UL2 Urea dosing system-supply unit & dosing unit-part two
Bosch Denoxtronic 2.2 SCR System
Innovative Technology To Enhance Performance.
The proprietary design of the UL2 system offers many features that optimize dosing spray performance. This reduces deposit formations and enhances mixing capabilities to significantly improve reliability. The benefits of our technology include:
—A pressure-swirl atomizer, which offers customized spray angles and flow rates
—Reduction of droplet size to as low as 24 microns SMD, promoting improved NOx conversion efficiency
—A diverter valve for high-horsepower usage, which diverts pressure to allow more urea to be released, for high-flow optimization
Designed For Freeze-Robustness.
The UL2 is the only liquid-only dosing system in the market offering freeze-robustness in its design, and improved reliability, as urea is continuously present within the unit to prevent doser crystallization and clogging. The benefits of this technology include:
—Eliminating the need for power after key-off, providing freeze-robustness
— Quicker dosing readiness at key-on; avoids priming issues with pump, as no purging is necessary
— Quicker NOx treatment and prevention of crystallization, as urea is always present in system
— Prevents system damage during intentional or unintentional interruption of power to the vehicle
Eliminating Urea Challenges.
The UL2 system has been designed to withstand and overcome many urea challenges that other competitive systems cannot tolerate during the dosing process. Our superior system has successfully undergone urea compatibility testing to:
— Use potted electrical components to prevent infiltration
— Utilize static-only sealing to avoid urea leakages and short circuits
— Prevent crystallization by continuously keeping urea present within the unit
