1. Market Background

With the South Korean Ministry of Environment (KMOE) continuously tightening emission standards for commercial vehicles and heavy machinery, the demand for Aftertreatment System (ATS) maintenance has surged. In this context, the catalyst cleaning and refurbishment industry has become pivotal in reducing operational costs. Korean clients prioritize physical dimensional precision and durability under repetitive cleaning cycles when selecting suppliers.

2. Customer & Application Scenario

The client in this case is an established Catalyst Cleaning Specialist in South Korea. Their core business involves clearing clogs and restoring performance for DPF/SCR systems in trucking fleets, buses, and construction machinery. Due to the diverse range of vehicles they service, the client requires a stable, long-term supply of various catalyst components to replace units damaged by carbon sintering or thermal aging.

3. Our Solution

To meet the demand for "multi-model, long-term cooperation," we provided a parameterized product matrix covering mainstream Euro V/VI standards, ensuring precise fitment with original vehicle systems.

Key Technical Parameters:

• SCR Catalyst: Dimensions Ø326×150 mm. This substrate offers excellent space velocity adaptability, ensuring high conversion efficiency during denitrification.

• DOC Catalyst: Dimensions Ø115×155 mm. It features a low light-off temperature to provide stable thermal energy for downstream DPF regeneration.

• DPF Substrate: Dimensions Ø285×240 mm. The wall-flow substrate ensures efficient PM filtration while maintaining extremely low exhaust backpressure.

   

4. Customer Feedback & Summary

Feedback indicates that since establishing long-term cooperation, our SCR, DOC, and DPF components have achieved zero error in installation fitment. Notably, the substrates remain structurally sound with no coating delamination even after multiple professional cleaning cycles, significantly extending the service life of the ATS.

Summary: By providing precisely parameterized products (such as Ø326×150 SCR) and consistent technical support, we have helped our Korean client build a reliable reputation in the competitive Catalyst Cleaning Industry.
