What is it?
The SANY Cummins ISB 6.7L DEF Head Unit is a precision emissions module integrated into the Selective Catalytic Reduction (SCR) system of SANY heavy machinery powered by Cummins ISB 6.7L engines. This unit correctly meters Diesel Exhaust Fluid (DEF) into the exhaust stream to neutralize nitrogen oxides (NOx). Its onboard sensors monitor DEF fluid level, temperature, and pressure to ensure accurate dosing and dependable SCR functionality.
Why choose a SANY-specific DEF Head Unit?
Engineered for seamless compatibility with SANY chassis and Cummins ISB 6.7L engine control systems, this unit offers factory-aligned calibration and plug‑and‑play installation. It helps prevent SCR fault codes, engine derates, and dosing inconsistencies that often result from using generic replacements. Built to endure rugged construction environments, this OEM-grade head unit delivers emissions control reliability you can trust.
