RYPOS Diesel Particulate Filters Enable Refrigerated Trucking Industry to Meet California TRU Regulations

By Eco News Network

The only company offering a complete line of diesel particulate filters designed  to retrofit existing refrigerated transport trailers, RYPOS is working closely with trucking firms to meet the newly enforceable California TRU emissions regulations.

The regulations moved forward with the January 19th ARB waiver by the U.S. EPA allowing the state to enforce the reduction of toxic diesel emissions from tens of thousands of refrigeration units mounted on big rigs.

The California Air Resources Board (CARB) regulations require all approximately 40,000 TRU engines on the road in California, including those traveling from outside the state, to have emission control technology that is less than seven years old.  For model year 2001 and older TRUs, the compliance date is July 19, 2009.

“The RYPOS LETRU active exhaust filtration systems and the Proventia FTF passive flow through systems reduce harmful particulate matter emissions around trucking facilities, protecting the health of trucking industry employees and those who work in and around the trucking industry,” comments Peter Bransfield, CEO of RYPOS. “These retrofit devices are the only viable systems available on the market today and are the most cost efficient and effective means to meeting the California TRU emissions regulations.”

A highly effective self-cleaning diesel exhaust filter, the RYPOS LETRU uses electrical power from the TRU to regenerate the filter when needed. This unique, new product will be CARB verified to Low Emission (LE) standards for Carrier Transport Refrigeration Units (TRUs). The Proventia FTF is a passive wall flow filter that uses engine exhaust temperature to regenerate the filter.  Exclusively distributed in North America by RYPOS, it is currently CARB verified to LE standards for use with Thermo King TRUs.

The LE CARB Verification states that during extensive tests, the filter reduced particulate matter by 50 percent or more on transport refrigeration units utilizing diesel engines. According to the CARB, diesel particulate matter was listed as a toxic air contaminant in 1998 triggering a requirement to reduce public exposure. Toxic air contaminant classification are compounds found to cause or contribute to deaths or serious illness, or pose a present or potential hazard to human health. Diesel PM constitutes 70 percent of the airborne carcinogens in California’s air. Once fully implemented in 2020, the California regulation will eliminate 2,000 tons of diesel particulate matter emitted into California’s Air.

RYPOS Inc. is a privately held company with operations in Holliston, Mass., and Long Beach, Calif. Founded in 1996 by a distinguished group of scientists and entrepreneurs, RYPOS has spent the past several years developing, testing, and bringing to market advances in diesel particulate filter technology. RYPOS’ pioneering efforts have led to the creation of proprietary control circuitry, four U.S. patents, and one pending patent application. The company’s leading edge products for diesel exhaust filtration utilize patented electrical regeneration strategy and technology.  The flexible and scalable designs have applications in on-road, off-road, stationary, and marine markets.
