Built for Construction Durability: Dynapac Cummins ISB 6.7 L DEF Head Unit
What is it?
The Dynapac Cummins ISB 6.7 L DEF Head Unit is a high-precision emissions control module designed specifically for Dynapac heavy compaction and paving machines powered by Cummins ISB 6.7 L engines. It delivers accurately metered Diesel Exhaust Fluid (DEF) into the exhaust stream to neutralize nitrogen oxide (NOx) emissions while built-in sensors continuously track fluid level, temperature, and pressure—ensuring reliable SCR system operation even under demanding field conditions.
Why choose this Dynapac DEF Head Unit?
Purpose-built for Dynapac equipment calibrated to Cummins ISB power systems, this OEM-spec DEF Head Unit offers seamless plug-and-play installation with factory ECM wiring and calibration. It prevents DEF dosing irregularities, SCR error codes, and engine derates that may result from off-brand modules. Engineered for the harsh environments of job sites, it delivers emissions reliability when uptime and compliance matter most.
Key Benefits
✅ OEM-fit for Dynapac machines running Cummins ISB 6.7 L engines
✅ Precisely regulates DEF dosing for maximum NOx reduction
✅ Real-time monitoring via integrated sensors (fluid level, temperature, pressure)
✅ Built to withstand DEF crystallization, vibration, thermal shifts, and dust
✅ Minimizes SCR faults and ensures uninterrupted jobsite operation
Applications
Ideal for Dynapac rolling compactors, pavers, and asphalt equipment powered by Cummins ISB 6.7 L engines. This DEF Head Unit ensures consistent emissions control and compliance during strenuously continuous paving cycles and heavy-duty workload conditions.
Installation Notes
Before servicing, fully depressurize the DEF system and shut off power. Clean the DEF tank and lines thoroughly to remove any residue or crystal buildup. Mount the new module using OEM connector fittings and tighten all fluid and electrical connections securely. After installation, clear diagnostic codes and validate DEF dosing flow and sensor output using a diagnostic scan tool.
Final Thoughts
If your Dynapac machine shows DEF system alerts, SCR derates, or dosing inconsistencies, this DEF Head Unit offers the robust OEM solution you need. Designed for precision, durability, and jobsite resiliency, it restores emissions compliance and keeps your equipment moving efficiently. Available now at Tamerx.
