Combination of the four strongest disinfectants/oxidant agents working together:

1. Germicidal UV-C light
2. Ozone (O3)
3. OH free radicals (hydroxyls)
4. Negative Ions (anions)
Dry Disinfection System
Germicidal UV-C Radiation
Example installation of DDS Module
DSS Modules for ventilation ducts are individually designed for each customer and application. When delivered, the modules are preassembled and ready for installation.
Disinfected air is evenly distributed by ventilation ducts inside the building, keeping the ducts clean and hygienic. The DDS Air Duct model can be fitted inside and outside the ventilation ducts, just behind the air inlet if possible.
• Almost maintenance-free, UV lamps to be replaced
...after 10,000 hours
• Continuous antibacterial protection and improved hygiene
• No chemical compounds and no waste
• Economically effective method of disinfection
• Leaves no harmful residues in food
• Disinfects the air and surfaces
Farming:
- Reduces the risk of infection
- Prevents diseases from spreading between animals
- Eliminates unpleasant smell (cars transporting dead animals)

Car Industry:
- disinfection of car air conditioning systems
- eliminates unpleasant smells (tobacco)

Production, Office Buildings, Residential Buildings, other

• storage of foodstuffs
• sterilization of surfaces
• germicidal, sterilizing and affecting metabolism
• meat
• cheese
• eggs
• beverages
• fruit and vegetables
• elimination and neutralization of unpleasant smells
1- Digitally created image of a bacteria cell
2 - Close-up of ozone molecule coming into contact with bacterial
......wall
3 - Ozone bonds with organic compounds in cell wall
4 - The free radical of ozone breaks bonds in cell walls
5 - Ozone destroys integrity of cell wall and it starts to disintegrate 6 - O3 kills bacteria in a split second and continues oxidation of
......bacteria and released organics
Ozone's impact on bacteria
• Ozone is 50% more efficient in penetrating through bacterial
...membranes than chlorine
• It kills a wide range of bacteria 3000 times faster than chlorine
• Strong disinfectant at low concentration
• Decomposes to oxygen – no waste
• Extends usefulness of many food products
• Eliminates smell, taste and colour
• Easily and economically received at the site
• Easy to detect even at low concentration and safe to use
• FDA-approved for direct contact with food products
Hydroxyl is a safe, efficient, naturally occurring compound. It is present in Earth's atmosphere and removes pollution from the air. Hydroxyls and free hydroxyl radicals occur when the UVC radiation removes the hydrogen atom (H) from the water molecule (H2O) creating negative hydroxyl ions and some hydrogen peroxide (H2O2) which helps to clean the air The process is based on a hydrogen bond created between the hydrogen atom and other atoms. Hydroxyl’s impact on unwelcome organic compounds such as VOC is clear

* VOC - Volatile Organic Compounds
Research results which prove the efficiency of negative ions
• Journal of Food Protection Research carried out in 2001 proved that negative ionization of the air was highly efficient in destroying Salmonella in water and the air

• U.S. Dept. of Agriculture The USDA confirmed that during the research carried out in typically polluted poultry farms it was established that:
• Passing of Salmonella bacteria between chickens fell
...by 98%
• Reduction of Salmonella in the air by 95%
• Reduction of dust and particles in the air by 99%
...in 60 seconds (Summary of research from the USDA website)

• Interaction of ozone and negative air ions to control micro-organisms:

Direct exposure to UVC 254 nm radiation and the proper exposure time deactivate DNA and RNA of microorganisms such as bacteria, viruses, mould spores, yeasts and protozoan, making them sterile and unable to reproduce.
