5 Decomposition of grease accumulation
During the photolysis process (also known as photodissociation), ultraviolet radiation reacts with air drawn in through the exhaust pipe of a kitchen range hood. In this process, photons break down oxygen molecules into oxygen atoms. The oxygen atoms combine with any remaining oxygen molecules to form ozone molecules, and the ozone molecules react with organic compounds in the grease.
This chemical reaction, called ozonolysis, will change the oily organic compounds in the exhaust gas, forming byproducts that are easier to clean, especially carbon dioxide and water vapor. Facts have proved that ozone decomposition can significantly reduce the accumulation of grease deposits in grease discharge pipes and engine hood discharge systems.
The advantages of ultraviolet lamps in the exhaust system of kitchen range hoods
Reducing grease accumulation reduces the maintenance and cleaning required for the kitchen range hood exhaust, and also reduces the possibility of grease fires in the kitchen exhaust system. As we all know, ozone can eliminate bad odors in the air, so ozone decomposition helps to eliminate the odor caused by the accumulation of grease, which can happen quickly in busy commercial kitchens.
The UV germicidal lamp in the UV kitchen exhaust system helps restaurant owners obtain many benefits, including:
- Significantly reduce the accumulation of grease in the kitchen exhaust
- Eliminate erroneous instructions from old, accumulated grease
- Reduce the risk of fire in the kitchen exhaust system
- Save cleaning and maintenance costs
- Support sustainable heat recovery
- Although UVC technology is safe and chemical-free, direct exposure to skin and eyes should be avoided. The safety measures of turning off the ultraviolet light when the kitchen exhaust device is turned off can protect the kitchen personnel.
It is important to use reputable UVC germicidal lamps and range hood exhaust systems to ensure the proper decomposition of molecules and the safety of kitchen and restaurant staff. The UVC system should be installed in the exhaust pipe of a kitchen range hood with multiple interlocks to ensure that the UV lamp is turned off when the exhaust system is closed or the filter is removed to prevent human exposure.
