That's some good old fashioned pixie wrangling like they did in the old days.

I worked in home restoration (water, fire, mold, and biohazard remediation) and I'm repeatedly amazed at how small super high output ozone generators have become. 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.

Even the regulars here can benefit from your knowledge....repetition makes perfection.

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!)

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 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.

Hey BigClide, thanks for that video. I bought that same Ozone-nator, however mine was advertised as a 12V device. Thanks to you, I opened it up and saw, a 400V Cap, which lead me to belive it was a 230V generator. Hooked it up to mains voltage, ducked for cover, turned it on and it worked. But it suffered the same damage as yours, top plate cracked. Thanks again, have a good one.

Just took delivery of one of these... Featuring the classic black as L and red as N... Can confirm RCD in our consumer unit is functioning correctly...

I have 2 of those mounted on a board with a fan blowing across them, They produce an enormous amount of ozone. On the side of the units they suggest 12g/H, but who know how much they are really producing, all I know is its a lot. For removing cigarette smells from houses or urine smells from old public toilets it does an amazing job.

These things are great. I just recently got one off eBay. I've had it one day. They really kill odors great so far.

I couldn't make heads or tails of this schematic. Thank you for the explanation. It's a clever circuit, very good at what it does. I have one of these ozone generators (albeit it runs on 12V, but I imagine it works largely the same), and it indeed uses a lot of power, some 80W in my case. I imagine I could put it in an old PC PSU case for insulation, fanning and cooling.

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!

i just was waiting for you to test those ozon generators

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. I don't know whether to curse you or thank you for the renewed interest. I think thank you is probably the strongest and most accurate at the moment. Until I land in the snow! 🤣

Thanks for the review. It started at 130 Watts and crept up to above 161 within a few seconds. No doubt if you had left it on much longer it would have gone up in smoke.

Bought a pair of these type a few years ago, have them in a box with a fan. Extremely powerful as a "ozone shock" generator have sanitized more than one car with it. Got a sketchy video on the tube about that.

I've used a portable ozone generator that looks like that but in a case with a fane to kill the odors in rooms and cars. Also works good to kill off mold in basements. Wipes out many bugs as well.

Awesome video my friend!

I've had the same years ago. Works well in the car

I bought the same module about a year and half ago from Amazon for a project (had to return it 3 times too as each one arrived with a busted top ceramic plate) but eventually got one that wasn't cracked. 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.

Crazy how much power they are putting through it - wonder how long you could run it for before it self destructs? More than 5 mins? Wonder what the power consumption levels off at it was still ramping up when you pulled the plug.

The conductive coating is probably metalization. Typically it will be molybdenum and some other metals to form an alloy that can then be deposited on the ceramic.

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.

Wonder if you could regulate these with a simple dimmer? The power factor is almost unity and the current isn't high. Maybe a circuit with a simple relay could be used to regulate them too. Might try an build a PWM triac controller if that would work best.

Hi Clive. I have bought a similar piece a shit from Aliexpress as a complete ozone generator and it worked for 5 seconds and it died...trying to fix it since...hope to get somehow a new transformer since it's the last thing to be replaced..Thanks for your schematic

Just a warning, ozone is VERY dangerous in even moderatly low concentrations. I use mine to help remove the smell when a rodent has died and i cannot retreive the carcass.

The photos seems like I am watching a 3d movie. I also did the Christmas light memory hack and it's working perfectly no more flashing.

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

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.

@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

it is meant to be installed in an air handler plenum

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

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?

​@@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.

I mean they described it as a a DIY device, and it doesn't have a plug on it so I'd imagine it was implied that it needs a fan in an enclosure to be used properly. presumably to build your own ozone generator

@@bigclivedotcom I know that some 'medicinal herb growers' sometimes put a few ozone generators inside their fan ducting to help reduce any unwanted odours. 👍 Given the fact that most of them also steal the electricity, the insane power consumption wouldn't be such a worry 😂

There was a famous(?) article in the magazine of the "Institution of Electrical Engineers" back in the 1950s or 1960s (I believe) entitled "The Killing Fields". This article discussed the apparent statistical correlation between instances of cancer among the general population (of the UK) versus the physical routes of high voltage electrical distribution pylons around England. The article expressed the view, not only that ozone was poisonous, but also that it could induce cancer into living organisms. I don't know whether or not this view of cancer causation was subsequently confirmed, but I understood that the above-mentioned correlation was an accepted fact. For those wishing to pursue this subject, the original article might be available from the library of the "Institution of Engineering and Technology".

It sounds like Flash Gordon's spaceship from the old cinema series.

Thank you.

plates show a condenser effect. As it removed 2 plates, the resonance frequency deteriorated and power consumption increased. If he worked a little more, it would burn. It normally draws power due to 80w. Its approximate frequency is between 15-25 kHz. dielectric plates are broken. There was a short circuit and the power continued to increase

@@jafe.ribeiro Think of plates like capacitors. It connects two parallels in series or different. In this way, it obtains an average value.

The GOOD sellers list these as a replacement plate for the Ozone generators that are in the box with fan and timer. Bad sellers sell them claiming it can be used as it is,which is totally🚫 UNSAFE...!🚫

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.

The advert photograph is correct - all that is left of the end user is couple of hands and a pile of ash.

I put one of these in an old PC PSU case with a small 12V PSU to run the fan. It makes a lot of ozone, but it gets so hot I'm worried about leaving it on for more than a minute or two.

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 .

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!

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.
