High power ozone generator teardown with schematic

We had been using one with electrodes sandwiching six inch glass tubes, with the whole apparatus being about 6 cubic feet. When I left, the company I was working for was all aflutter about getting one the size of a toaster, and now this.

I have one of these. They really do produce a metric ASS LOAD of ozone in seconds with both plates running. You definitely do not want to be in the same room. I bought it to cure a flea infestation in a house I moved into. Fixed the problem within a week.

[@Wirralguy]

Yep, I have one in a plastic box with a 4" fan and it is certainly an efficient way of getting odours out of a car. I leave it running for 10 minutes with the air-con on recirc and that's all it needs (well apart from the half hour airing out afterwards).

Our local farmer uses a box with TWO of those (and a 120mm p.c. fan) to produce enough ozone to fumigate barns / storage areas. He finds it excellent for residue-free control of everything from fungi / moulds to the "larger" pests - particularly cockroaches. They may be immune from everything else, but ozone does them in quickly and efficiently. Also great for reducing the pong in the milking parlour during quiet times (and of course is a great sanitising agent!)

[@phils4634]

I've often wondered if the very enhanced oxidation potential of ozone (in combination with the usual Aussie hot, dry summer weather) might increase the risk of spontaneous combustion in e.g. silage? Since most of the heat's produced by microbial metabolism (and the ozone kills off the microbes), the reduction in local heat generation might offset the oxidiser effect of the ozone? Almost worth a small (undergrad. level) research project perhaps?

I used one of these to replace the failed 60hz AC HV transformer in my old commercial ozone generator. 85 Watts! into 4 3x5 inch double sided stainless mesh on ceramic plates. (I binned the originals) It will run you out of the room in a couple of min. Good thing it has a timer. My generator had originally a .5A breaker on the HV side. I had to change it to a 1A since its pulling 85 watts now. Mine seems to be one power level down from the one that you have, judging from the length of the heat sink. the 40 W one has a heat sink about 1/2 the length of the case. Mine is about 80% of the length of the case. Yours is the big dog!

At least for once or so, I was correct and finally have identified the blasted part. Thank you so much ! =) The story may easily ended here, but things are not always as easy as expected. Wise from the blast in my past, before powerup I measured fwV of the NPNs whom probably was the main cause rather than collaterals, and I had offcourse only some smaller MJE13005 as a somewhat almost nearby complimentary. But I have like a ton, or at least a small bag full of IRF 740 "N" mosfets, and I cant really see why they wont do the job just as good. But something one not can see, can just as well only be an issue regarded blured vision from these marvelous bewildered beverages one may randomly endeavour. I have also a lot of the bigger IRFP460 that could be tried, but my main consern is to rather understand whats going to happen, rather than just learn by "Trial and terror" so my question for you is that if I am missing some details, could you please give a minute and mention what I may ignore, then it would be just as highly appreciated by me as probably my dear tenant, whom gets unusually scared everytime the main fuses randomly blow by complete mysterious manners.

Hi Clive. I've had a pair of these for well over a year. One 120v🇨🇦 and one 12v. I didn't like them being out in the open so I made square glass "tubes" for them and added small fans. If odour is any indicator, the 120v one produces more ozone than my small (-ish) commercial unit! I haven't had the right testing equipment, but I recently bought some. Now all I have to do is figure out where I put the things! They were on display (they sat on a shelf near my work table), but I think I must have moved them to storage. Now they may never be found. Don't store things unless it's in translucent plastic containers! Of course after watching this, I'm going to have to waddle through the snow into my storage and try and find them. Sigh.

Several mechanisms have been suggested for the bactericidal action of ionizers including electrical phenomena, effects of negative and positive ions and electrostatic repulsion. Negative and positive ions have indeed been shown to have bactericidal effects. In addition, since ozone is generated along with ions, these may contribute to the bacterial killing. In this study, we used a newly developed ionizer, which generates a relatively low concentration of ozone, to determine whether its effect on bacterial cells were due to ions or ozone, and, if ions, how the ions exerted their effects. Results The effect of ions on bacterial killing was compared with that of the ozone produced using an ion trap to remove the ions. The ionizer had the ability to kill the bacteria, and ion capture dramatically reduced its bactericidal effect, indicating that the ozone generated had little or no bactericidal effect under these conditions, and the ions produced were responsible for almost all the bacterial killing. Operation of the ionizer increased the level of 8-oxo-dG, a marker of oxidative DNA damage, and decreased aconitase activity, which is known to be sensitive to ROS. The ionizer further affected the adenylate energy charge of bacterial cells. Removal of the ions with the ion trap greatly reduced all these effects. Conclusion These results indicate that negative and positive ions generated by the ionizer are responsible for inducing oxidative stress and so reducing bacterial survival.

Was only 8 pounds when i bought mine too pre coof... the ceramic plates are very very fragile... any slight bending on the metal backing substrate will crack them as they are bonded on with some thermal type goop. I consider myself sufficiently clued up with electronics and safety to not hurt myself but was actually a little surprised how easy it was to buy such a thing that can easily cause severe harm from a mainstream website. Probably since the coof people have been buying more of these types of things as I've seen these things advertised as antiviral etc? I think you covered it really but they will overheat and die without proper cooling, electrical safety is non existent unless designed into a suitable project, the ozone emission is insane, easily very bad for your respiratory system if you don't know what you are doing.

Those produce HUGE amount of ozone when new but may not last too long (especially in high ozone level environment). My diy sterilizer cabinet has one that is pretty worn out and does not produce that much ozone. It needs a replacement unit any day (that I have a few). Ozone is great for sterilizing stuff like FFP2/FFP3 masks that can be sometimes hard to find or at least very costly. I never knew last year how much FFP2/FFP3 respirators I'd be using in a daily life. For any DIY solution, make sure you know what you're doing. Studies indicate a need for enough dose + humidity. If you put way too much ozone, rubber bands will fall of respirators and the screws will oxidize badly. Don't ask how I know, just debug better your software :)

how long did it last?

[@hoggif]

​@@termivan The question is how long will it last. My 65 liter cabinet has had one from the beginning of the pandemic and it is still going on well. I've used levels of about 70-150ppm for about 1-2 hours weekly or twice a week. It runs with PID controll and the duty cycle is probably something like 25%. (It just tops up ozone when it is used or decomposes and more at the start of cycle. One with 3 ozone generating plates is overly powerfull for that) Plenty of use hours and I have a spare at hand for the day it will fail. The generator is inside cabinet ie. not just generating ozone that is blown away but exposed to ozone all the time. It still goes strong but produces less ozone (I'd guess like half) than when it was new. It has taken some very high level cycles though, like way over 2500ppm that already corrodes metals like screq heads visibly. (no way to say how high, I can measure only up to 2500ppm) This can give you some idea of what kind of abuse it has taken.

The holding hands don't matter, Clive. There is no person attached anymore, so no worries

It's a self-oscillating ZCS LLC converter. Very neat!

[@doncodman913]

Ozone... isnt it that smell i used to get from the model railway as a kid when the engine is just about to move after buzzing and humming at the low voltage ? rgds Don

[@dennisolsson3119]

Simple! :) Can't you measure inductance to get the ratio of the windings in the transformer? I could be wrong thought. How would these plates perform on the normal voltage multiplier ladders? For DIYing if nothing else.

[@mohamedrasheed201]

How can I diy transformer

[@BonkedByAScout]

What used more power: The Ozone generator or everyone's subwoofers playing that sound back?

[@bigclivedotcom]

Technically speaking it would be collective power consumption of the subwoofers.

Hi, I have just purchased a unit from China and have a question. The unit is a complete cased unit with what looks like the same internals as this video. I put in the offending room and left running when I was not at the property. Got a call about 15 minutes later saying that the interlinked smoke alarms where going off in the property. The room apparently had a slightly hazy look to it. Inside the room was bedroom furniture including a memory foam mattress. Have used the unit again in a car for 15mins and no appreciable haze and just a strong not unpleasant chemical smell is what I can pick up being released by it. Thanks for reading.

[@bigclivedotcom]

Ozone itself has a smell like bleach. I'm not sure what caused the haze in the room. It's possible that it interacted with airborne VOCs. I wouldn't recommend leaving these units running in a room for a very long time, and definitely not unattended. Also take care to limit human/animal/plant exposure to ozone. Especially when the unit is running. It's best to air rooms out after use to dissipate residual ozone.

[@rustblade5021]

it is meant to be installed in an air handler plenum

[@Erik_Swiger]

Wish me luck! I found this video while doing research. I have a commercial ozone generator, and it's not working right. It's very simple, and I think it just needs a new capacitor. Problem is, I don't know the specs on it, and the existing capacitor is potted in a black epoxy. I'll test it, and if it fails, tear it apart to attempt to find the numbers.

[@minusmagis]

Really nice work, as always :) One question, if the circuit is reminescent of those of halogen lamp drivers, and it is self oscillating at high frequencies do you think it would be possible to dim the power via a Leading-Edge Dimmer circuit? Or do you think it would mess up with the self starting oscillation? My guess is that it should be possible down to a certain threshold where the circuit would not self start (and I wonder what would happen there, if there would be some kind of damage). Cheers!

[@mattmoreira210]

I know your question wasn't directed towards me, but I hope you find my answer helpful. I'd use a trailing-edge dimmer with that circuit. A leading-edge dimmer would pose additional stress to the circuit's capacitors.

[@minusmagis]

@@mattmoreira210 Hey Matheus, thank you very much. If that is so, do you thing this circuit could be dimmed somehow? Maybe using a simple transformer would be the simplest option right?

[@Dekko-chan]

I picked up one of these and i dont like the smell of ozone but it did make my room smell much better

[@5Komma5]

They are sold as either 10 or 20 grams per hour ozone generators. What would you use that for? House "fumigation"?

[@bigclivedotcom]

Large area sterilisation while unoccupied.

[@nw8000]

Did you manage to fix it then?

[@cs_fl5048]

The case and tubing looks just like that used in the airline ozone tube you took apart back last May. Same company? or just standard parts?

[@patelnrupesh]

Thanks for nice information. Is potentiometer possible to set power in this circuit? What can i do for reduce power in this circuit?

[@BedsitBob]

Is this unit not meant to be installed into an AC conduit, or similar?

[@TravisTerrell]

These things are awesome, but they come broken 40% of the time. Also, in my experience the transformers die prematurely, but a fan keeping them cool helps some. Edit: So there's more than a xformer in there? Interesting. Mine are all potted up.

[@SigEpBlue]

Start of video: "Oh well, that looks cute, possibly interesting. Bet it draws about 20-30 watts." [Clive plugs it in, draws >150 W, cacophony of corona discharge, heavy smell of ozone chases Clive out of room.] Five minutes into video: "JESUS...that thing is serious! I love it!" :D

[@ravanabrahmarakshas4263]

tech question: i made an ozone generator. electronic circuit is from a jacob ladder. for the generator part, i used two layers of aluminum mesh and between them is a 2 mm glass. 30 by 20 cm surface of mesh. i have put a fan that moves the O3, and it cools the glass too. so far its glass is not broken, but after your description for breaking glass because of heat i am getting concerned. i think fan will cool the area as well and it wont break. your comment? thanks

[@bigclivedotcom]

If you run out for a while then turn it off, and the glass isn't hot it should be OK. Remember not to have too much ozone in living areas.

[@mohamedrasheed201]

How do you make this ozone generator please

[@kasraeskandari9351]

can you please start putting the full part list in the description of you videos. what is the watt of those resistor and voltage of 2.2nf and 10nf capacitors? number of turns around that ferrite core and wire gage. also what is the wire gage of the primary winding of the transformer. with these informations we could actually reveres engineer it. thanks .

[@MostlyInteresting]

These really are intended as components for replacements in existing high powered ozone generators or to build your own around. Yep they do need a fan. To move the ozone around about the room. They should clearly state that these things are intended as replacement parts. That I suppose you could DIY around.

[@davidadams421]

Very interesting. Would be good to see that circuit operating in a circuit simulator.

[@СергейНюков]

Hi, friend. I watched your video but your subtitles are turned off and I don’t quite understand your language. Therefore, I have a question - my ozonizer worked for 1 minute, then both transistors and the output winding of the transformer burned out. I changed the transistors. But the transformer is filled with resin. A question for you: is it possible to replace this transformer with anything? Maybe a transformer from a CRT monitor or TV (which has a kinescope)? or what else can be used? So that he can fit into this box? Thank you, I'm waiting for your answer.

[@bigclivedotcom]

Some use an electronic neon sign transformer. These power supplies supplied with them are not reliable.

[@СергейНюков]

Thanks! Could you send me a link to such an electronic transformer? Google doesn't find it for me ( And another question - if I don’t find such a transformer, I can wind it myself. Can you tell me what voltage this device has on the secondary winding? As I understand it, if the circuit contains voltage rectification (diode bridge), then it should be a pulse transformer? Is it possible to use this from a computer power supply?@@bigclivedotcom

[@v1ncend]

Is this safe for a room, if i secure this generator ? Is ozone safe ?

[@bigclivedotcom]

This type of module would be used to sterilise an unoccupied room. Usually as part of a unit with a case and fan.

[@jafe.ribeiro]

Why are some ceramic plates soldered at two points and some only at one point?

[@rishanranatunga4851]

Try to use Rosin when you troubling with soldering. DIAC is not triggering from zero Volt.hope you have explanation about higher voltage biasing transistor behaviour!

[@AW-Services]

I brought a Chineseium ozone generator yesterday with this cheap HV unit in it. Opened the cardboard delivery box, and a piece of wire fell out of the enclosure. The combined switched IEC inlet was potted with silicone, and what they called earth bonding to chassis was a blue neutral wire that was extremely dangerously spot welded and glued to the stainless steel enclosure

[@bigclivedotcom]

They often fail to follow any wiring colour standard. I'm surprised the earth was connected at all. If it's a fused plug, check the fuse is even in circuit.

[@AW-Services]

@bigclivedotcom used my own IEC lead with a real bussmann 3a fuse in it. Checked continuity to ground and chassis to ensure i didn't get stung

You can strip the insulating paint off using HCl. It will continue to work without the coating and it's easier to start without it.
