“Urea Water(DEF) Additive that Decomposes

   Accumulated Urea Crystals at Room Temperature”

SCR system failure is a major issue for domestic diesel cars, often caused by urea crystal accumulation. Other causes include disconnection, short circuits, and sensor failures, but the buildup of urea crystals remains the most common problem. Currently, in Korea, the root cause of SCR system failure is not accurately diagnosed, leading to expensive part replacements as the only solution.

The SCR Cleaning Urea Water (DEF) Additive addresses this issue by decomposing accumulated urea crystals at room temperature when mixed with urea water. These crystals are then removed through normal combustion. This additive can resolve urea warning light issues without the need for extensive maintenance and helps extend the life of the SCR system through consistent injection management.

“At a ratio of 10:1, hard crystals are

completely dissolved in 8 to 12 hours”

The urea water additive effectively dissolves urea crystals that are resistant to removal, even with hot water, within a short period of time through a chemical reaction with urea decomposition. Most crystals are completely dissolved within 12 hours, blending seamlessly with the urea water.
