Innovative Technology To Enhance Performance

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:
n A pressure-swirl atomizer, which offers customized
spray angles and flow rates
n Reduction of droplet size to as low as 24 microns
SMD, promoting improved NOx conversion
efficiency
n 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:
n Eliminating the need for power after key-off,
providing freeze-robustness
n Quicker dosing readiness at key-on; avoids priming
issues with pump, as no purging is necessary
n Quicker NOx treatment and prevention of
crystallization, as urea is always present in system
n 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:
n Use potted electrical components to prevent
infiltration
n Utilize static-only sealing to avoid urea leakages
and short circuits
n Prevent crystallization by continuously keeping urea
present within the unit
