EcoFit UL2 Liquid-Only Urea Dosing System

The proprietary design of the spray nozzle on the Cummins Emission Solutions EcoFit UL2 Liquid-Only Urea Dosing System offers improved atomization of urea.

• Freeze-robust components allow for optimal pump-priming and the prevention of crystallization throughout the unit
• Offers proven reliability throughout the year in varying climates
• Allows customization in flow rates and spray cone angles
• Intelligent doser, with temperature and pressure sensors at point of injection, allows for flexible vehicle integration by accommodating varying dosing line lengths without affecting controls
• Dosing nozzle provides improved oxides of nitrogen (NOx) conversion efficiency rates
• Droplet sizes are comparable to those of air-assisted systems and the likelihood of urea droplets in the Decomposition Reactor is significantly reduced
• Freeze robustness enables urea to remain in the system at all times, even during freeze events
• Keeping urea in the system prevents clogging, eliminates need for power at key-off for purging, allows quicker dosing at key-on and prevents damage to system during power interruption of vehicle
