Rypos Inc. Granted California Air Resources Board (CARB) Verification for its Advanced Diesel Particulate Filter

Share Article

CARB, the bellwether for US air quality standards, has granted Rypos Level 2 Verification for its Advanced Diesel Particulate Filter or Rypos ADPF™. Level 2 Verification is based on the ability of the Rypos ADPF™ to cut particulate matter (PM) emissions by 50 percent or greater in stationary diesel-powered emergency standby generators. CARB also granted conditional verification for pumps and other applications. The Rypos ADPF works on Tier 1 Engines, fuel with up to 500 PPM sulfur, 2-cycle diesels, and has no minimum exhaust temperature requirement.

Rypos, Inc., developer of an advanced, self-regenerating filter that reduces harmful emissions from diesel engines, has been granted California Air Resources Board (CARB) Verification for its Rypos ADPF™ filter. The level 2 CARB verification states that during extensive tests, the filter reduced particulate matter by 50 percent or more on stationary diesel engines that power standby generators and run on high sulfur fuel -- fuel with up to 500 ppm of sulfur.

The company’s two product lines are the now CARB-Verified Rypos ADPF™ and Rypos ADPF/C™. Both filters are designed for OEM manufacturers and to retrofit 100 kW to 2 MW engines. The Rypos ADPF™ is designed for older diesel engines operating on high-sulfur fuel. During CARB tests, The Rypos ADPF™ well exceeded the Level 2 Verification standard by reducing total particulate matter by more than 60%.

In addition, the Rypos ADPF can be configured with a diesel oxidation catalyst (DOC) for further reductions of the soluble organic fraction, hydrocarbons, and carbon monoxides.

CARB also granted conditional verifications for diesel-operated pumps typically used in farming and oil-fields.

“Our advanced filters are already being deployed in applications as diverse as two-stroke marine engines on US NAVY vessels, earth moving equipment at a major public works project in the Bronx, NY and a two MegaWatt diesel power plant in South Korea. Since California regulatory agencies influence the national clean air standards, CARB Verification is a major milestone in our company’s development. It will further expand market opportunities for our products -- both in the US and internationally,” said Klaus Peter, Rypos president and CEO in announcing CARB Verification.

Rypos’ (http://www.rypos.com) active regeneration technology is a vast improvement over passive ceramic filters that need high exhaust temperatures to regenerate, which is not dependable when engines run intermittently or in cold climates. The proprietary technology relies on banks of sintered metal filter elements. When a microprocessor senses that the filters need regeneration, it automatically sends an electric current through the conductive fibers to heat them and burn off accumulated particles.

CARB Verification of the Rypos ADPF™ covers diesel engines produced from 1996-2007 by manufacturers such as Caterpillar, Detroit Diesel Corporation, Deutz AG, Daimler/Chrysler, Motoren Fabrik HATZ GMBH, Generac, Komatsu, Navistar, Iveco, Deere, Perkins, MTU, MITF, Volvo Penta, Cummins, Daewoo, Hino, Case, GMC, VMMI, JCB, Yanmar, Nissan Diesel, Mitsubishi, Isuzu, Kubota, Lombardini Motori, Case, Scania AB, KUKJ, CNH Engine Corp, Power Systems, MITF, and International Trucks.

In addition to auxiliary and backup generators, pumps, off-road vehicles including locomotives and marine engines, the Rypos ADPF™ and ADPF/C ™ filters are now being evaluated by the mining industry for underground applications where clean air requirements are extraordinary.

CARB has assigned the Rypos ADPF™ filter the designated family name of: CA/RYP/2005/PM2/N00/ST/DPF01
