Products for Retrofit or Integration Into New Equipment Design
Purifilter™ employs a silicon carbide substrate and precious metal catalyst coating – providing superior performance and durability compared to traditional DPFs. Under common operating conditions, Purifilters automatically oxidize accumulated particulates.
The CombiFilter™ is a non-catalyzed Diesel Particulate Filter that is actively regenerated. On-board and off-board regeneration models are available to best suit the needs of the customers operation. CombiFilter™ is also popular in mining operations.
Purifilter™ OR is a passively-regenerating diesel particulate filter (DPF) that is compatible with a wide variety of off-road engines. Purifilter™ OR uses the same silicon carbide filter media from our other field-proven Purifilter™ models and augments it with proprietary Mixed Phase Catalyst (MPC®) technology, an upstream diesel oxidation catalyst and highly-efficient thermal insulation.
Purifilter™ Plus M
Purifilter™ Plus combines the passive regeneration of Purifilter™ with electrical heating elements that are used to periodically clean the DPF – making it an outstanding choice for both urban and highway drive cycle applications.
AZ & DZ Purifier
The AZ & DZ family of Purifiers and Purimufflers are diesel oxidation catalysts (DOCs) that reduce carbon monoxide build-up. They also cut exhaust odor by reducing hydrocarbons and soluble organics of emitted particulates – decreasing particulate matter (PM) emissions, exhaust opacity and exposure to known diesel toxins.
The Purifilter™ EGR leverages CDTi’s advanced MPC® precious metal catalyst technology on a diesel oxidation catalyst (DOC) upstream of an advanced base metal-coated DPF. This combination provides low back pressure, reduced cleaning intervals, and more than 98%+ PM reduction.
A field proven passively regenerating Diesel Particulate Filter, commonly used in mining operations since 1990. CatTrap™ features an advanced base metal soot ignition catalyst does not produce NO2 emissions while also reducing particulate by 98%+.
