Dilution Air Refinement System

  1. Reduces levels of THC, CO and NOx in background air before it flows into the CVS. Ambient air is:
  2. Drawn into the system and heated to a controlled temperature
  3. Passed through a two-stage catalyst converter system
  4. Cooled through a heat exchanger
  5. Passed through a NOx oxidizing agent and activated charcoal
  6. Now, as purified air, piped to the remote mixing tee where it is mixed with the exhaust

Features of Dilution Air Refinement System

  1. Facilitates measurement of level exhaust gas with greater accuracy.
  2. HC < 0.1 ppm.
  3. CO < 0.1 ppm
  4. NOx < 0.1 ppm
  5. Maximum flow rate may be switched to three preset lower flow rates.
