GR500-EP Industrial Ozone Generator. V4

Internal Reference: FABGR.0013

GR500-EP Industrial Ozone Generator. V4

Industrial Ozone Generator, cooled by water, to work from oxygen LOX or PSA. With PLC control with touch screen. Capacity to produce 500gO3/h of ozone, at a concentration of 148g/Nm3. 400V, 3P+N, 50Hz, 8.5kW. 

Robust, durable and highly efficient industrial ozone generator, designed and manufactured in Spain. This ozone generator needs an oxygen supply to produce ozone, either from a liquid oxygen tank (LOX) or from an oxygen concentrator (PSA). It achieves high concentrations of ozone with a really efficient electricity consumption rate. It also includes a powerful control unit: PLC, touch screen, data logging and remote access. Made with high quality components.

This ozone generator equipment includes a touch screen to easily program different treatments throughout the day using a recipe planner. When the equipment receives a running order it opens a motorized inlet valve allowing oxygen to enter. This flow of oxygen is conducted to the generation part, where the corona discharge is applied and the oxygen is transformed into ozone. With the oxygen flow meter you can regulate the desired flow.
