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
- UL 2200 listed packages
- CSA Certified
- Certain restrictions may apply.
- Consult with your Cat® Dealer.
