Latest Development News: PURINOX for UK Bus & Coach Retrofit

Following conversations with UK operators, PURItech return to the UK in 2020 with PURINOX, an advanced, credible and reliable SCRTTM system for retrofitting of buses and refuse trucks. The objectives for the development of this aftertreatment system were based on our mission to achieve 100% 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.

Continued investment in our product range development and aftersales support gives customers of PURItech a great peace of mind.

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