Dynapac Cummins ISB 6.7L

Dynapac’s Solution for Reliable DEF Delivery – Cummins ISB 6.7L

What is it?
The Dynapac Cummins ISB 6.7L DEF Head Unit is a critical module in the Selective Catalytic Reduction (SCR) emissions system used by Dynapac heavy compaction and paving equipment equipped with Cummins ISB 6.7L engines. It meters Diesel Exhaust Fluid (DEF) into the exhaust stream to neutralize nitrogen oxides (NOx), while integrated sensors continuously monitor fluid level, temperature, and pressure for accurate emissions dosing and system reliability.

Why choose the Dynapac-specific DEF Head Unit?
Tailored to integrate seamlessly with Dynapac chassis and Cummins ISB engine systems, this DEF Head Unit offers factory-aligned calibration, wiring harness compatibility, and plug-and-play installation. It helps prevent SCR fault codes, engine derates, and dosing inconsistencies often introduced by generic replacements, and is engineered specifically for job-site durability and equipment lifecycles.

Key Benefits
✅ Direct-fit compatibility with Dynapac equipment powered by Cummins ISB 6.7L engines
✅ Precisely regulates DEF injection for consistent NOx reduction
✅ Built-in sensors monitor DEF level, temperature, and pressure in real time
✅ Resistant to crystallization, vibration, thermal cycling, and dust exposure
