The Safe Way to Use Ozone Generators

When it comes to ozone generators, choosing the right model is important. You need to figure out the specific needs of your space to choose a product that provides the right amount of concentration and features. If you're confused about choosing the right product for your home or commercial space, we are here to help!

We have a team of experts to help you understand the right way of using an ozone generator. Our experts will also guide you to choose the right product for your residential, commercial, or industrial application. When used correctly, ozone generators don't cause harm and help in providing you with a clean and healthy living space.

We always recommend using an ozone generator in unoccupied spaces. However, if your place is occupied with people or pets, make sure the area is properly ventilated and the generator is running on low settings. Ozone generators are similar to air purifiers that have multiple applications.

Our products are effective in removing many disease-causing germs and bacteria by attacking the contaminants at the molecular level. You can also use an ozone generator to remove lingering smells from tobacco smoke. So, if you're concerned about safety, remember that choosing the right product and using it correctly determines safety.

Are you concerned about using an Ozone machine near your family or co-workers? Perhaps you've been told ozone is dangerous, but yet you hear others are having great success using it.

You need to know.

Ozone is like many other essentials in life. A little is good, a lot is not. Too much food can make you overweight, too much water can cause drowning, and taking too much of a life-saving medication can make you very ill. At high concentrations ozone can cause chest pain, coughing, shortness of breath, and throat irritation.

Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections. People vary widely in their susceptibility to ozone. Therefore, you should only run ozone machines on very low settings, in well ventilated spaces, if people and pets are present.

So to use ozone safely, consider what problem, or problems you need to treat with ozone.

Are you looking to merely sanitize the air you breath, get rid of cooking odors, or remove the smell of stale tobacco in a space which you occupy on a regular basis, like your home, office, or vehicle?

If so, Ozone generators can be used in these spaces while they are occupied, only as long the ozone concentration remains below the safe level specified by OSHA or the EPA.

Typically this can be accomplished with an inexpensive machine like our DC-12.

But if larger concentrations of Ozone are required, it can still be a highly effective solution , but that amount of ozone needs to be produced in an area while it is not occupied by people, pets, or plants.

If you want the safest way to use ozone generators, just run them when the space is unoccupied. Utilize the timers, available on many of our units, to switch on our ozone generators while you are out of the building and shut them off an hour or so before you return so the ozone has time to safely dissipate (turn back into oxygen) prior to reoccupying the space.

In your vehicle you can run it for 2-3 hours during the night and start your day with a clean, bacteria free ride to work.

You may also safely operate our machines on their higher settings in an adjacent room as long as the door is shut, or another barrier (plastic sheet) is employed between the occupied space and the room being treated. Generating ozone in the basement while you occupy the upper floors, is generally not a problem as ozone is heavier than air so it will remain down it the basement.

Ozone generators are ideal for certain specific applications such as:

• Killing mold
• Killing mildew
• Killing bacteria
• Getting rid of odors

Killing mold, mildew and other germs takes high concentrations of ozone so that should only be done when a room is unoccupied. Mold is also much tougher to treat than common odors, so plan on running a properly sized ozone generator for at least 30 hours in each room being treated.

The ozone concentration needed to kill mold (shock treatment) is well beyond the level that is safe to breathe. It is similar to fumigating a room in your house for bugs. You wouldn't want to stay in the room breathing those chemicals. Luckily, ozone doesn't smell as bad and doesn't linger as long as those bug killers.

Ozone generators do not remove dust particles from the air, filter the air, or remove cigarette smoke. They do remove smoke odor lingering in the carpet or on the walls and furniture ' either from tobacco products or from a fire.

Ozone generators work well in removing odors from automobiles, boats and recreational vehicles. They do not mask odors; ozone generators destroy odors, never to return.

There are two proven ways to get rid of mold and mildew in your home or office.

1. One is to remove all of the mold-contaminated material in the building.

    

   A reputable mold remediation company should be employed for this job as it involves handling some very nasty material and should be performed by personnel protected with hazardous material gear. If done properly, it is the most thorough method, but it is costly, usually $8,000 and up.
2. Using an ozone generator is the other proven method that is much less expensive (85 to 90% less)!

    

   A

    

   sufficiently high

    

   concentration of ozone will kill airborne mold (the most dangerous type and the most likely to end up in your lungs).
3. But' it is important to use a high output ozone machine (several thousands of milligrams per hour [mgph] and these output ratings must be based on using normal air as the source gas ' not pure oxygen.

Ozone generators will also kill the surface mold on any material it contacts.

Ozone is like air, if air can reach the mold, ozone can reach the mold, and kill it, permanently. Neither air nor ozone can penetrate dry wall, wood, or other non-porous building products. It is difficult for Ozone to get into the padding under carpets, or inside stuffed furniture.

So remember, killing mold is a serious issue and the higher the ozone output the better; but if your budget dictates a bare bones approach, here is an powerful mold killer, and it is on sale right now.

How to choose ozone generator

How to choose an ozone generator must know the evaluation index of the ozone generator. Generally, the most basic indicators for evaluating an ozone generator are: ozone production, ozone concentration, reliability, service life, convenient and beautiful work, power consumption, etc. The power of ozone generators used in pharmaceutical factories is relatively small, and power consumption is a secondary condition.

Basic knowledge

In order to better choose the ozone generator, first introduce a little basic knowledge about ozone and ozone generator.
Ozone concentration unit:

• Nominal ozone concentration by volume percentage concentration for international traffic. The ozone concentration of 1% air source is 12.9mg / L. The ozone concentration at 1% oxygen is 14.3mg / L.
• The sanitation and disinfection industry is accustomed to use ppm as the unit. That is one part per million. For ozone in the air, 1ppm = 2.14mg / M3.

1. Ozone concentration:

The ozone concentration at the outlet of the ozone generator. Generally, the unit is ppm or mg / L. 1ppm = 0.mg / L.
Surface discharge electrode: The outlet concentration of the ozone generator is low, generally 60-80ppm (generally less than 20PPM in air source).
Gap discharge electrode: The outlet concentration of the ozone generator is high, generally -ppm.

2. The form of electrode discharge:

• Surface discharge type electrode (that is, glass tube is generally used as dielectric material, in-pipe ventilation and out-tube ventilation):
  One is the aluminum mesh with the inner electrode attached to the inner wall of the glass tube, and the outer electrode is a conductive coating such as graphite. There is gas in the tube. The other is to fill the glass tube with nitrogen and a small amount
  Argon or krypton gas, the inflation pressure is thousands of pa, the inner electrode is a nickel wire, and the outer electrode is an aluminum mesh sleeved on the outer wall of the glass tube. Gas passes outside the tube.
• For these two electrodes, only a small amount of gas flowing along the wall of the tube participates in the discharge, and the output is low. The accumulation of ozone output will gradually decrease with the use of time. At the same time, the reliability is poor,
  Short life. (- hours) But the cost is low, the production is simple, and a few people can assemble and produce. Generally there is no perfect inspection equipment.
• Gap discharge electrode:
  One is to use a ceramic tube as the dielectric material, the outer wall is plated with a metal coating for the outer electrode, the metal tube is for the inner electrode, and the tube is cooled by water. Oxygen from the gap between the inner and outer electrodes
  Pass in the gap. The other is a plate-type ceramic dielectric gap discharge electrode. Air cooling or water cooling, oxygen passes through the gap between the two electrodes.
  For these two electrodes, the gas is discharged through the gap between the electrodes, with high output, high reliability and long life (over 30,000 hours). Ozone production and equipment
  The use time is irrelevant, but the cost is high, it requires finishing, complicated assembly and debugging, and requires factory production. Have perfect testing equipment.

3. Air source

Most of the surface discharge type ozone generators use ambient air as the air source, which produces more nitrogen oxides. After the nitrogen oxides are in contact with the humidified air in the air duct, it is very easy
Sour gas (nitric acid) is generated. Decreasing the electrode life has an adverse impact on the environment.
Most of the gap discharge ozone generators use an oxygen source or a dry air source, which produces less nitrogen oxides, has a long electrode life, and is not harmful to the environment
influences. The oxygen source can be bottled oxygen, or an oxygen generator or dryer.

4. Power supply

The power supply is divided into power frequency, intermediate frequency, and high frequency. The power supply frequency is high and the number of discharges is high, the efficiency is high and the power consumption is saved, and the electrode volume is small.

5. Quality classification

· Low-grade products-built-in air source products-surface discharge type-industrial frequency power supply-poor protection function-installation requires air conditioning cooperation.
· Mid-end products-external air source products-gap discharge-with air dryer-air compressor-protection capability-installation has nothing to do with air conditioning.
· High-end products-external is an oxygen source product-gap discharge-bottled oxygen or oxygen generator-strong protection ability-installation has nothing to do with air conditioning.

Test results of different electrodes

In order to verify the relationship between the nature of the gas source (oxygen source, air source) and the output, and the relationship between the different discharge forms (creep discharge \ gap discharge) and the output, the author, with the help of a research institute, inflated the tubular ozone discharge The electrodes, the tubular ozone electrode with non-inflatable surface discharge, the tubular ozone electrode with gap discharge, and the plate ozone electrode with gap discharge were tested. The results are as follows:
In order to unify the test conditions, the author tested the following four electrodes using an oxygen source, and the output was the highest output of these four electrodes.

1.'29 × 265mm non-inflatable glass along-surface discharge tube ozone electrode. (The oldest electrode form)

• Electrode structure: glass tube electrode, the inner electrode is an aluminum mesh attached to the inner wall of the glass tube. The outer electrode is graphite coated. There is gas in the tube.
• Working principle: The transformer boosts the mains electricity to high voltage electricity, powers the electrodes, and generates ozone between the inner electrode and the inner wall of the glass tube. Pass oxygen into the discharge tube,
  After energizing, measure the gas volume and ozone concentration.
• Test Results:
  Oxygen 2M3-4M3 / h, the highest ozone concentration is 50-70ppm; the calculation result is 3M3 / h × .60ppm × .2.14mg / m3 = 385mg = 0.39g / h per tube
  (The ozone concentration in the air is 1ppm = 2.14mg / m3)
  The surface area of ''this tube is: 0.029M × 3.14 × .265M = 0.024M2 The discharge tube required per square meter of discharge area is: 1M2 ÷ 0.024m2 = 41.
• Therefore, 41 such electrodes can be obtained, which can produce 15.99 grams of ozone per hour using an oxygen source. If using a dried air source can produce
  5.33 grams of ozone. This type of discharge tube also does not comply with the provisions of CJ / T.1-94, Article 5.3.2, the ozone output per square meter of discharge area should be greater than 30 grams.

2. Ø29 × 265 mm inflatable glass tube discharges ozone electrode along the surface. (Improved electrode, good looking during discharge, also known as discharge lamp, limited production increase)

• Electrode structure: glass tube electrode, filled with nitrogen and a small amount of argon or krypton gas, the inflation pressure is thousands of pa, the inner electrode is a nickel wire, and the outer electrode is sheathed in glass
  Aluminum mesh on the outer wall of the tube.
• Working principle: The transformer boosts the mains electricity to high voltage electricity, powers the electrodes, and generates ozone between the outer electrodes and the glass tube. Put this discharge tube into a closed
  Oxygen is introduced into the UPVC pipe, and the gas volume and ozone concentration are measured after power is supplied.
• Test Results:
  Oxygen 2M3-4M3 / h, the highest ozone concentration is 60-80ppm; the calculation result is 3M3 / h × 70ppm × 2.14mg / m3 = 449mg = 0.45g / h
  (The ozone concentration in the air is 1ppm = 2.14mg / m3)
  The surface area of ''this tube is: 0.029M × 3.14 × .265M = 0.024M2 The number of discharge tubes required per square meter of discharge area is: 1M2 ÷ 0.024m2 = 41.
  Therefore, 41 such electrodes can be obtained, using an oxygen source, which can produce 18.45 grams of ozone per hour. If using a dried air source can produce
  About 6.15 grams of ozone. This type of discharge tube does not comply with the provisions of CJ / T.1-94 5.3.2 The ozone output per square meter of discharge area should be greater than 30 grams.

The CJ / T.1 standard requires dew point for gas source as follows:
5.3.1 The performance test of ozone generator products (including ozone generating power supply) shall be carried out under the following conditions:

A. With air as the air source, the dew point cannot be higher than minus 450C.

In the application of GMP air sterilization, the humidification system of the air conditioner humidifies the intake air. The dew point of the humidified air is much higher than minus 450C, which is generally only slightly lower than room temperature.
Therefore, using the circulating air of the air conditioning unit as the air source does not meet the dew point requirements of the air source of the CJ / T.1 standard.

• The above two types of discharge tube electrodes, even in the case of using an oxygen source, have not yet reached the rated output. If an air source is used, it is even more pitiful.
• The electrode is working under high voltage discharge, and it is not suitable to work in a humid environment. Otherwise, the output will drop significantly.
•  It is not difficult to see through the above test: If the equipment used to calibrate the ozone output with oxygen source, if air is used as the gas source. Its actual ozone output is only calibrated by famous brand
  1/3 of output. That is, the original design was 10ppm dosage, but actually only added 3.3ppm.
• Unfortunately, people who say that ozone sterilization is not as good as formaldehyde use this machine.

B. '41 × 300 mm tubular ceramic dielectric gap discharge electrode.

The ceramic tube is used as the dielectric material, the outer wall is plated with a metal coating for the outer electrode, and the metal tube is the inner electrode, and the tube is cooled by water.
Oxygen passes through the gap between the inner and outer electrodes.
Oxygen is introduced in 0.8M3 / h, and the average ozone concentration is 50g / M3.
Calculation result The output of single tube is 0.8M3 / h × 50g / M3 = 40g / h The surface area of ''this tube is:
0.041M × 3.14 × 0.260M = 0.033M2 The discharge tubes required per square meter of discharge area are: 1M2 ÷ 0.033m2 = 30.
· Therefore, 30 such electrodes can be obtained. Using an oxygen source can produce 1,200 grams of ozone per hour. If an air source is used, it can produce about 400 grams of ozone per hour.
This type of discharge tube is much higher than the provisions of Article 5.3.2 of CJ / T.1-94.

C, 212CM2 plate ceramic dielectric gap discharge electrode.

The electrode is air-cooled. Oxygen is introduced in 0.5M3 / h, and the average ozone concentration is 50mg / L.
Calculation result: the output of a single group is 0.5M3 / h × 50mg / L × = mg = 25g / h
The surface area of ''this board is: 0.021M2, and the discharge board required per square meter of discharge area is: 1M2 ÷ 0.021m2 = 47.6 sets.
· As a result, 47.6 sets of this type of electrode were obtained. Using an oxygen source can produce grams of ozone per hour. If an air source is used, it can produce about 397 grams of ozone per hour.
This type of discharge tube complies with the provisions of Article 5.3.2 of CJ / T.1-94.
With the above test data, you only need to understand the quality of the ozone generator by understanding the type of gas source, discharge electrode form, and power frequency. Even counting a few electrodes can roughly estimate how much ozone is produced.
Then choose the low-grade, medium-grade or high-grade ozone generator according to your needs.

In summary

there is no standard for ozone generator for GMP transformation. In order to regulate the application of ozone in GMP air purification, it is urgent to establish a unified standard for ozone equipment for GMP (Ministry-issued standards or industry standards)
