The medium frequency water-cooled ozone generator uses air (or oxygen) as raw material and uses medium frequency high-voltage AC power for corona discharge to generate ozone. It is the latest generation of ozone generator developed to achieve GMP certification for HVAC systems in the pharmaceutical industry and has obtained national patents. This equipment mainly consists of four parts: gas source treatment system, power control system, ozone generation system, and automatic protection system. The automatic protection system includes liquid level, phase loss overload, temperature and pressure protection control, and the ozone production is adjustable. An online monitoring and printing system can also be configured according to customer needs to achieve real-time online monitoring of ozone data.
