  • Interfaces with any type of system control
  • Very low NOx: < 50 mg/kWh (based on 3% O )

O2 sensor

The O2 sensor ensures that the combustion quality remains constant; perfect flame characteristics are maintained (O2 level) whatever the boiler output.

Air excess is permanently and automatically corrected by the O2 sensor, which will modulate the rotation speed of the air fan to meet any variation in combustion needs.

All the variations in combustion parameters such as flame quality, atmospheric pressure or air temperature, gas temperature and pressure, chimney negative pressure are automatically corrected by the built-in modulation controller (IMC) and the O2 sensor.
