Multiquip 8983029372 SCR Assembly - OEM Replacement Part for Super Silent Generators

The SCR Assembly is a critical emissions control component that manages selective catalytic reduction in diesel-powered generators, ensuring compliance with emission standards while maintaining optimal engine performance. This assembly monitors and controls the SCR system that reduces nitrogen oxide (NOx) emissions through the injection of diesel exhaust fluid (DEF).

In the DCA70SSIU4F WhisperWatt generator equipped with the Isuzu BR-4JJ1X diesel engine, the SCR system features a three-stage fault protection system. Warning Level 1 and Level 2 malfunctions trigger staged alerts through the control panel, while Level 3 malfunctions result in emergency shutdown with slow blinking indicators. When emergency shutdown occurs due to SCR system errors, the unit may enter ESCAPE MODE and require up to 30 minutes before restart capability is restored. Regular monitoring of the SCR system is essential to prevent unexpected downtime and maintain the generator's 56 kW prime output (70 kVA) and 62 kW standby output (77 kVA) capabilities at 1,800 rpm operation.
