Description

Dwyer SERIES CDTV CARBON DIOXIDE/VOLATILE ORGANIC COMPOUND TRANSMITTERS
Simultaneously Outputs Both CO2 / VOC

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.

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

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

Specifications:

  • Range: CO2: 0 to 2000 or 0 to 5000 ppm (depending on model); VOC: 0 to 2000 ppm CO2 equivalent
  • Accuracy: CO2: ±40 ppm ±3% of reading
  • Temperature Dependence: ±8 ppm / °C at 1100 ppm
  • Non-Linearity: CO2: 16 ppm
  • Pressure Dependence: CO2: 0.13% of reading per mm of Hg
  • Response Time: CO2: 2 minutes for 99% step change; VOC: 5 minutes
  • Temperature Limits: 32 to 122°F (0 to 50°C)
  • Duct Air Velocity Range: 0-4000 FPM (20.32 m/s)
