Ozone Solutions has recently added a new Ozone Generator to our rental line. This is an exciting addition, as this Ozone Generator produces 150 g/hr of ozone from oxygen.
The Water Cooled TG-150 is an extremely efficient and versatile Ozone Generator offering ozone effective concentrations up to 10% by weight. At an oxygen flow rate of only 15 SCFH the TG-150 will produce 55 g/hr of ozone. At an oxygen flow rate of 20 SCFH the TG-150 will produce 70 g/hr of ozone. Check out the entire TG-150 performance data here.
For a complete package, Ozone Solutions also rents the oxygen concentrators necessary to produce ozone from this Ozone Generator.
Our Ozone Research page received four new papers today! These four papers are all complete research papers that were written specifically for, or by, Ozone Solutions. See ozone research.
These papers are a great addition to our research page. The first paper is a paper on Ozone and ground beef. This paper was presented at the recent International Ozone Association Conference in, Bellevue, WA. This paper covers the potential use of using ozone gas to reduce E.coli in ground beef.
The third paper is my personal favorite. That may be due to my personal involvement, however it is more likely due to the great results is showed. This paper shows the relationship of ozone concentration, and contact time against E.coli bacteria. In this paper we discovered that only 2.0 ppm of ozone for one second of contact time is very effective at achieving a great reduction in E.coli bacteria.
We were asked to provide the ozone production performance of the OZV-8 Ozone Generator equipped with the 10-position switch. I prepared an extensive performance chart for this customer showing the ozone output at each switch setting. I thought this chart was worthy of sharing.
It is interesting that the OZV-8 Ozone Generator produces ozone concentrations up to 4.77% by weight at 1 LPM. This is a great ozone concentration for this Ozone Generator. However, the overall ozone production with the OZV-8 peaks out at just over 8.5 g/hr of ozone. It is evident that higher oxygen flows will not improve ozone output. It was impressive to see how linear the ozone output was across each of the switch settings at each flow rate.
For more information on the OZV-8 Ozone Generator see the web-page here. For additional Ozone Generators see our entire Ozone Generator product line. If you have any questions about using the OZV-8 or any other Ozone Generators please call our application engineers today.
Ozone Trailers are built for Groundwater Remediation needs. The mobility, security, and simplicity of these systems are very useful for temporary remediation sites.
Ozone Solutions builds Ozone Remediation Trailers from the ground up. I thought it might be fun to show how this progresses!
Ozone Solutions has trailers custom built by, K&O Manufacturing, right here in Hull, IA. Using a local manufacturer allows a great deal of flexibility in our construction, and a higher quality end product for the customer.
These trailers have vents, an air conditioner, and many internal brackets built into the trailer during assembly. This allows the trailer to be painted after these holes are cut. These pictures show how the trailer arrives to Ozone Solutions.
The inside of the trailer is painted steel construction ready for assembly. There are braces installed for the divider wall, and vent holes cut in the back.
Looking in to the front door of the trailer. Plywood is now installed on the walls with insulation between the plywood and steel exterior. An insulated divider wall is also installed between the front and rear of the trailer. The roof is insulated and lined, with an air conditioner installed in the roof to cool all controls and ozone generating equipment.
Wiring is completed inside the trailer. This is a big task, however working inside a trailer allows great flexibility for the customer and for us to customize all controls for the specific application.
In the rear of the trailer, the Air Conditioner, Oxygen Concentrator, Oxygen Tank, and Air Dryer are installed.
The Ozone Generators are installed in the front of the trailer. The front of the trailer is divided from the rear of the trailer to keep the Ozone Generators, and other control equipment cool, clean, and dust free.

We are commonly asked how to measure output or verify that an Ozone Generator produces the amount of ozone the manufacture claims. This tech sheet will cover how to measure the output of your high concentration Ozone Generator.
hour (g/hr), also known as ozone output. The ozone measurement instrument will read percent by weight (%), or grams per meter cubed (g/m3), also known as ozone concentration. To mathematically determine the g/hr (ozone output) from % by weight, or g/m3 (ozone concentration) you will need to determine the flow rate of the Ozone Generator in liters per minute (LPM). The calculations to use when you have determined the gas flow rate and concentration are below:
From percent by weight using oxygen as a feed gas:
Ozone Output (g/hr) =(( LPM x 0.001) x 60) x(14.3 x % by weight)
From percent by weight using dry air as a feed gas:
Ozone Output (g/hr) =(( LPM x 0.001) x 60) x(12.8 x % by weight)
From g/m3:
Ozone Output (g/hr) = ((LPM x 60) x 0.001) x g/m3
Another resource we offer is a handy online calculator. Just enter your flow and concentration values and we do the work!
When using percent by weight to measure ozone concentration, the calculation to determine ozone output is different because the density of the gas is different. Due to the difference in the density of the gas, there are separate conversion formulas used to determine the output of an Ozone Generator (as shown above).
Ozone Measurement Device
A related question is which ozone measurement device should be used to facilitate these measurements. The short answer is, only a high concentration ozone analyzer. Note that the units of measure used are percent by weight and g/m3. This is due to the high concentrations of ozone produced by most Ozone Generators. We are also asked why parts per million (ppm) is not used as a unit of measure. Let me provide a quick example using a very small Ozone Generator.
An Ozone Generator producing 2 g/hr ozone from 10 LPM of air would produce 0.26% ozone concentration.
2 g/hr = ((10 LPM x 0.001) x 60) x (12.8 x 0.26% by weight)
At only 2 g/hr of ozone output the ppm value is already 1573 ppm. The parts per million (ppm) unit of measure is just not conducive to these calculations. Therefore it is rarely, if ever, used when calculating generator output.
The high concentrations that are created limit the number of ozone measurement devices that can be used, which is why the process is restricted to high concentration UV ozone analyzers.
The diagram below shows an example of a system setup to measure the output of an Ozone Generator.
Components Needed:
Mass flow meter will measure overall gas flow accurately for a flow measurement.
0 – 2 LPM Flow Meter will regulate and measure gas flow through the ozone analyzer.
Ozone Analyzer will measure the ozone concentration in % by weight, or g/m3.
Ozone Destruct Unit will convert ozone back to oxygen to safely be vented into the air.
Other Important Considerations:
When choosing an Ozone Analyzer, ensure that the analyzer you are purchasing operates within the range that you will be operating within. Some Ozone Analyzers are limited to low ranges only, so ensure that you choose a device capable of reading a higher concentration of ozone than you will ever need to measure.
Also ensure that the analyzer you are purchasing will measure ozone concentration using the units of measure that you desire. If choosing an analyzer that measure ozone in percent (%) by weight, be sure to specify whether you are using oxygen or dry air gas. Some analyzers may be only factory configurable and cannot be configured by the user.
Gas flow is a very critical component of the calculations used to measure ozone output. A small deviation in actual flow measurement will result in a large error in the resulting ozone output figure. Since this is such an important value, we recommend using a high quality Mass Flow Meter to measure the total gas flow entering the Ozone Generator. A Mass Flow Meter will measure total gas flow. This measurement is also pressure compensated to eliminate that potential variable. Using the Mass Flow Meter prior to the Ozone Generator will remove the possibility of ozone corroding the delicate components inside the Mass Flow Meter.
Most high concentration Ozone Analyzers will only require a very small gas flow rate. This will require a small flow meter to regulate and measure that gas flow. An advantage of this small flow rate is that the Ozone Analyzer could be used as an on-line measurement device. If the Ozone Generator uses a gas flow rate of 20 LPM and the analyzer will only consume 1 LPM for accurate measurement, this setup only requires a 5% slipstream of the ozone gas.
For questions on how to measure the output of your ozone generator, or for information on the products you may need contact our application engineers for more information. We cal also perform in-house testing of ozone generators to provide 3rd party validation for your ozone generator output measurements.
Just recently, we have put new pressure regulators on our website. They are Ozone compatible and corrosion resistant. With it’s stainless steel body, teflon seals, and viton o-rings, it is sure to last quite a long time. With pressure ranges going all the way up to 100 psi, and bursting pressure at 500 psi, there are useful in most situations.
As a company that manufactures industrial use ozone generating systems, we use these pressure regulators on all systems that require one. They have many more uses though other than putting them in an ozone generating system. They can be used in most situations that would require having a corrosion resistant regulator, such as harsh chemicals or an unpredictable weather setting.
This customer stores and packages various spices in a large warehouse that is near houses, a school, even a busy roadway. This was leading to lower quality of life, and lower property values in the neighboring community.
Warehouse Location
After successfully installing the ozone system within the air space inside the warehouse odors were reduced inside of the building, leaving almost no odor escaping outside. This drastic reduction in odor was a huge success. Not only is the odor in the community lower, the employees have a better place to work.
