Product Details

THE SERIES CDTV CARBON DIOXIDE / VOLATILE ORGANIC COMPOUND (VOC) TRANSMITTER reduces energy cost in buildings by lowering the amount of conditioned air based on the occupancy of the space. By sensing both CO2 and VOC, the transmitter can detect fumes that may need to be exhausted during lower occupancy periods.

Approvals:
• CE Approval

Features:
• Combination VOC and CO2 outputs reduce labor and material costs
• Single beam dual wavelength NDIR CO2 sensor allows for use in spaces that may be occupied 24 hours a day
• VOC output is correlated to be equivalent to CO2 measurements
• Ventilate using ASHRE’s occupancy-based VRP Algorithm

Applications:
• HVAC applications in hospitals, schools, and commercial buildings
• Demand control ventilation
• Odor control
• Waiting rooms or other spaces that may be occupied 24 hours a day
