Enerzen Ceramic Plate Replacement for O-555 and O-777 Ozone Generators

Perfect fit! Easy to install, just remove the screws on the sides of the case and swap it out. There was plenty of heat transfer past left on the cooling block, so no need for more. I previously bought another brand that was supposed to be compatible, but it took a lot of modification and soldering to get it installed. This one just works!

Our company owns two Enerzen o-777 and two o-888 ozone generators that we use for apartment de oderizing. These plates are for the o-777. We use the ozone generators A LOT. I've only had to replace one ceramic plate in February of 2022 and the unit has worked perfectly ever since. I like to use a mechanical timer so they run on a schedule at night in vacant apartments. Be sure to get some thermal grease...

Update: The seller was good enough to offer me a 50% refund on the cost of new unit. They are clearly concerned about customer service. I can't ask for better than that. Thanks to them.Previous:The ozone generator itself is top notch, works great. But, after 4 years, it quit producing ozone. The company sells parts, so, no big. In the pics, I show the original plate (blue) and next to it the replacement (white). I gently removed the old plate. The other pic shows the block it mounts on, and residual heat sink compound. It was clearly making contact with the block. I gently inserted the new plate. It did NOT make contact with the block. This looked pretty "idiot proof", so I really didn't understand the problem. Swapped the original back in, verified that it sat in the holder, making contact with the block, no gap. Again put in the replacement, and saw a gap. Thinking it just wasn't seated right, I gently pushed it down to contact the block...and it snapped. It's a ceramic block, so it doesn't flex. Anyway, my point is that the plate you'll receive is different from what they show in their photo. And, apparently, there is a slight difference in physical dimensions. Not really worth your time to buy this, learn that it won't work, and then have to go to the hassle to return it.

Good replacemnt, works as expected. What isn't obvious, is that this needs thermal paste for the heat sink. You can scrape off the existing past with a spatula or plastic card and reapply it to the back the new ceramic part, but if it is dry you will need to clean off the old paste from the heating and apply new paste. If you skip the paste you will burn this plate up prematurely. I would have given 5 stars had it come with new thermal paste.

It works well. Easy to replace. Need to make sure you get thermal paste for install. Keeps my investment working.

I used thermal paste when installing the new plate. It only lasted about 3 weeks of non-continual use. Very disappointed.

This restored the functionality to my ozone generator. I wish it came with a bit of thermal paste because you will need some to mat it to the heat sink

Other reviewers let me know that I would need thermal paste, and that there would be a little gap between the base of the plate and the outlet it plugs into.No one mentioned that I needed to pull up on the black plastic on the top of the heat sink to fully install the plate and let it lie flush with the heat sink, but I figured it out.The plate was shipped in a paper mailer, but it's packed well in it's box with a styrofoam cushion and arrived intact.So far it's working perfectly.
