ENDA-5000 series

Stack Gas Analysis System

Continuous simultaneous and high-precision measurement of NOx, SO2, CO, CO2 and O2

HORIBA has over 100,000 CEM systems installed and 30 years of quality and experience. That is the base on which HORIBA's new ENDA-5000 series of stack-gas analysis systems are built. These systems have a small footprint and use cross-flow modulated non-dispersive infrared (NDIR) and magneto-pneumatic detectors that are inherently drift-free. The ENDA-5000 series are superior continuous analysis systems that perform reliably for difficult exhaust gas measurements, when measurement errors cannot be tolerated. This CEM series features a new intuitive touch panel that makes every operation available with the touch of a single button. The ENDA-5000 series systems are also designed for ease of maintenance. They are ideal for a variety of uses, including emissions monitoring from steam boilers, refuse incinerators, and electric power generation plants to assure pollution standards are being met.

  • Long-term stability : Cross-flow modulated non-dispersive infrared (NDIR) detection is renowned for long-term stability
     
    1. No need for optical adjustments
      With  NDIR, the sample gas and reference gas are intromitted into a single measurement cell alternately to obtain modulation signal. Therefore there is no need to adjust two different optical paths so that they are balanced.
    2. A stable zero point
      Since ENDA-5000 series output the difference between the measured gas and the reference gas each time measurement occures (once a second), the zero point is extremely stable.
    3. Continuous cleaning keeps the cell clean
      Since cleaning air is fed into the sample cell in between each batch of sample gas, the cell resistes contamination and normally remains clean.This reduces span drift and makes the equipment safe and stable for long periods of time.
       
  • Compact : Body yields wider maintenance area
    ENDA-5000 series can be installed almost anywhere, with ample room on all sides for easy access and much easirer maintenance.
     
  • Easy to use : Features an intuitive touch panel
    The operator can easily switch between the corrected and converted density settings screens or view alert information with touch of a single button.
     
  • Complies to world enviroemental regulations by local engineering

<Other Features>

  • Continuous simultaneous measurement of up to 5 components with one system
    HORIBA's innovative optical technology enables ENDA-5000 series measure up to five components which can be arranged any combination.
     
  • Correction for interference
    The interference correcting sensor uses a unique interference filter to compensate for the influence of interference by other gases.
     
  • Better alerts and extra alerts
    In addition to the alert functions available in the past, the ENDA-5000 series feature extra alert functions. A continuous checking process can prevent the unit from stopping due to a failure, reducing the risk of failed measurements and assuring consistent operation.
     
  • Dramatically reduced correction time for SO2
    Corrections of SO2 measurements using wet base methods of the past took a great deal of time (about 15 minutes), but with the ENDA-5000 series' dry base method, correction takes only three minutes.
