RYPOS Inc. Receives California Air Resources Board (CARB) Level 3 Plus Verification for its Hybrid Diesel Particulate Filter

CARB, the bellwether for US air quality standards, has granted RYPOS Level 3 Plus Verification for its Hybrid Diesel Particulate Filter or RYPOS HDPF/C™. Level 3 Plus Verification is based on the ability of the RYPOS HDPF/C™ to cut particulate matter (PM) emissions by 85 percent or greater while not increasing NO2 emissions by more than 20% in stationary diesel-powered emergency standby generators. CARB also granted level 3 plus verification for diesel powered pumps.

Holliston, MA (PRWEB) June 15, 2007 -- 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 HDPF/C™ filter. The Level 3 Plus CARB Verification states that during extensive tests, the filter reduced particulate matter by 85 percent or more on stationary diesel engines that power standby generators.

The RYPOS HDPF/C is designed for OEM manufacturers to retrofit 100 kW to 2 MW diesel generator set engines. In independent testing the HDPF/C not only reduced soot by 93%, but also cut nitrogen dioxide or NO2 by 96% while scrubbing particulates from the exhaust.

Since NO2 is a reactive gas associated with health problems, the California Air Resources Board (CARB) is striving to minimize it in the environment. Competing diesel engine particulate filters actually increase NO2 during the process of removing soot from emissions. California Air Resources Board has now limited that increase to 20% and, in the coming months, will withdraw its verification from filters that do not meet this standard.

In addition, The RYPOS HDPF/C™ is configured with a diesel oxidation catalyst (DOC) to reduce particulate matter by up to 90% while cutting carbon monoxide and hydrocarbon emissions as well. The HDPF/C™ is designed for newer engines using ultra low sulfur diesel fuel (15ppm). CARB also granted Level 3 Plus Verification for diesel-operated pumps typically used in farming and oilfields.

"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, a two Mega-Watt diesel power plant in South Korea and emergency stand-by generators within California including the San Jose Central Service Yard. Since California regulatory agencies influence the national clean air standards, CARB Level 3 Plus 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 Co-Founder in announcing CARB Level 3 Plus Verification.

RYPOS (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 Level 3 Plus Verification of the RYPOS HDPF/C™ covers diesel engines produced from 1996-2007 by manufacturers such as Caterpillar, Detroit Diesel Corporation, Deutz AG, Daimler/Chrysler, Motoren Fabrik HATZ GMBH, Generaco, 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 HDPF™ and HDPF/C ™ filters are now being evaluated by other diesel industry segment including the mining industry for underground applications where clean air requirements are extraordinary and within the US trucking industry for on-road transportation refrigeration units (TRU) and auxiliary power units (APU).

How it works
RYPOS filters trap soot in a sintered metal mesh resembling compressed steel wool. The filter elements are cleaned by application of an electric current that heats the metal much like a resistance heater. Competing diesel particulate filters that rely on catalysts oxidize nitric oxide (NO) converting it to NO2 by adding an oxygen atom. While NO totals remain constant, there is a potential health and environmental risk associated with increasing NO2 -- a more reactive and toxic gas than NO. CARB's limits on NO2 will become increasingly stringent, with January 1, 2009 being the deadline for meeting its 20% threshold.

RYPOS has enhanced clean diesel technology with filters that automatically regenerate - reducing pollution, fuel consumption and maintenance costs. To ensure efficient operation the RYPOS HDPF/C system can be monitored via optional Bluetooth wireless communication protocol.

CARB has assigned the RYPOS HDPF/C™ filter the designated family name of: CA/RYP/2007/PM3+/N00/ST/DPF01
