In the event that the room needs to be shut down temporarily (as in the case of pre-cooler rooms, and
ripening rooms.), the control box disconnect switch is set to OFF. This disables all the purifiers
connected to the control box and keeps them from producing ROS. Setting the control box
disconnect switch to OFF will also disconnect the incoming electrical power to the control box,
allowing the front cover to be opened.
3. Programmable Logic Controller (PLC)
The PLC is programmed to control the operation of the purifiers that are connected to the control
box. It displays information about the operation of the purifiers and their environment(s).
Ozone Sensor
The sensor is mounted near the intake of the airflow in the room in order to measure the amount of ozone
(O
3
) present. The ozone (O
3
) is used as a marker to measure the level of ROS. The sensor is vital to control
the production level of the purifier according to the requirements of the application. This ensures an
effective and stable treatment.
