| The advanced filter technology from Rypos  Rypos has been selected to install its newly developed active diesel particulate filters on heavy-duty construction vehicles operating at the Croton Water Treatment Plant in The Bronx. Rypos’ advanced technology enables the filters to automatically clean themselves or regenerate irrespective of engine temperatures. The advanced filter technology removes up to 90% of the soot and gases emanating from diesel engines and automatically clean themselves or regenerate without needing high exhaust gas temperatures or human intervention.This makes them ideal for construction vehicles that run at intermittent duty cycles or in remote environments and fail to sustain temperatures that are hot enough to passively burn off accumulated soot from their exhaust filters. The Rypos filters eliminate routine filter servicing and maintenance costs as well. Unlike filters that depend on engine heat to regenerate, Rypos filters automatically regenerate using electrical current. The Rypos ADPF/C, combines banks of sintered metal filter elements that resemble compressed steel wool and are conductive with a diesel oxidation catalyst. When the filters need regeneration, pressure sensors signal the microprocessor-controlled system to automatically send current through the metal fibers to heat them and burn off accumulated particles – much like a self-cleaning oven. The trucks’ 24-Volt battery bank provides power. The Rypos ADPF/C reduces particulate matter by up to 90%, while cutting carbon monoxide and hydrocarbon emissions as well and is designed for newer engines using low sulfur diesel fuel. Another product, the Rypos ADPF is designed for older diesel engines operating on high-sulfur fuel. This product achieves total particulate matter reduction exceeding 60 percent and is suited for areas where low sulfur fuel is unavailable. This technology has received California Air Resources Board Verification for stationary diesel engines powering standby generators. The Rypos filter well exceeded CARB’s Level-2 emission standard of 50% particulate matter reduction during testing. write your comments about the article :: © 2006 Construction News :: home page |
