The Selective Catalytic Reduction (SCR) system is the heart of every BS-VI diesel engine. It helps convert harmful NOx gases into harmless nitrogen and water vapor. But the performance of this system depends heavily on the quality of Diesel Exhaust Fluid (DEF) you use. Using certified, high-purity DEF like NoxShield, manufactured by DDTech EcoVentures Pvt. Ltd., ensures smooth operation, longer SCR life, and lower maintenance costs
What Happens When You Use Poor-Quality DEF
Low-grade or contaminated DEF contains impurities like metals or urea residues that can clog the injector nozzles and crystalize inside the SCR catalyst. Over time, this causes:
- Sensor and injector blockages
- SCR system failure
- Expensive repairs and vehicle downtime
Why Certified DEF Matters
ISO 22241-certified DEF, such as NoxShield, guarantees precise urea concentration, ultra-low contamination levels, and consistent purity. This certification ensures:
- Optimal NOx reduction performance
- Reduced risk of system deposits
- Compliance with emission norms
- Extended DEF shelf life
Real-World Benefits for Fleet Owners
For fleet operators and industries running multiple diesel vehicles or DG sets, using premium DEF translates to measurable savings:
- Fewer engine faults and warning lights
- Longer catalyst and sensor lifespan
- Lower AdBlue/DEF consumption due to better efficiency
- Reduced downtime and maintenance overheads
