Grease deposits in kitchen hoods and exhaust air ducts of commercial kitchens cause high maintenance costs, severe odor nuisances and increased fire hazards. Treatment with high-energy UV radiation photolyzes, destroys and neutralizes the molecules of grease and odors. This keeps the kitchen hood surfaces clean and substantially minimizes exhaust ductwork cleaning and maintenance costs.
See how UV light can reduce odor and grease in foodservice kitchens!Here are some application examples:
- Less kitchen smells and fire harzard thanks to special UV lamps
- UV technology solves challenges with kitchen odors, annoyed neighbors and the environmental agency
- Chinese Restaurants: a lot of grease production equals a lot of filter replacements
Kitchen hood exhaust air cleaning with UV in Heraeus cafeteria:
Especially in large-scale foodservice establishments, the use of fats and oils causes unpleasant smells and stubborn deposits in exhaust air ducts and kitchen rhoods. Fat separators in the kitchen exhaust hood can remove only up to 95% of the grease carried along in the exhaust air flow.
The rest is deposited in the hood and the exhaust air duct. This makes cleaning difficult, but above all it creates a high fire hazard.
Heraeus Noblelight ‘sspecialized vacuum UV lamps for kitchen exhaust hoods,
in the wavelength of 185 nm (VUV), photolyze, neutralize, and destroy the grease molecules and odors.
Before the installation of the Heraeus Noblelight kitchen module the kitchen hood is contaminated with grease. This causes high maintenance costs to clean as well as odor problems.
After 3,000 hours of operation with the Heraeus UV solution the kitchen hood and exhaust air duct grease accumulation is significantly less.
The management of the language school Humboldt Institute.V. was under pressure from the city environmental agency after neighbors of the language school complained about odors. If the odor problem couldn’t be resolved, the school faced the prospect of having to shut down the kitchen, leaving the students without meals. Upon visiting the kitchen facilities (a kitchen hood of around 4,000 cubic meters/hr, running 2 shifts of warm food and 1 shift of cold food), it was clear that UV could be a good solution.
Large kitchens in shopping malls or office buildings require an especially good exhaust duct and filter system to keep the environment clean and minimize odors. In Chinese restaurants though, the grease accumulation is high and the filters protecting the ventilation system in a building in Birmingham, UK had to be changed every week. These filters were not only expensive, but also required a lot of maintenance time to replace.
To save costs, time and disposal, Jacobs Bond Pascoe Ltd. installed a UV solution from Heraeus.
