Legionellosis often represents a not considered risk in biological risk evaluation of schools, but epidemics have been discovered in environments like schools, hotels and hospitals

Alisea Fire aims to prevent and eliminate the risk of fire and systems malfunctioning due to the presence of greasy, charred or viscous deposits in the extractor hoods or intake ducts for unburnt fumes used in canteen, hotel, restaurant and community kitchens.

The consequences of poor maintenance of extractor systems for unburnt fumes remarkably increase the risk of fire, causing malfunctioning and determining a problematic state of hygiene. The diagrams show the real effects of the work carried out by Alisea’s technical staff and make it easier to understand the optimal results that could be obtained than too many words by our professionalism.
