When your Dynapac equipment is powered by a Cummins ISB 6.7L engine, the DEF (Diesel Exhaust Fluid) circuit must operate flawlessly—or risk costly downtime and emissions faults. The Dynapac Cummins ISB 6.7L DEF Head Unit—built to OEM 3600821 standards—is a critical linchpin in monitoring and dosing DEF properly. A failing DEF head can lead to warning lights, engine derates, or system lockouts, which no operator wants mid-project.
-
Measures key DEF fluid parameters: level, temperature, and urea concentration, and transmits precise data to the engine control module
-
Controls accurate dosing of DEF into the exhaust stream, ensuring the SCR (Selective Catalytic Reduction) system can reduce NOx emissions effectively
-
Designed to OEM 3600821 specifications, guaranteeing a plug-and-play fit on Dynapac Cummins ISB 6.7L systems
-
Helps prevent emissions fault codes, warning indicators, and performance derates that stem from inaccurate sensor readings
-
Designed to endure the rigors of heavy equipment use—vibration, thermal cycling, and DEF’s corrosive nature
-
Easy to replace in the field, helping minimize machine downtime
In heavy equipment, even small sensor errors can cascade into big problems. Installing the OEM 3600821 Dynapac Cummins ISB 6.7L DEF Head Unit restores confidence in your emissions system, keeps your SCR functioning correctly, and helps protect you from surprise system failures. Don’t overlook this essential component—because your operation’s reliability may depend on it.
