Rypos Awarded Texas State Grant to Test its Advanced Air Pollution Technology on Dallas -Fort Worth and Houston-Galveston Diesel Generators

Massachusetts Developer of Advanced Diesel Filter Technology is Part of $7.5 Million Clean Air Research Program in Texas --- Rypos’ active regeneration technology is a vast improvement over passive ceramic filters that require high exhaust temperature. When the sintered-metal filter cartridges at the heart of the Rypos system need to be cleaned or regenerated, a microprocessor sends an electric current through the conductive filter element to heat it and burn off soot -- much like a self cleaning oven.

Rypos has been selected to receive a Texas state grant to test its advanced diesel engine emission filters for their ability to cut air pollution from engines used to generate electricity and run oil and construction industry equipment.

Rypos’s evaluation will include both laboratory tests and field evaluations in the Dallas/Fort Worth and Houston/Galveston areas. The Texas Commission on Environmental Quality (TCEQ) grant is part of the Texas Emission Reduction Plan, aimed at reducing NOx and particulates from diesel fueled vehicles and equipment in Texas. The goal includes cutting Nitrogen Oxide emissions by up to 40 percent.

Rypos will conduct the tests under the aegis of the Houston Advanced Research Center, a not-for-profit research management firm in Woodlands, Texas. HARC is charged with administering $7.5 million in state grants aimed at reducing Nitrogen Oxide emissions from diesel engines. The Texas Environmental Research Consortium (TERC), made up of state and local leaders who focus in East Texas air quality, approved the grants. TERC’s goal is to advance air quality science so that policymakers and regulators can make sound decisions.

Rypos established its reputation as a technology leader for cutting soot or particulate matter (PM) from diesel engine emissions and has received California Clean Air Resource Board (CARB) Verification for its Advanced Diesel Particulate Filters (ADPF™). The proprietary filters automatically regenerate or “self clean” and cut total particulate matter by over 60 percent.

Rypos Hybrid Diesel Filter to be Evaluated

In addition to removing soot or PM, Rypos developed a hybrid filter that reduces both PM and Nitrogen Oxide from diesel exhaust. The Hybrid Diesel Particulate Filter (Rypos HDPF/NOx) will be used in the tests. The filtration systems will be monitored during normal operations and NOx emissions will be measured and quantified. Tests will be based on plans developed with EPA’s Environmental Technology Verification program and California Air Resource Board. Verification will enable RYPOS to deploy the NOx treatment system for the retrofit market, according to state environmental officials.

In 2001,the Texas Legislature established the Texas Environmental Research Consortium (TERC) and its New Technology Research and Development Program (NTRD) to facilitate development, certification and verification of new technologies for broad and economical clean air applications.

Rypos Technology

Rypos’ active regeneration technology is a vast improvement over passive ceramic filters that require high exhaust temperature to work, which is not always possible in cold climates or when engines run intermittently. When the sintered-metal filter cartridges at the heart of the Rypos system need to be cleaned or regenerated, a microprocessor sends an electric current through the conductive filter element. The current heats the metal element and regenerates the filter by burning off accumulated particles. Efficiency is remarkable, less than a 1% fuel penalty to regenerate the filters – far lower than competing systems.

In addition to custom filters and applications, Rypos developed and manufactures two product lines -- the CARB-Verified Rypos ADPF™ and the Rypos ADPF/C™. Both filters are designed for OEM manufacturers and to retrofit engines ranging from 100 kW to 2 MW. The Rypos ADPF™ is designed for older diesel engines operating on high-sulfur fuel.

The Rypos ADPF/C™ is configured with a diesel oxidation catalyst (DOC) to further reduce the soluble organic fraction, hydrocarbons, and carbon monoxide. Soot, or particulate matter reduction ranges as high as 90% with the Rypos ADPF/C™

CARB Verification covers diesel engines produced from 1996-2007 by manufacturers such as Caterpillar, Detroit Diesel Corporation, Daimler/Chrysler, Komatsu, Iveco, Deere, Perkins, Volvo Penta, Cummins, Daewoo, GMC, Nissan Diesel, Mitsubishi, Isuzu, Kubota, Lombardini Motori, Scania, International Trucks and numerous others.

RYPOS, Inc. (http://www.rypos.com), 260 Hopping Brook Road, Holliston, MA 01746-1455 is a developer, manufacture and marketer of advanced self-regenerating filters for diesel engines. In addition to diesel generators, pumps, construction equipment, locomotives and marine vessels, the Rypos ADPF™ and ADPF/C ™ filters are being evaluated by the mining industry to meet stringent underground clean air requirements.
