Built for Crane-Duty Precision: Tadano Crane Cummins ISL DEF Head Unit
What is it?
The Tadano Crane Cummins ISL DEF Head Unit is a core component of the SCR emissions system used in Tadano crane and lifting equipment powered by Cummins ISL diesel engines. It ensures precise injection of Diesel Exhaust Fluid (DEF) into the exhaust stream to neutralize nitrogen oxide (NOx) emissions, while its integrated sensors continuously monitor fluid level, pressure, and temperature to maintain reliable dosing and emissions performance.
Why choose a Tadano Crane-specific DEF Head Unit?
Engineered to seamlessly integrate with Tadano chassis and Cummins ISL engine control systems, this DEF Head Unit delivers a direct plug-and-play replacement without requiring modifications. With factory-grade calibration and OEM compatibility, it helps prevent SCR fault codes, limp-mode events, and emissions compliance failures—proven under the demands of heavy-duty crane applications.
Key Benefits
✅ Direct-fit for Tadano crane platforms powered by Cummins ISL engines
✅ Precisely regulates DEF injection to meet emissions standards
✅ Built-in sensors monitor DEF fluid level, temperature, and pressure continuously
