The T200H/M uses a corona discharge (CD) tube for creating its O
generation is capable of producing high concentrations of ozone efficiently and with low
excess heat. Although there are many cell designs, the fundamental principle remains the
same (Figure 8-9).
Figure 8-9:
The T200H/M utilizes a dual-dielectric design. This method utilizes a glass tube with
hollow walls.
The outermost and innermost surfaces are coated with electrically
conductive material. The air flows through the glass tube, between the two conductive
coatings, in effect creating a capacitor with the air and glass acting as the dielectric. The
layers of glass also separate the conductive surfaces from the air stream to prevent
reaction with the O
. As the capacitor charges and discharges, electrons are created and

accelerated across the air gap and collide with the O
them into elemental oxygen. Some of these oxygen atoms recombine with O
The quantity of ozone produced is dependent on factors such as the voltage and frequency
of the alternating current applied to the CD cells. When enough high-energy electrons are
produced to ionize the O
commonly referred to as a corona, hence the name corona discharge generator.
