In this project, the chamber is filled with a high concentration of CO2. If the chamber falls below 92,000 PPM, the chamber must be refilled with CO2 gas. If the chamber rises above 95,000 PPM, this process will stop.
Registration is done by done a CO2 analyzer, which is located in the room. The CO2 analyzer is connected to a small PLC by means of a cable. This PLC controls a solenoid valve, which can allow a working pressure of 6 bar and a flow of 35 m3/h.
The display shows when the system is on, and when the valve is open or closed.
