Grease and odour reduction with UV light and ozone

UV Safe™

Filtration system with UV light and ozone for grease elimination and odour reduction

  • Used in situations with very high purification demands on a professional kitchen’s exhaust air, e.g. to facilitate heat recycling
  • Reduces kitchen odours that can disturb the surroundings
  • Air-cooled electronics and LED display to ensure optimal functionality
  • Extremely easy installation and maintenance
  • The system complies with the most stringent safety requirements

How UV Safe works

UV Safe is a complete system for grease and odour reduction in professional kitchens. The exhaust air is filtered in three stages. First, most of the grease particles are separated in the Cyklotec cyclone filter. Additional filtration and temperature reduction then takes place in a wire mesh filter. Finally, the remaining grease and odours are exposed to UV light in the filter housing’s reaction chamber. This process also continues in the exhaust air duct. UV light breaks down the grease’s protein chains into smaller components. Ozone then converts the decomposed grease molecules into carbon dioxide, water and a small amount of dust. These residual products are then transported out with the exhaust air. Any excess ozone becomes oxygen. For the best possible decomposition of grease and odours, the exhaust air needs to be in contact with and react with the ozone for at least two seconds. The duct’s length should therefore be dimensioned so that it takes at least two seconds for the air to flow from the filter and out into the open air.

Greater reliability with air-cooled electronics

All electronics, such as ballasts that control the UV lights, are sensitive to high temperatures. At ambient temperatures of around 50 degrees Celsius, the useful life and reliability of electronics already start decreasing dramatically. This can result in not enough current being supplied to the UV lights, in which case the lights do not emit enough power or may even go out completely. In our design, the ballasts are air-cooled, which ensures full power of the UV lights even at temperatures around or above 90 degrees Celsius in the exhaust air. It is also important to protect the electronics from grease and ozone. We have therefore designed the air cooling process so that all ozone and air containing grease is effectively prevented from coming into contact with the ballasts, EMC filter, holders and cables.

Complete system

UV Safe is a complete filtration system consisting of the following components:

- Filter housing with UV tubes, measuring damper and wire mesh filter
- Filter cassettes (Cyklotec cyclone filter)
- Power unit
- Control panel
- All components are factory-assembled apart from the power unit and control panel

Control panel

UV Safe is controlled via the control panel. All necessary information can be found on the panel. At the bottom of the panel you can see how many hours are left until the UV tubes need to be replaced and when it is time for cleaning. A single keystroke takes you to the maintenance and service menu.

The control panel is activated by pressing the screen. The light-emitting diode (LED) in the bottom left corner glows green during operation.

 

Filtration in three steps

1.  In the cyclone filter, separation takes place with centrifugal force. Grease condenses against the wall of the cyclone and runs down into the collection vessel.

2. When the air passes through the wire mesh filter, the temperature drops and an even air flow is created. This is important in order to optimise the benefits of the UV light.
