DAR-1400/ 2200 - Dilution Air Refinement System

Reduces levels of THC, CO and NOx in background air before it flows into the CVS. Ambient air is: Drawn into the system and heated to a controlled temperature Passed through a two-stage catalyst converter system Cooled through a heat exchanger Passed through a NOx oxidizing agent and activated charcoal Now, as purified air, piped to the remote mixing tee where it is mixed with the exhaust Application Purifies ambient air for SULEV-level emissions testing. Dehumidifier - Reactive Wheel Type Supplies dehumidified air to the DAR. Connected to the inlet of the DAR system, it includes a: 30% effective pre-filter Pre-cooling coil Desiccant dehumidifier Supply blower with 1 HP TEFC high efficiency motor HEPA final filter section Single point power connection for starters and disconnect, control voltage transformer Gravity pressure recirculation system to control discharge pressure at all flow rates below 200 Pa
