    Schneider Electric’s Plant Room CO2 sensors maximize energy savings, while helping optimize ventilation. These sensors allow ventilation systems to be controlled by the amount of CO2 present in a space. The SCD Series detect fluctuations in CO2 levels and signal ventilation systems to provide an inlet of fresh air optimal for the space at a given time saving energy and increasing tenant comfort.


    • Controlling ventilation in response to occupancy
    • Office buildings, hospitals, industrial facilities, schools, retail stores, etc.
    • ASHRAE 62.1 air quality standard compliance
