Dwyer SERIES CDTV CO2/VOC Transmitter

Dwyer 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.

Applications: HVAC applications in hospitals, schools, and commercial buildingsDemand control ventilationOdor controlWaiting rooms or other spaces that may be occupied 24 hours a day

Dwyer Series CDTV Carbon Dioxide/Volatile Organic Compound Transmitter simultaneously outputs Both CO2 / VOC.

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
