production has declined. In other words, it’s easier to tell if your MCD-50 is still working to satisfaction.

DEL Ozone still makes the ZO-301 today, and if you plan on simply replacing what you have with the same thing, you can.

But we recommend that you look into upgrading to the Delzone MCD-50...
