Using solenoid valves and sensors, gas mixtures are injected in the quantities necessary to reach the required concentrations in each chamber using oxygen from the air and packaged CO2 and N2. Each chamber has solenoid valves at its gas inlet and outlet, as well as a mixing fan, to accelerate homogenization inside each chamber.
The automatic control is carried out through an industrial computer that, based on the information from the sensors, activates the entry and exit of gases necessary to each chamber, to maintain the desired concentrations (previously configured), to guarantee maximum reliability of the system.
