Industrial-Grade Emissions Reliability: SANY Cummins ISB 6.7 L DEF Head Unit
What is it?
The SANY Cummins ISB 6.7 L DEF Head Unit is a core component of the SCR (Selective Catalytic Reduction) system in SANY heavy equipment—such as excavators, cranes, and material handlers—powered by Cummins ISB 6.7 L diesel engines. It regulates Diesel Exhaust Fluid (DEF) injection into the exhaust stream to reduce NOx emissions, while integrated sensors monitor fluid level, pressure, and temperature for dependable performance under demanding conditions.
Why choose this OEM DEF Head Unit?
Designed exclusively for SANY chassis paired with Cummins ISB powertrains, this DEF Head Unit plugs into the factory ECM and wiring without adaptation. It reduces DEF metering inconsistencies, SCR fault codes, and engine derates that often occur with aftermarket components. Known for robust performance in jobsite environments, it helps maintain emissions compliance and equipment uptime.
Key Benefits
✅ Genuine OEM fit for SANY machinery using Cummins ISB 6.7 L engines
✅ Stable DEF delivery supports regulated NOx emissions reduction
✅ In-system sensors monitor fluid level, temperature, and pressure continuously
✅ Resilient to vibration, thermal shifts, moisture, and DEF crystallization
✅ Lowers likelihood of SCR errors, limp-mode activation, and costly downtime
Applications
Ideal for tough-duty SANY equipment—wheel loaders, excavators, cranes, and forklifts—powered by Cummins ISB 6.7 L engines. This DEF Head Unit supports SCR reliability through heavy-duty cycles, idle-heavy schedules, and prolonged operations.
Installation Notes
Ensure the machine is powered down and DEF system pressure is released before servicing. Clean the DEF tank and connector fittings thoroughly to remove contaminants or crystal buildup. Install using OEM connectors and secure all fluid and electrical connections properly. After installation, clear any diagnostic codes and verify DEF dosing and sensor data using a diagnostic scan tool.
Final Thoughts
When your SANY equipment powered by Cummins ISB 6.7 L engines shows DEF system faults, dosing issues, or ERR codes, this OEM DEF Head Unit delivers the dependable emissions performance you need. Tested for jobsite demands and emissions compliance—available now at Tamerx.
