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.
