This all-in-one solution represents a compact and cost efficient gas analyzing system for Continuous Emission Monitoring (CEMS).
It can be used for various operation units to monitor the emission limits required by authorities and to optimize process parameters.
CEMS-in-a-box includes a high precision NDIR analyzer, which operates in change-flow-mode (CFM) to ensure a stable zero point. Furthermore, this system includes an electric gas cooler, an autocalibration unit, a purge unit, a HMI and various I/O functions.
Measurement principle:
SO2, NOX, CO and CO2 are measured by a nondispersive infrared (NDIR) analyzer. As sample gas enters the analyzer, it gets filtered and precisely cooled down to 4°C, which minimizes humidity influences. Additional pressure regulation as well as temperature regulation allow measurements with highest accuracy. A Control Valve Unit enables a change-flow-mode technique to ensure a long-term stability.
Furthermore, an O2-sensor, a CLDmini, a purge unit, a housing cooler and an autocalibration unit can be integrated if necessary.
