Applications

  • The CO2 sensing system uses real time CO2 measure-ments to determine actual occupancy during the day. A system using the CO2 sensor adjusts outside air delivery to provide only the amount of ventilation needed, thus virtually eliminating 100% of excessive amount of outside air used in a building
  • For the CO2 measurement, a "Non Dispersive InfraRed (NDIR)" technology with automatic self-calibration is used

Special Features

  • Easy installation
  • Maintenance-free
  • Compact and robust design
  • Standard offering includes mounting flange
