Ozone helps to reduce grease in the ducts an thereby significantly reduces the risk of fire.
Here we present comparative results from fires in two very similar restaurants in Finland. Both were à la Carte-style restaurants serving hamburgers, kebab, pizza etc. with conventional cooking appliances (not open fire).

On an average, Finland experiences from 20 – 30 grease fires annually that are so-called “close-to” situations. The worst exhaust duct fire in Finland occurred in 2010 in the city of Tampere. This was a historic building built in 1865 and the damage was so extensive that a complete restoration of the building was required. The restaurant was closed for more than 2 years and the total cost of the building renovation reached approximately 15 million Euros.
