HOLLISTON, Mass. (March 2009)— The California Air Resources Board (CARB) has verified the Rypos DPF/LETRU (Level 2 Plus) diesel particulate filter for use on most trailer transport refrigeration units (TRUs) using 2002 and older model year engines. The company is now accepting orders for the new product, which provides the lowest total cost of compliance with the Low-Emission Transport Refrigeration Unit (LETRU) In–Use Performance Standard.
A highly effective self-cleaning diesel exhaust filter, the RYPOS DPF/LETRU active flow-through filter uses an electrically conductive sintered metal fiber medium and electrical power from the TRU to regenerate the filter when needed. It is microprocessor controlled with a backpressure control system, an electrical control circuit, and a backpressure warning indicator. For compliance information related to the TRU Airborne Toxic Control Measure visit http://www.arb.ca.gov/diesel/tru.htm. Rypos is also the exclusive North American distributor for the Proventia FTF, a passive flow-through filter that uses engine exhaust temperature to regenerate the filter and which is currently CARB verified to LE standards for use with Thermo King TRUs. As Rypos has a CARB verified product for both Carrier and Thermo King TRUs, mixed fleet operators can now retrofit their fleets with a single supplier.
“The RYPOS LETRU active exhaust filtration systems and the Proventia FTF passive flow through systems are the most cost efficient and effective means to meeting the California TRU emissions regulations on the market today,” comments Peter Bransfield, CEO of RYPOS.
