When the ozone generator receives a start order, it opens the inlet valve allowing oxygen to enter the equipment. The manual inlet reducer maintains the range of desired oxygen pressures. Once the pressure is regulated, the oxygen is conducted to the ozone generation shell, where the oxygen is exposed to a strong electric field that dissociates the molecule into oxygen, into free atoms. These atoms are recombined 3 by 3 creating the ozone molecule O3, a very reactive and oxidizing gas. The gas flowmeter continuously measures the ozone flow rate, and through the proportional valve it is adjusted to the desired flow rate. The power in kw of the equipment can be varied manually on the screen, or by means of an external 4-20mA signal.  

If it does not detect water flow, oxygen flow, or the cooling temperature is not adequate, the generator will give an alarm and stop for safety
