SCR catalytic converters perform the selective catalytic reduction of nitrogen oxides (NOx) from exhaust gases. The APROVIS Control System (ACS) ensures controlled and precisely coordinated dosing of the reducing agent. Further reduction of CO is achieved by means of oxidation catalytic converters, which ideally can be integrated in the SCR reactor housing. APROVIS is the manufacturer of the entire product range, which keeps the necessary costs in check and still guarantees the best service.
