The complete junk business of pool ozone generators
<< < (3/3)

My hot tub has an ozone generator, the tub is a 1997 model and I'm on the second lamp in the ozone generator. Originally it had a pair of 15W fluorescent chokes in series as a ballast, those shorted and popped the cathodes in the original tube. I replaced those with an Advance electronic ballast designed for triple tube CFLs and that has worked great ever since. I even used the original lamp for a few years, with resistors across the blown cathodes to fool the ballast, it was such a short tube that it had no trouble starting it cold cathode.

You can get dirt cheap corona type ozone generators from China, they're probably no worse than the ones that come with those things, so you could retrofit one of the existing units. If you want bulletproof, use an iron neon sign transformer instead of the electronic driver, those NSTs are current limited and can run into a direct short without burning up.

The reason I mentioned Plasma Technics is that
 their cells
Use a dielectric barrier discharge driven at a few 10s of Kilohertz.  Ceramic doesn't wear out. Their drivers have fault sensing as well.

The Plasma stuff looks really well made, but at what price? No prices on their website.

I managed to repair the crappy Prozone unit by removing the guts and putting in a £80 chinese one from Ebay.

Plasma's Corporate President likes to talk to  Customers. Give him a call. My small psu was -145$. Its built like a tank.
