How it Operates

GRZO range ozone generators feature a touch screen for simple programming of various treatments throughout the day. Upon receiving a command, the refrigeration circuit activates and the compressor begins drawing air from the atmosphere. This air is then filtered, dried, and passed into the PSA where nitrogen is removed. The oxygen is concentrated to a purity of 95% and directed to the generation system, where corona discharge transforms it into ozone. Additionally, an oxygen flow meter allows for the adjustment of the desired flow rate.
