Process overview

How it works

When the generator receives a start command, the oxygen inlet solenoid valve opens and oxygen enters the unit through the regulated inlet. The oxygen from the cylinder or PSA is directed to the generation core, where corona discharge transforms part of the oxygen into ozone.

The oxygen flowmeter allows the desired flow rate to be adjusted, while the modular design makes it suitable for centralised systems using a single pneumatic line and one point of control.
