3. DEF Storage and Dispensing Solutions: Yara offers scalable DEF storage and dispensing solutions, including bulk tanks, IBCs, and pumps, enabling fleets to manage DEF supply efficiently while maintaining product quality and system compatibility.
4. AdBlue® Supply Contracts: Long-term AdBlue® supply agreements provide fleets with a secure, price-stabilized, and logistics-optimized source of DEF, ensuring consistent delivery and reducing operational risk across regional and national fleet operations.
5. Fleet DEF Usage Optimization: Yara provides fleet-specific DEF consumption consulting, helping operators reduce waste, prevent misuse, and match DEF consumption with driving patterns, improving environmental compliance and operational efficiency.
6. Mobile DEF Delivery Services: Mobile delivery services offer direct-to-depot or on-site DEF replenishment for fleet depots, reducing downtime, optimizing refill schedules, and ensuring regulatory compliance with minimal driver intervention.
7. AdBlue® Quality Assurance and Testing: Yara’s DEF quality testing services verify urea concentration, purity, and compliance with ISO 22241 standards to prevent SCR system damage and maintain emission control effectiveness.
8. SCR System Training for Fleet Technicians: Yara offers technical training for fleet maintenance personnel on SCR systems and DEF handling, ensuring proper maintenance procedures and avoiding common issues that impair emission system performance.
9. Emission Compliance Advisory Services: Compliance advisory services help fleet operators navigate regional and national emission regulations by optimizing DEF usage, selecting compliant vehicles, and preparing for 2025 low-NOx fleet requirements.
10. Sustainability Reporting Support: Yara provides sustainability data related to DEF usage, helping fleets track GHG emission reductions for ESG reporting, carbon accounting, and eligibility for 2025 clean fleet incentives and grants.
