To utilize economical gas analysis methods in the monitoring technology required for this purpose, such as infrared measurement technology, the NO? content in the emission gas must be catalytically converted to NO. The conversion takes place in an electrically heated small reactor filled with a catalyst material specifically developed for this process.

The Bühler Nitrogen Oxides (NOX) Converter BüNOx 2+ series offers high energy efficiency, high conversion rate, and a long service life, with predictable maintenance enabled by an integrated maintenance computer.

Additionally, by inputting specific user data, the NOx calculator estimates the remaining service life of the conversion cartridge based on a stored standard curve and flags maintenance requirements upon user request.
