Safety Precautions
Ozone is a powerful oxidizing agent. Observe
strict operating procedures while using ozone
equipment. It is imperative that only ozone com-
patible materials are used in conjunction with
the ozone system.
Ensure that the Ozone Generator is in a well-
ventilated area. Do not allow rain or condensation
to contact the Ozone Generator. The Ozone Gener-
ator is not weather proof. The unit must be opera-
tor indoors or in an enclosure which is placed in a
non-condensing environment.
Carefully review and familiarize yourself with the
following important safety information concerning
the Ozone Generator:
1. Ozone is an extremely aggressive and power-
ful oxidizer. The Occupational Safety and
Health Administration (OSHA) 8-hour expo-
sure limit is 0.10-PPM. The OSHA 15-minute
exposure limit for ozone is 0.3 PPM. Above
0.3 PPM, there is the risk of damage to respira-
tory tissues.
2. People who have no sense of smell should not
operate this equipment.
3. Never attempt to verify ozone production by
directly breathing or smelling the ozone outlet
or the ozone-tubing outlet.
4. The Ozone Generator contains high voltages.
Unauthorized entry can result in serious injury
or death. For service instructions, contact
Ozone Solutions.
5. Make sure all tubing connections between the
Ozone Generator and the injection point are
secure and in good working condition. Failure
to do so could result in the discharge of ozone
into an undesired space.
Introduction
The Water Cooled Ozone Generator produces
ozone from oxygen via corona discharge. The TG
series is capable of generating 75- 600g/hr of
ozone with a feed gas of 90% oxygen Ozone has
many uses including pathogen inactivation and
destruction of odorous gases.
Ozone Generation from Corona Discharge
Theory of Operation
The Ozone Generator produces ozone via the co-
rona discharge method. This process uses an elec-
trical spark to split the molecular bond of natural
diatomic oxygen to form the atomic O- form of
oxygen. These O - atoms then bond to other O2
molecules to form O3 (ozone).
The spark inside the corona cell is a controlled
corona or spark. This spark is produced by forcing
a high voltage source through a dielectric and a
small air gap where the feed-gas flows through.
The spark occurs at a higher-than-line voltage and
much higher-than-line frequencies, which are in-
creased and regulated by the onboard electronics
in the machine.
The basic fundamentals of flow and velocity of
gas through the corona cell allow for more ozone
production (g/hr.) as oxygen flow increases. As
the flow increases, the concentration of ozone (%
by weight) decreases. Conversely, as the flow de-
creases, the concentration of ozone increases. At
very low oxygen flow rates, the oxygen remains in
the corona cell for a longer period of time.
Note: If the operator has asthma, he or she
must not enter an airspace that has a signifi-
cant ozone concentration. Ozone can in-
duce an asthma attack.
