BlueMAX™ NOVA-Series (SCR+ADPF+DOC)

The BlueMAX™ NOVA-Series from Nett Technologies combines Selective Catalytic Reduction (SCR), an Active Diesel Particulate Filter (DPF) and a Diesel Oxidation Catalyst (DOC) to control PM, NOx, CO and HC from medium and heavy-duty diesel engines, for both original equipment and retrofit.

How it works

The system comprises the SCR catalytic converter, a computerised Urea Dosing System, urea tank, DPF, DOC and control components. A NOx sensor upstream of the SCR, combined with engine air mass flow and temperature sensors, lets the controller calculate the required urea (32.5% solution) dose, so no engine mapping is needed and the system suits both mechanically and electronically controlled engines. An ammonia slip catalyst is standard. The active DPF achieves filtration efficiency above 90% even at low soot loads.
