Johnson Matthey is a leading supplier of retrofit diesel emissions control systems for non-road machinery.

Agriculture


Johnson Matthey offers a range of diesel retrofit exhaust technologies which can easily be fitted on many makes and types of agricultural machinery such as tractors, ploughs and combine harvesters.

CRT® & CCRT® system

These systems are normally suitable for use with a wide range of agricultural machinery, engine power ranges and engine emissions levels. This depends partly on how hard the engine is working during the normal operation of the machine as this affects the exhaust gas temperature which needs to be above a certain level for 50% of the time for these systems to regenerate reliably.

The other factor is the balance of NOx to particulate level in the exhaust gas, which is often determined by the certified emissions level of the engine. The CCRT® system has the filter coated with catalyst as well as having a Diesel oxidation catalyst (DOC) in front of the filter (as in the CRT® system). This extends the operating window of the filter system to allow reliable regeneration with lower exhaust temperatures or lower NOx to particulate ratio in the exhaust gas. Our specialists can advise which system is most suitable for your specific application.
