NO and nitrogen dioxide NO is prescribed by law in Germany. Functional Principle The SCC-K NO / NO Converter converts the NO content of the sample gas by catalysis into NO (see also section “Conversion Principle”, page 19). To do this the sample gas is conducted through a special stainless steel cartridge with a catalyst-filling based on carbon-molybdenum.
NO into dinitrogen oxide O and elementary N . Depending on the ammonia concentration, this can cause a substantial reduction in the conversion rate. 42/23-52 EN Rev. 2 SCC-K NO / NO Converter Operator’s Manual...
Views from Front and Back Mounting The SCC-K NO / NO-Konverter is designed as compact, user-friendly and easy to service 19-inch plug-in unit for mounting in 19-inch cabinet systems. When fitted with a mounting bracket with a vertical swivel-holder, the converters can also be wall-mounted.
Ambient temperature during operation: +10 to +50 °C, during storage and transport: –25 to +65 °C ≤ 75 % annual mean, Relative air humidity occasional and slight condensation permitted SCC-K NO / NO Converter Operator’s Manual 42/23-52 EN Rev. 2...
