Features

The in situ zirconia oxygenanalyser , designed for ATEX zones (refineries, petrochemical plants, boilers), enables precise combustion control.

Measuring the oxygen concentration in the effluent enables the air/fuel ratio characterizing combustion to be monitored.

This is essential for controlling efficiency and ensuring process safety. This analysis system is designed for demanding applications in potentially explosive atmospheres:

  • Refining furnaces
  • Petrochemical furnaces
  • Large industrial boilers

 

The ZFKX detector is ATEX and IECEx certified and can be used in environments classified as Zone 1 IIB+H2 T3 Gb.
