xSCR + ASC Catalyst System
Advanced Diesel Exhaust Aftertreatment Solution for NOx Reduction and Ammonia Slip Control
Customized Solutions Based on Vehicle Model, Engine Specification and Exhaust System Requirements
Common Challenges in Diesel Exhaust Systems
NOx Conversion Problems
Aging or unsuitable SCR catalysts may reduce NOx conversion performance.
Ammonia Slip Issues
Excess ammonia after SCR operation may require an effective ASC solution.
Incorrect Matching
Different engines require different catalyst sizes and specifications.
How SCR + ASC System Works
01
SCR Catalyst
Copper-based SCR catalyst helps reduce NOx emissions through ammonia-based chemical reactions.
↓
02
ASC Catalyst
Ammonia Slip Catalyst helps control excess NH₃ after SCR operation.
