Mix-Ready Emissions Control: Hollingshead ISB 6.7L DEF Unit
What is it?
The Hollingshead Mixer Cummins ISB 6.7 L DEF Head Unit is a precision emissions module designed for industrial mixer platforms powered by Cummins ISB 6.7 L engines. It meters Diesel Exhaust Fluid (DEF) into the exhaust stream to neutralize nitrogen oxide (NOx) pollutants while integrated sensors continuously monitor fluid level, temperature, and pressure to maintain smooth SCR system operation even under the harshest mixing conditions.
Why choose the Hollingshead-specific DEF Head Unit?
Custom-engineered for seamless integration with Hollingshead chassis and Cummins engine calibration, this OEM-grade module offers plug‑and‑play compatibility with factory ECM logic. It prevents dosing inconsistencies, SCR fault codes, and engine derates typically encountered with aftermarket parts. Built to endure continuous mixing operations, vibration, and temperature extremes, it ensures consistent emissions control on the job.
Key Benefits
✅ Direct-fit solution for Hollingshead mixers using Cummins ISB 6.7 L engines
✅ Precisely regulates DEF dosing to maximize NOx reduction
✅ Real-time fluid level, temperature, and pressure monitoring via internal sensors
✅ Engineered to resist vibration, thermal cycling, dust, and DEF crystallization
✅ Helps prevent SCR errors, engine derates, and operational downtime
Applications
Ideal for Hollingshead industrial mixer platforms, such as tank agitators, bulk material movers, and specialty mixing vehicles powered by Cummins ISB 6.7 L engines. This DEF Head Unit ensures emissions compliance and smooth SCR operation across demanding, continuous-duty cycles.
Installation Notes
Before servicing, power down the unit and relieve pressure in the DEF system. Thoroughly clean the DEF tank and fluid lines to remove residue or crystal buildup. Install the unit using OEM-style connectors and secure all fluid and electrical connections. After installation, clear diagnostic codes and test DEF dosing and sensor performance using a diagnostic tool.
