UV Safe

UV Safe is a complete system for grease and odour reduction in professional kitchens. The exhaust air is filtered in three stages.
1. First, most of the grease particles are separated in the Cyklotec cyclone filter.
2. Additional filtration and temperature reduction then takes place in a wire mesh filter.
3. 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.

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.

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 efficient 3-stage filtration process minimises the need to clean the exhaust air duct. Since no flammable grease reaches and sticks to the inside of the exhaust duct, the risk of fire spreading via the duct system is also minimised.

Odours are almost always produced when food is prepared. These substances are often in gas form and cannot be captured by conventional filters. The odours therefore escape into the open air together with the exhaust air from the kitchen.

With UV Safe, these odours can be reduced to a minimum. The ozone oxidises with the odour-producing molecules, leaving only water, oxygen and carbon dioxide.
Eliminating unpleasant odours with ozone is a well-tested and proven method. This technique is common in areas such as the fish, food and process industries

Oily and fat air from professional kitchens is not very suitable for heat recovery, despite the large energy content. The warm exhaust air filtered with UV SAFE is free of grease and is therefore ideal for heat exchange. If heat-exchanging batteries with separate supply and exhaust air connection are used, odor transfer is avoided.

When installing rotary heat exchangers, the plant is supplemented with activated carbon filters from Acticon to avoid odours.

When cleaning, open the filter housing cover so that the filter and the cyclone filter can be taken out for cleaning in a dishwasher. When the cover is opened, the UV light tubes are also easily accessible for wiping, which should always be done in conjunction with the filter cleaning.
This design ensures that all important components requiring regular cleaning are fully visible and easily accessible. Nothing can be ”forgotten”. The system also uses an audio signal to remind you when it’s time for cleaning.
UV Safe is a user-friendly system, with a design that ensures efficient and safe operation.

Our activated carbon filters absorb gaseous contaminants. In order to achieve optimal filtration, it is important that the contaminated air is in contact with the activated carbon for as long as possible. A contact time of 0.25 seconds is sufficient in most cases. Over time, the activated carbon becomes saturated and the filtration capacity declines. The useful life of the filter is dependent on the amount of activated carbon and contaminants. The normal useful life varies from six months to two years.
