Ammonia slip catalyst (ASC)

Mobile emissions control: Johnson Matthey’s ASC technology removes residual ammonia (NH3) from upstream ammonia dosing systems, converting it into nitrogen (N2) and water (H2O).


VOC catalysts

The catalyst used in our Emission Control System is based on platinum (Pt). This catalyst reduces the amount of volatile organic compounds (VOCs) in the exhaust gas by 99.8%, i.e. to levels well below the legal limits.


HAPGUARD monitor

Stationary emissions control: Johnson Matthey's HAPGUARD temperature and pressure monitor ensures that your catalytic converter remains in compliance with RICE NESHAP for clean air.
