Description
The use of UVC ozone (O₃) chambers in industrial kitchen hood exhaust systems is a widely preferred method, especially for air purification and odor elimination.
Ozone is a powerful oxidizing gas composed of three oxygen atoms, and it is commonly used in industrial applications due to its ability to neutralize unpleasant odors.
Here is more detailed information about these filtration units:
How Does the UVC Ozone Chamber Work?
Stage One:
High-intensity UV radiation oxidizes grease and oil vapors, breaking them down into vapor and more manageable byproducts.
Stage Two:
The UV lamp generates ozone (O₃). As a highly potent oxidizing agent, ozone breaks down organic compounds.
It also acts as an effective deodorizer and air sterilizer.
This two-stage system provides an ideal solution for grease breakdown, odor elimination, and air purification in commercial kitchens.
Ozone Generation Explained
Ozone is produced by UV lamps that do not contain titanium dioxide (TiO₂) coating, which normally blocks wavelengths below 200 nm.
At a wavelength of 185 nm, UV light splits oxygen molecules (O₂) into unstable oxygen atoms (O). These atoms then combine with other O₂ molecules to form ozone (O₃).
Ozone is a powerful oxidizer and an extremely effective disinfectant. It breaks down organic molecules in the air, including grease and oil particles in kitchen exhaust systems. However, ozone is short-lived—it reverts to regular oxygen (O₂) within 20–30 minutes at room temperature.
A Scientific Breakthrough in Odor and Grease Control
UV ozone technology is considered one of the most effective solutions for eliminating unwanted odors, oil vapors, and grease particles.
However, for heavy smoke cooking applications (e.g., charcoal grilling), it is recommended to use additional filtration, such as industrial air cleaners or electrostatic filters, for optimal results.
Installation Recommendations
-
DOZ units should be installed as close to the kitchen hood as possible (and as far as possible from the exhaust outlet) to maximize contact time with contaminated air.
-
For best performance, air retention time in the duct should be at least 0.1 to 0.2 seconds or longer.
Key Advantages
-
Prevents odor complaints, especially in restaurants with strong-smelling cuisines.
-
Helps reduce grease buildup in ductwork and exhaust systems.
-
Eases the burden on other filtration systems.
-
Requires no chemical agents.
-
Long service life when properly maintained.
-
Extends the lifespan of activated carbon filters when used together.
Why Is It Important?
-
The ozone produced is introduced into the kitchen air through the hood’s suction system, purifying the contaminated air.
-
It breaks down grease particles, burnt food odors, and other cooking-related smells.
-
Ozone oxidizes and neutralizes odor molecules effectively.
