Building Your Own Ozone Chamber

Ozone Chambers

There are many different options for ozone chambers. Many chambers will have an integrated turnkey system where ozone will be produced from the chamber itself. However, if you are looking for a more cost-effective option, or, you already have a chamber, room, or enclosure you want to control ozone levels inside of, building your own ozone chamber is a great alternative. This article will go over the different products necessary for assembling an ozone chamber, as well as some different specifications to take note of to make sure you get the products that will best fit your applications.

Here we can see the inside of one of our chambers, with an internal fan to ensure ozone is being properly circulated.

Components

Ozone Generator – The most important component is the ozone generator to produce ozone for your ozone chamber!

Choose the ozone generator size and output, normally rated in g/hr (grams per hour), based upon the following factors

  • Size of your ozone chamber – larger chamber = more ozone demand
  • Level of ozone required inside your chamber, normally measured in ppm. Higher ozone levels desired will require larger ozone generators
  • Temperature of the chamber – higher temperatures will increase the ozone half-life and demand more ozone
  • Organic loading in the chamber – material in the chamber that will consume ozone due to natural organic loading should be considered

See our selection of ozone generators HERE.

Ozone Monitor – An ozone monitor is required to measure ozone in the chamber and switch a relay in the ozone monitor to control the ozone levels. The ozone monitor will be located outside of the chamber with either a remote sensor, or small Teflon tubing inlet port placed inside the chamber to detect ozone levels.

Two main options are available to measure ozone

  • UV based ozone analyzer – pulls a sample of ozone gas from the chamber, passes through a UV lamp and measures ozone by determining how much ozone is absorbed by the UV lamp. This method allows for ozone detection accuracy up to 1%, and measurements from 0.001 ppm up to 10,000 ppm and even higher.
  • Remote mount sensor based ozone monitor – an ozone sensor is placed inside the chamber and wired to the main ozone monitor placed outside the chamber. This method allows for ozone detection accuracy ranging from 5 – 20% and measurement from 0.01 ppm up to 200 ppm reliably. These sensors are a lower price point than the UV analyzer and are normally used when cost is a concern.

The ozone measurement device must have a built-in relay that can be wired to the RCB-1 relay box that will turn the ozone generator ON/OFF. This relay should be easy to set and alter if necessary.

Relay Control – The relay control box has three components to it necessary for creating the ozone chamber. By looking at the image above, we can see the three different cords coming from the bottom of it (smaller white box on the far right side of the above image). Its far-left cord is simply connected to a wall outlet to supply power. The thinner, middle cord connects to the ozone monitor (far left, white/blue item) and then its far-right cord connects to the ozone generators power cord, and supplies power to the ozone generator. When it comes to which relay control box to use, Oxidation Technologies offers the RCB-1.

Ambient Ozone Sensor – We also highly recommend using either the C-30ZX Ozone Monitor, or the SM-70 Ozone Monitor to read for ozone in the air. This ensures that your environment is safe and free of ozone. Both of these monitors offer accurate ozone readings, compact designs, and low maintenance making them easy to use as well as extremely efficient.

How It Works

Looking at the diagrams below, ‘DIAGRAM 1’ shows the set-up for a custom ozone chamber when you are using one of the bench mount ozone analyzers, and then ‘DIAGRAM 2’ is showing the same basic scheme, but with a remote ozone sensor. However, the basic procedures are going to be the same, independent of which monitor set-up you decide to go with.

Following the diagrams below, we can see the procedures that will occur when your custom ozone chamber is working properly. First, using dry-air or oxygen as the feed-gas, your ozone generator will begin producing ozone for the chamber. Then, the ozone analyzer (or remote sensor) will read how much, in PPM, ozone is present in the chamber. The reading from the ozone analyzer will then be transferred to the RCB-1 relay control. Based on the reading given to the RCB-1, it will transfer a signal to the ozone generator to either continue producing ozone for the chamber, or to stop the ozone production.

Ozone Chamber demonstrated breaking down rubber products

We just finished a quick video on the use of our CH-3 Ozone Chamber in use.  A few latex gloves and rubber bands were exposed to ozone in this video for a demonstration.

Ozone set-point of 800 ppm was used.  Watch how quick we achieve 800 ppm and how well we maintain 800 ppm toward the end of the video.   Should you have a need for an ozone exposure chamber, or any ozone testing services, let us know.  We would be glad to find a solution that fits your needs.

Ozone Exposure Chamber Demonstration

We have a great video (see below) of our CH-1 ozone chamber in action.  This video shows the operation of the CH-1 ozone chamber, but also is a great demonstration of the oxidizing power of ozone and how different materials react to ozone.

 

A latex glove is on the right while a silicone glove is on the left.  On the bottom, there is a glove stretched over a roll.  On the top, the glove is simply hanging from a wire.  It is clear the latex glove is oxidized much faster.  However, it is important to note that silicone is also not completely ozone resistant.
