arbcombo -- Expand the Rypos DPF/ULETRU Verification to include Carrier Multi-Temperature TRUs Posted: 05 Sep 2017 13:35:54
The California Air Resources Board (CARB) has modified the RYPOS DPF/ULETRU Diesel Particulate Filter System verification to include the Carrier multi-temp Transport Refrigeration Units (TRU) equipped with model year 2003 and newer off-road diesel engines rated at up to 50 horsepower. The Rypos DPF/ULETRU is a Level 3+ diesel emission control strategy (DECS), capable of reducing emissions of particulate matter (PM) by 85 percent or more without increasing nitrogen dioxide emissions to more than 20 percent of total nitrogen oxides. The RYPOS system consists of a diesel oxidation catalyst (DOC), an active exhaust filter and an automatic filter regeneration system. Specific engine models and families that may qualify are listed in the Engine Family List at CARB's Verification Procedure Website for the Rypos DPF/ULETRU at: http://www.arb.ca.gov/diesel/verdev/companies/rypos/uletru.htm Rypos has completed all of the requirements for this verification update, including extensive field demonstrations, showing reliable backpressure control. To qualify for retrofit with the Rypos DPF/ULETRU, TRU engines must be maintained in accordance with the engine and original equipment manufacturersí specifications and meet all of the pre-installation compatibility assessment criteria established for the Rypos DPF/ULETRU. Other terms and conditions for which the Rypos DPF/ULETRU has been approved may be found in CARBís Executive Order at CARB's Verification Procedure Webpage for the Rypos DPF/ULETRU at: http://www.arb.ca.gov/diesel/verdev/companies/rypos/uletru.htm Additional information about the Rypos DPF/ULETRU may be found at Ryposí webpage: http://www.rypos.com/resources-2/brochures/ As indicated above, the Rypos DPF/ULETRU is a Level 3+ DECS, which meets CARBís TRU Regulationís Ultra-Low-Emission TRU (ULETRU) in-use performance standard. All model year (MY) 2009 and older TRUs and TRU gen set engines must meet ULETRU now. MY 2010 TRU engines must meet ULETRU by the end of 2017. Engine repowering is no longer a compliance option for MY 2008 and newer engines because replacement engines that fit and perform are no cleaner than the old in-use engines being replaced. Retrofitting with a Level 3 VDECS is a compliance option that is less costly than replacing the entire unit. Where can I get more information?
