Cat Clean Emissions Module (CEM)

  • The Tier 4 Final engine has been optimized to work with the Cat CEM.
  • The CEM is a reliable, compact, and lightweight system that gives maximum installation flexibility.
  • It features a diesel oxidation catalyst for particulate matter (PM) and hydrocarbon (HC) control.
  • Selective catalytic reduction (SCR) reduces NOx output and provides integrated sound attenuation.
  • The CEM is controlled by a separate dosing module that has been integrated into the standard generator set controls for complete monitoring, protection and closed loop NOx control.
  • For more information on the CEM, refer to cut sheet LEHE0359.

UL 2200 / CSA - Optional
