Drexel have developed Online Continuous Emission MonitoringSystem (OCEMS) which comprises of all the necessary parameterrequired to determine the concentration of gaseous emission andparticulate matter for BMWTP application. Also the systemincorporates cyclic control for Auto Clave into main frame Drexel hasinstalled more than 200 systems world wide..

For Biomedical waste treatment plants, this system includesfollowing parameters as specified in CPCB guidelines i.e.

  • CO ( Carbon Monoxide)
  • CO2 (Carbon Dioxide)
  • Zirconia O2 (Oxygen)
  • SO2 (Sulfur Dioxide)
  • NOX (Oxides of Nitrogen)
  • HCL (Hydrogen chloride)
  • HF ( Hydrogen Flouride)
  • Primary Incinerator Temperature
  • Secondary Incinerator Temperature
  • PM (Particulate Matters)


Drexel DX4B is a multi-parameter system, and it works on an extractive measurement technique wherein the emission levels are measured by extracting the heated gas from the stack, and before feeding to the analyzer it is cooled to the required sampling temperature. The Stack gas parameters are measured with NDIR and FTIR/DOAS analyzer assembly. SPM is measured with DC-Triboelectric and Laser Back Scattering Method.
