Kossah workers perform after-sales service KSC staff after-sales service

In the previous after-sales activities, the SCR nozzle cleaning agent was used by Kossau staff to clean the area of ​​the SCR system that was prone to crystal scaling, and continued to receive praise from users. However, many users also reflected that in addition to SCR nozzles, urea tanks in the SCR system are also very prone to crystal scaling, and it is hoped that the company will be able to introduce relevant cleaning products.

Under the strong demand of the majority of users, Kosan has introduced a new product of urea box cleaner and used it in the Urumqi Post's Guosan car for this after-sales service, achieving significant cleaning results. The SCR nozzles, urea tanks, etc., which were originally surrounded by crystalline dirt, have been completely renovated and exposed. The postal workers have all raised their thumbs.

With the national five standard to be implemented nationwide in 2017, more and more vehicles using the SCR system will face urea crystal scaling. At present, there is no place dedicated to SCR system maintenance on the market. Once the vehicle is over-protected, the SCR system faces no maintenance and can only be replaced. The four-nation five-system solution provided by Kosalin can provide professional SCR system maintenance after-sales service to avoid the frequent replacement of the SCR system, which greatly saves user costs.
