The Dwyer 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 for the CDTV include:

  • 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
