Mini-cabinet DeNOx

Heated Turnkey Gas Analysis System ideally suited for fast, continuous and simultaneous measurements of NH3 and NOx in DeNOx applications (SCR and SNCR).

In DeNOx systems using urea injection with ammonia (NH3) as a reducing agent, the flow rate and control of NH3 must be continuously adjusted and controlled to prevent excess NH3 emissions (slip), to reduce environmental impact and cost of reagents. To optimize this process, it is essential to use an emissions analysis system for simultaneous and continuous monitoring of NOx and NH3.



  • Pre and / or post catalyst measurement of NOx and NH3 for all types of engines using DeNOx
  • Emissions monitoring for Incineration, Cogeneration, and other processes using catalytic DeNOx systems



  • Sampling system with self-regulated heated line (191°C) and 2 microns heated filter integrated
  • Additional heated filter in standby, for instant replacement through ‘'Quick Lock'' connection system (optional)
  • Calibration and zero gases can be injected to the heated probe for system integrity check, leak test, system calibration
  • Automatic and programmable backflushing (air or N2) for filter cleaning

Analysis cabinet:

  • Fast and easy to move between test cells (cabinet mounted on castor wheels)
  • Secondary safety filter (1.5 microns) embedded in the cabinet
  • Ultra low maintenance, no moving parts
  • Modular design for addition of other analyzers (THC, CO, CO2, O2)
  • No interference or quenching effect with CO, CO2, H2O and other gases
  • Analyzers with fast response time (<2 sec)
  • Communication by AK protocol (RS232 / RJ45)
  • Specially designed software (Windows PC)
  • Dual measurement possible (pre and post catalyst)







  • Measurement of THC, NO, NO2, NOx, CO, CO2, O2 and NH3
  • Hang-up checker - used to check for hydrocarbon hang-up in the sample lines
  • Heated sample line; 10 meters + 3 meters
  • Heated sample line selector
  • Heated sample pump
  • Back-flushing filter function
  • Heated stainless steel filter
  • Remote display & control
