CARBON DIOXIDE/VOLATILE ORGANIC COMPOUND TRANSMITTERS

Simultaneously Outputs Both CO2 / VOC

AIR QUALITY

North American style

The Series CDTV Carbon Dioxide/Volatile Organic Compound Transmitters reduce energy cost in buildings by lowering the amount of conditioned air based on the occupancy of the space. By sensing both CO fumes that may need to be exhausted during lower occupancy periods.

FEATURES/BENEFITS

• Combination VOC and CO

2 outputs reduce labor and material costs

• Single beam dual wavelength NDIR CO be occupied 24 hours a day

• VOC output is correlated to be equivalent to CO

• Ventilate using ASHRAE’s occupancy-based VRP Algorithm

APPLICATIONS

• HVAC applications in hospitals, schools, and commercial buildings

• Demand control ventilation

• Odor control

Transmitters

• Waiting rooms or other spaces that may be occupied 24 hours a day
