Recycling depots use many types of mobile machinery for handling waste material. The machines are equipped with special cabin filtration systems and particulate filters. The duty cycle of these machines can vary depending on what materials are handled in the depot.
Johnson Matthey DPF systems, such as electrical and CRT® systems, can be installed on wheel loaders, excavators and cranes to reduce particulate matter as required by local regulations.
These systems are normally suitable for use with industrial wheel loaders, shredders, screens, chippers and multihandlers operating in recycling.
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 at least 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®). 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.
