Ozone (see What is Ozone?) is a strong oxidant gas that can be used for disinfection and odor removal.Ozone is well-known natural gas with extremely powerful sterilizing ability and it is also the most powerful natural deodorizer known to science. When ozone concentration up to 0.2 PPM or above in air, it can destroy most of toxic fumes, bacteria, algae, fungus, mildew, mold, odor and breaking them into water, carbon dioxide and free oxygen (Click to see this news in details). In most cases, ozone sterilizes air and water that it does not leave any toxic by-products, carcinogenic residues and finally back to oxygen. 

Application description :

Food Preservation  

Ozone has been proven as the best tools to reduce the spoilage of fruit, vegetable and meat by the effective control of mold, fungi and bacteria. Ozone can decompose “ ethylene ”, the gas caused fruit and vegetable ripening. Therefore, once appropriate amount of ozone is applied, the Shelf -Life of food can be prolonged significantly. 

Elimination of odor cross contamination in Freezer House

Ozone is the best de-odor reagent in the world. Nowadays, Ozone has been introduced in all the modern freezer houses as the Standard facility. Ozone can eliminate the odor cross contamination which used to happen inside the freeze house. 

Ozone Against Mould

Mold and Fungi will grow easily in warm and high moisture area and stained the product surface. Paper dishes and cups, cloth and all kinds of kitchen utensil will be possible spoiled by mold stain. Ozone is the smart guard and the best solution to against the mold stain as ozone kills mold effectively. 

Ozone to drive away rats, Cock-roach and other insects

We provide not only the product but also the successful application. Our laboratory and engineering team will assist you to install the system and regularly verify the disinfection performance.

Air Quality Analysis by our Laboratory to determine the total airborne bacteria inside a office

Application areas : 

• Cooling tower for air-conditioning system -- excellent for reducing chemical cost and maintenance. Cost could be cut down over 30%. Not only bacteria killing but also reduce scale forming.  
• Drinking water system -- Effectively kill bacteria, organic and chlorinated compounds. Best solution for improvement water quality. Reduce maintenance service for water tank cleansing.
• Swimming pool -- Ozone can break the organic compounds (e.g. trihalomethane), which can cause cancer and hazardous to human health. Could be used with chlorine disinfection system, largely reduce chemical cost and bad-effect from chlorine solution. 
• Food processing --  Small amount of ozone can extend the storing life for food or fruit. 
• Laundry -- sterilization and cleaning -- Ozone can sterilize bacteria in cold temperature water. It is a good detergent and greatly reduce of chlorine usage and chemical cost. 
•  Aquarium (Fish Tank) water treatment -- Ozone can kill bacteria at water and fishes' surface. It also increases the dissolved oxygen level in water.     

We emphasis on providing completed solution :

• On-site evaluation and installation
• Testing and commissioning
• Monthly monitoring with laboratory analysis. Our laboratory can measure total bacteria count, total coliform, E-coli, chlorine, turbidity, pH, suspended solids, heavy metals, conductivity, alkalinity and so on .... Full analysis report will be submitted to our customers
• Monthly on-site checkup and preventive maintenance 

Many European countries have already switched to use ozone to replace chlorine.
