Emitec is supplying retrofit system manufacturer Cleaire with next-generation diesel oxidation catalyst (DOC) technology. Both companies conducted research and development work to create a more compact and robust exhaust emissions system. Emitec’s LS (longitudinal structure) catalyst design uses small shovels to break up and redistribute the exhaust flow inside its channels, improving overall catalyst efficiency. The supplied catalysts will be used for Cleaire's Allmetal particulate filter systems for off-highway applications, including wheel loaders, tracked machines, graders, and excavators, which are smaller and need less precious metal than current conventional catalysts. The Allmetal Level 3+ retrofit system reduces tailpipe diesel particulate matter by more than 85%, according to the company. Under the agreement, catalysts are supplied from Emitec’s manufacturing facility in South Carolina.
