Usage

CDW is a carbon dioxide transmitter to be used in
commercial environments.
Typical applications:
• office buildings
• conference rooms
• schools
• retail stores
CO based Demand Controlled Ventilation (DCV) allows
2
for ventilation based on occupancy while still maintaining
ASHRAE recommended per-person ventilation rates.
Over-ventilation of buildings can be reduced, energy can
be saved and air quality can be optimized.
