Stable Ozone Generator 2
Introduction
Stable Ozone Generators are designed as sources of stable ozone production in the range from 0.1 ppm to 5 ppm
(parts per million). These devices utilize the photochemical reaction of the 185nm emission line of mercury to produce
ozone from oxygen.
A unit consists of a stable source of 185nm radiation, a quartz reaction duct and radiation housing. The stable
radiation source consists of a Pen-Ray
®
mercury discharge lamp inserted into the radiation housing and an external
ballast power supply. This system, coupled with an appropriate supply of dry air or oxygen of uniform flow rate, will
provide a stable source of ozone for hundreds of hours of operation in instrumentation or other ozone-utilizing
systems.
Ozone Caution
The breathing of ozone in high concentrations is dangerous and should be avoided. Concentrations to 1.0 ppm are
considered to be the maximum allowable. Concentrations of 0.01 ppm can be detected by persons having a keen
sense of smell. For most people, ozone concentrations of 0.l ppm can produce irritation of the mucous membranes in
the nose and throat.
Warning: This lamp emits shortwave UV radiation. Exposure to excessive amounts of shortwave UV can cause
injury to the skin and eyes. Proper protective clothing and eyewear are recommended. For more information on
protective eyewear, refer to the accessories section of this manual or contact UVP.
Treatment
If excessive exposure to ozone should occur, the exposed person should be removed from ozone source and an
adequate supply of oxygen conveyed to the tissues. A medical doctor should be consulted as soon as possible.
