Latest Development News: PURINOX for Bus Retrofit

With PURINOX, Puritech presents a SCRTTM system for retrofitting of buses and refuse trucks. The objectives for the development of this aftertreatment system were based on three themes: Cleanliness – Reliability – Innovation.

Puritech engineers have used CFx – simulation tools for optimal airflow and mixing with AdBlueTM. The heat energy contained in the exhaust gas is not wasted due to a perfect heat encapsulation. With the opposing arrangement of oxidation catalytic converter and particle filter on the one hand and selective catalytic reduction converter and ammonia barrier on the other hand, the system is modular and robust.

This benchmark system is very clean, even at lowest temperatures and low load conditions. Read more about it in the PURINOX section.
