CDL carbon dioxide sensors maximize energy savings, while ensuring optimal ventilation. The sensors allow ventilation systems to be controlled by the amount of CO2 present in a space. The CDL 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 ensuring tenant comfort.
