Ex-Situ Emission Monitoring Systems

State of art technologies

Cemstronalso offers a cost effective pre-engineered Ex-Situ CEMS to monitor stack gases for the optimum performance of the process and air pollution control devices. They are designed to perform the required daily zero and span checks automatically and unattended. Automatic calibration makes it less costly and time consuming to meet the environmental and process control requirements for daily validation of the system Typically Ex-Situ CEMS consist of Analyzer Panel with built in sampling system and full-extractive probe. The Analyzer panel is mounted nearby the sample probe where the sample gas is being drawn therefore it will eliminates the need of umbilical Our Ex-Situ system analyzer panels and probes are NEMA 4X rated for modarate ambient conditions and A/C units can be attached as per requested.

Examples of systems installed include:

  • Coal and Fuel Fired Boilers
  • Simple Cycle and Combined Cycle Combustion Turbines
  • Cement Kilns
  • Refineries

System Features:

  • All equipment is easily accessible via slide out instrument racks or panels. (Troubleshooting can be conducted on gas analyzers without disconnecting system tubing or signal wiring)
  • One year warranty on non-consumable system components
  • Rigorous functionality tests are completed at the factory with ALL system components (umbilicals, probes, cal gas regulators, etc) before shipping to customer site
  • Design features offer simplistic installation and system startups
  • System tubing and wiring clearly labeled to match system diagrams for easy troubleshooting
  • All system components used are industry proven for years of accurate, reliable trouble free operation
  • Multiple system sensors to alarm customer when malfunction occurs
  • Extra measurement parameters easily be installed (added gas monitors, etc)
