Earth‑Smart Emissions Control: Global Environmental Products Cummins DEF Head Unit
What is it?
The Global Environmental Products (GEP) Cummins DEF Head Unit is a mission-critical emissions control module integrated into the SCR system of environmental service vehicles powered by Cummins ISB, B6.7, or ISL engines. It delivers precisely metered Diesel Exhaust Fluid (DEF) into the exhaust stream to neutralize NOx emissions, while onboard sensors continuously monitor fluid level, temperature, and pressure—ensuring consistent dosing and reliable SCR system performance.
Why choose a GEP-specific DEF Head Unit?
Engineered to integrate seamlessly with Global Environmental Products chassis and Cummins engine systems, this DEF Head Unit offers plug‑and‑play compatibility with factory ECM calibration and wiring harnesses. It prevents SCR fault codes, engine derates, and emissions dosing inconsistencies that can arise with generic replacements. Built for rugged municipal and clean‑tech applications, it's designed to meet the unique demands of environmental service operation.
Key Benefits
✅ Direct-fit design for GEP vehicles using Cummins ISB, B6.7, or ISL engines
✅ Precisely regulates DEF dosing for optimal NOx reduction
✅ Integrated sensors monitor fluid level, temperature, and pressure in real time
✅ Designed to resist DEF crystallization, moisture, vibration, and thermal cycling
✅ Helps avoid SCR system faults, limp-mode events, and operational downtime
Applications
Ideal for GEP street sweepers, sewer vacuum trucks, stormwater clean‑up units, and other environmental fleet vehicles powered by Cummins engines. This unit ensures emissions compliance and SCR performance during frequent engine start/stop cycles and extended operation in variable conditions.
Installation Notes
Before installation, disconnect power to the vehicle and depressurize the DEF system. Clean the DEF tank and all fluid line connections thoroughly to remove residue or crystallization. Install the new head unit using OEM-style connectors and securely fasten all fluid and electrical lines. After installation, clear any diagnostic codes and verify DEF dosing and sensor readings using a scan tool.
Final Thoughts
If your Global Environmental Products vehicle shows DEF dosing errors, SCR derates, or emissions system warnings, the GEP Cummins DEF Head Unit offers the direct-fit, OEM-grade solution. Engineered for durability, emissions-precision, and seamless integration, it helps your fleet stay compliant and operational—available now at Tamerx to keep your clean-tech vehicles running clean and efficiently
