The Right Choice
What About Ozone?
• UV radiation of the wavelength 185nm decomposes long-chain molecules by direct
photolysis and will generate ozone in the air when combined with oxygen
• Normally used for removal of grease and odor control in places like kitchen hoods and
industrial exhaust
How is ozone controlled in UV lamp applications?
• Regular glass fully stops UV-C emission
• Quartz glass allows UV to be emitted
• 3 types of quartz: natural, synthetic and doped
• Doped quartz completely stops ozone
• Natural quartz allows approximately 6% ozone emission
• Synthetic quartz allows approximately 10% ozone emission
• Most residential UV lamps are low pressure
• Typical low pressure UV lamps convert 40% of electrical power into UV-C emitted power
• FDA does not allow ozone levels in excess of 0.05 part per million by volume of air
circulating through the device or that cause an accumulation of ozone in excess of 0.05 part
per million by volume of air
• Alternative is TiO
