Product Description

Ceramic Tube Ozone Generator for Air Treatment units O3 tube KHT-15GWOA1

One set includes one ozone tube and one transformer.

Open type transfomer.
Adjustable ozone output.

The ozone tube is newly-developed, double air cooling design, can work 7*24hours only under AIR COOLING. Besides, the electrode inside the tube is improved to change into titanium alloy, this makes the longlife of ozone tubes longer than former tubes.

Ozone Applications

Ozone is a strong oxidant, with instability. Under normal temperature and pressure it is a light blue grass smell of gas. Ozone has efficacy such as disinfection, deodorant, decolonization and preservation. The ozone sterilization is faster than the ultra-violet disinfection, chlorine disinfectants or even 100 or 3000 times faster, and after the use of ozone to oxygen to break down, there is no residue. Therefore, the ozone was hailed as a "green" disinfectant. 

Ozone' s main role is reflected in

(1) The sterilization in the air or water;
(2) Decomposition pesticide residues in fruits and vegetables;
(3) Cold preservation;
(4) Decomposition most of the harmful air decomposition of organic matter, such as: ammonia, nicotine, formaldehyde, xylene, and other harmful substances;
(5) Ozone water suppresses all types of skin disease;
(6) Application in medicine with the analgesic effect;
(7) High concentrations of ozone - oxygen mixture can be injected as treatment of cervical hyperplasia;
(8) Decomposition of the BOD, COD in the sewage, and so on;
(9) Suppress water scale when water heated. Make water activated and improve the taste of water;
(10) Oxide removal of metal ions in water, such as iron, manganese, lead ions. 

(11) The greenhouse vegetable repellent, reducing pesticide use.

The structure drawings of ceramic ozone tubes


1. Narrow discharge gap, high ozone output and concentration, low noise. 

2. High-voltage and high-frequency corona discharge, small size transformer, low consumption rate of electricity. 

3. The ceramic tubes are with low working voltage but high dielectric constant, not easy to be breakdown. 

4. Dielectric materials are made by imported high purity aluminum oxide that are sintered through high temperature, two times high-precision internal and external burnish, thus discharge uniformity. Besides, 316L stainless steel internal electrodes and tightness firmwares make its performance better. The end caps of ozone tube and ozone outlets are made of polytetrafluoroethylene, high-purity corrosion resistant fluorine rubber seal rings, with aluminum alloy external radiator, an very effective way to heat radiation. 

5. Ozone decrease is lower than 5% if work for a long time, while life time is more than 20,000 hours. 

6. Easy to maintain and install.

Attention must be paid to the following

1,The inlet of cooling water should be higher than the ozone tube to ensure the ozone tube is full of cooling and flowing water. 

2,When the ozone generator work, it is necessary to have cooling fans to blow the ozone tube and ozone power supplies. When installing the power supply, please make sure there is 2-3cm high space between its bottom and the fixed board, so that heat on the bottom of the power supply can be radiated quickly. 

3,This is a high voltage product. Do not touch it when it is working. 

4,Usually after ozone sterilization, it needs 20-30 minutes to diffuse ozone before anyone enters. And only when the ozone concentration is or below 0.15ppm, it is permitted to enter. 

5,If you use ozone for water sterilization, please make sure the ozone outlet must be above the water surface. 

6,Please use suitable air dryers when the environment is humid. It will be much better if you equip the oxygen concentrators. If the ozone generator doesn't work because of moisture, please open the ozone tube and take out the ceramic tube, then put the CERAMIC TUBE into an oven or microwave oven(Function Reference : barbecue) for about 20 minutes. After that, please re-install the ceramic tube, the ozone generator will work again. 

7,The ozone output test data is based on 95% pure oxygen feeding and dew point -45 ℃ through the ultraviolet absorption method. Different temperature and humidity in the environment will affect the ozone output and concentration. 

8,When two high voltage wires are very close to each other, especially under moist circumstances or they touch, the wires will make a light and possibly lead that the insulation becomes discoloured even melts. The way to avoid this matter is to keep the two high voltage wires parallel or separate, at least untouched. 

9,Usually when ozone generator is used for test, it will be better if the interval time between two tests is half an hour. It is because the output voltage and start-up electric current is very very high, if it is started up and closed down frequently within several minutes, power supply is possible to be burned due to instant or instantaneous high current. 

10,Deoxidized materials or objects should not be contacted with ozone for a long time in order not to cause damage or corrosion, such as rubber, iron, and copper and so on. The corrosion will accelerate when iron, copper pieces without coating are in the moist.
