JMI CRT Size A 9.5" DOC Module (Part No. 43956KDCR) is a PM3+ series component designed to provide effective diesel oxidation for heavy-duty emission control systems. This Diesel Oxidation Catalyst (DOC) is engineered to reduce carbon monoxide (CO), hydrocarbons (HC), and soluble organic fractions of diesel particulate matter, serving as the first stage in a verified CRT (Continuously Regenerating Technology) system. With its compact Size A 9.5" format, it's ideal for installations with limited space while still delivering reliable emissions reduction performance.
