UV Light in Kitchen Exhaust Systems

UV Hood Technology

Every minute of every day, it seems there is a technological advancement that changes the way we do business. The most recent and interesting technological advancement in the kitchen exhaust system industry is the use of UV light.

How Does a UV Hood Work?

The basic design of a UV hood includes long cylindrical UV light bulbs that are mounted into cabinets behind the baffle filters in the hood work. These UV lights help to break down grease molecules in the exhaust air stream. When the molecules split they create two new substances, ozone, and dry carbon ash. The result is that instead of having a duct system full of liquid grease fuel, you end up with a duct full of low combustion ash.

Does the Exhaust System Still Need to be Cleaned?

The answer is yes it does, but much less often than a non-UV system.

How Often Does the UV System Need to be Maintained?

Daily in most kitchens. UV exhaust systems utilize multi-stage filters to catch larger grease particles which the UV light cannot break down. Those filters clog up very quickly in heavy load systems. If the filters are not taken down and cleaned nightly, the large grease particles can pass into the hood and UV light cabinet causing the bulbs to coat with grease and fail.

New Technology Still Requires Proper Maintenance

Like with any new technology, new advantages also come with new requirements for the technology to function properly. If your company is considering utilizing this technology, reach out to an IKECA certified vendor with experience cleaning UV systems. The manufacturers are not always as clear about the maintenance requirements as they could be. The exhaust company can help you put together a maintenance plan to ensure your new UV hood system functions properly and without issue.
