High power ozone generator teardown with schematic 

I like the smell of ozone. It's really fresh, like when there's a strong storm close by that smells of ozone. It's always a great time to go outside with a metal rod and collect electrons for later use.

Clive:"i can hear the buzz" Microphone: *bbbbbbbbbbBBBBBBBBBBBBBRRRRRRRRZZZZZZ*

My household uses Big Clive videos to play a game. In this game,We attempt to say the names of every component BEFORE Big Clive. It's hilarious.

Watching this stuff never gets old for me. I remember as a kid taking random stuff apart but ultimately being baffled by this or that. These journeys are way better because I have a guide! :D

"Is this thing holding a charge?" Then he sticks his fingers on it, to find out.

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.

I have one exactly like that, it works fine after I installed it inside a big steel case for a server power supply. Conveniently it already has the fans to run air through.

BigClive - one of the few people who would be excited to buy a broken product!

Black coating is most likely glaze (possibly quartz based) and solder is most likely zinc or even ZAMAK based solder. at these power levels you can get to temperatures that would soften even normal (soda-lime) glass.

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.

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

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 :)

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

Screw electrical standards I have one of them and their powerful as hell

There are 4 types of ceramic plate used on this generator, 5g/6g/7g and 8g respectively. You can see the pattern on the plate. The one Clive is testing used four 6g plates. Two plates back to back to form a double sided layer, and two layers are used totally. item.taobao.com/item.htm?spm=a230r.1.14.35.5e473df9MVuSHU&id=630935221974&ns=1&abbucket=12#detail

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.

I used 2 of these and have made an ozone generator using stainless steel box(by bending sheets) and fan. Sterlizing all the parcels for covid, it works perfectly. They produce 48gm ozone per hour.

I love how the screws that hold the plates down are wall screws.

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

*Clive: **_"I'm Pro-Ozone."_* Sir, you are *_PRO-ZONE._* {I will see myself to the door now...🤭}

Superb explanation of this simple ( not to me😊) circuit.

"I'm wondering if this is the same circuitry used in electronic neon power supplies." - probably lmao

Circuit says: "You will only be positive." and "I will use resistance to trade power for volts and amps."

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

13:25 scream laughed on that one, then tipped over and farted!..

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?

You should black mail them in a possible class action suite and make them supply your channel with an ultimate set of tools lmfao.

Hello. The diode in parallel was missing from the 2n2 capacitor

Did you manage to fix it then?

It has been found in experiments using the apparatus and methods of the invention that exposure of HIV-infected blood to an ozone-oxygen mixture having an ozone concentration of no more than about 27 .mu.g/ml, or 2.0% by weight, and a surface pressure of about 2.2 psi, for a time period of only about sixteen seconds, resulted in inactivation of up to approximately 99% of the HIV, with no deleterious effect on cellular metabolism or DNA replication. The invention is particularly adapted for the extra-corporeal treatment of human blood in a continuous process, wherein blood is withdrawn from a patient, circulated through the treatment apparatus of the invention and returned to the patient. Although the specific conditions of the treatment process may vary from patient to patient, depending upon the general health of the patient and the condition of the blood, satisfactory results are generally obtained when the blood is caused to flow through the gas-liquid contact apparatus at a flow rate of about 65 ml/min, typically achieved when the gas-liquid contact apparatus is inclined at an angle of about 27 DEG to the horizontal, and the concentration of ozone in the ozone-oxygen mixture is no more than about 27 .mu.g/ml and is at a surface pressure of about 2.2 psig. The gas-liquid contact apparatus of the invention is non-foaming, whereby it is not necessary to reconstitute the blood after treatment, and treatment with the apparatus of the invention is virtually free of mechanical damage to blood components, especially in view of the variable onclusion pumps used to pump blood through the apparatus. Moreover, quick-connect/disconnect fittings are used to attach blood lines to the apparatus, whereby all components which might be contaminated with infected blood can be quickly and easily replaced between treatments, so that more treatments can be effected in a shorter amount of time than with conventional apparatus. The invention also provides means for detecting and proportionately adjusting blood flow rate and ozone concentration. Thus, if restriction to flow should occur, a flow sensor detects the reduction in flow and proportionately reduces the drive to the high and low frequency generators to thereby reduce the concentration of ozone.

Hello Clive Sir! I know this vid is 2yrs old but I'm going to ask you for simplicity sake if you could post a link or reference me and others to a breadboard schematic/diagram/layout where I can put it together initially and replace components very simply when they expire/burn out. my soldering skills are less that stellar. I would appreciate this simple circuit with needed components list (I just bought this exact unit in the 110V flavor for US voltage) and there ratings to clone this for personal use only. I've been using corona discharge ozone generators for most of my adult life but there getting expensive buying the 200 dollar units that don't last, so, Maybe you have something I could use to whip up a couple of these on breadboards. Thank you in advance. p.s. love your videos.

does ozone harm pet bottles? I am thinking of using the ozone generator in room with some pet bottles holding liquids, is there a risk that bottles might start leaking?

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.

"Professional DIY" erm...

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.

“Is it a good idea? Nope. Am I gonna do it anyway? Yes.” Story of my life.

It was probably shipped air-mail. That's when it flies through the air into the shipping bin.

That thing sounds like a whole hive of angry pixies while it's on.

Ah yes, the classic method of checking if something has a charge by tapping it with your fingers :)

Broken on arrival. 1000s of volts hanging in the breeze.Gasses its operator. This belongs on Clive's affiliate page·

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.

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!)

love that sizzle sound at 4:37 reminds me of when Big Clive cooked those sausages in that mains cooker

That looks like the kind of thing you'd mount inside an HVAC system to treat the air for an entire building.

Oh Boi I have a great idea for a collaboration: could you help Explosions&Fire to make an efficient Ozone Generator for Chemistry purposes.

1:53: That quote sums up this channel. "Is this a good idea? No. Am I going to do it anyways? Yes."

I've been using O3 for refreshing my house for years. My first generator involved a 2 kilo neon transformer, metal windows screen and a Prego sauce jar. Ghetto as, but it really worked. A timer is a must. O3 is not safe for pets and people.

Corona discharge somehow has quite a different meaning on 2020

The big question is: Will it carbonate?

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

You are a big reason I got an Ozone generator. And I have learned a lot about resistors, bridge rectifiers, and alot about how led lights work and how lighting was done in the past.

About 2 years ago I assembled the exact same unit in a small wooden box with a fan and timer and I do use it from time to time to sterilise rooms in my house. A great Covid killer!

That thing sounds like walking under supergrid pylons on a foggy morning, just loud scary buzzing!!! :S

That thing sounds almost terrifying like a tesla coil spark gap

When I heard that buzzing I had the urge to laugh maniacally and yell IT'S ALIVE!!😂😂

I have a video with a 12v one of these - you can easily modulate its output with the voltage, .. ended up at 10v for a super minimal output level

Me: Wow that thing sounds horrible. Me, two seconds later: I kind of want 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've had two of these and one of them was broken from the box. Most terrifying chinese things I've ever had. To be fair one of them did work for a while.

"Are you sitting comfortably? Then, I shall begin."

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

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...!🚫

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.

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

OMG I was laughing out loud when you turned it on I swear I could smell the ozone

When I want to generate ozone, I run my 60 year old Lionel trains.

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.

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.

Corona Kills Corona...go figure :-/

i like how ya draw that "lazy rectifier" there's no mistaking what it represents. which is always a plus in my book.

My first job in 1974 at Mullard Research labs was screen printing conductive inks on ceramic substrate material. The ink was fired like a pottery glaze at high temperature.

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.

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

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.

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

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 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.

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

So I'm at a pumps and flow meter state training class yesterday, and these Flow meters are battery powered, lithium. But you can't recharge them, im like i can fix that tp4056. You have to clean the probes every 3 to 6 months and get up to 2 years of life out of a battery there answers is take it out throw it away. SMH I'm like while your standing there cleaning the probes charge the "bat tree" (vicegripgarage).

You know that breathing ozone is unhealthy, right? :)

Would love to see a working one of these that is actually incorporated into a finished project. Be great if you build something like that

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.

i just was waiting for you to test those ozon generators

those aren't quartz chips, those are the ground-up bones of children who worked in chinese factories

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.

Wire insulation brought to you by the makers of Twizzlers.

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

Found one with 2x3.5g plates that seems to have a socket to facilitate replacing the plates and spares available on AliExpress. Ordered and fingers crossed it'll survive shipping - thanks for the review!

4:24 OH GOD! That is harcore!

Most common home ozone generator perhaps the laser printer?

I have adopted the "lazy rectifier" symbol - it's just so much neater than the usual one.

i have one similar looking but for 110VAC, its got a different plate design. bought it for 30$ CAD recently i burned my car (interior) and i am about to gas it with ozone to remove the cancer smell. mine works perfectly, it glow blue and really emit tons of ozone. i added a industrial timer 0-5mins on it so i can just plug it and go away.

Great video, thank you Clive! With a huge SAFETY WARNING and DO NOT TRY THIS AT HOME disclaimer, do you think that it would be hypothetically possible to use the HV output of this to do fractal wood burning? Cheers, Chris 👍

I wonder if doubling the plates doubles power consumption and ozone production.

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

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

i was looking on Amazon for an ozone generator and I saw a '5000mg' box with a timer and handle and upon closer inspection of the picture something behind the grille on the front looked suspiciously like the device you have here ;)

I prefer to get my ozone the old fashioned way. By playing with old model train engines. Imagine how powerful it would have been if it wasn't broke.

Big Clive definitely would have conducted experiments with 'The Demon Core' by hand, cited by "This probably isn't a good idea, but I'm going to do it anyway" :'-) God bless him.
