Did you know?
According to CARB's ruling, Carrier's EES/DPF system (required for CARB compliance) cannot be installed on units that consume lubricating oil at a rate greater than one quart per 200 hours of engine operation.  Additionally, the engine must also operate on fuel with a sulfur content of no more than 15 parts per million by weight, and no lubrication oil or other oil may be mixed with the fuel. 

Can your business afford to take that kind of risk?  Click Here for Information

Trailer TRU owners that wish to avoid the cost of compliance with the in-use standards at a later date may want to consider new TRU models that meet ULETRU.  ARB now lists the TRU models that meet the ULETRU in-use standard on the TRU Website (see link below).

Transport Refrigeration Unit (TRU or Reefer)

The Air Resources Board's (ARB) Transport Refrigeration Unit (TRU) Airborne Toxic Control Measure (ATCM) remains in effect for TRUs operating in California, including the December 31, 2009, requirements for the first phase of TRUs (model year 2002 and older). For further information on TRU ATCM requirements, please visit the website at: http://www.arb.ca.gov/diesel/tru/tru.htm or call the TRU Help Line at 1-888-878-2826.
See more information below.

Trailers moving through California must meet specific ARB requirements. Trailers may be required to have aerodynamic efficiency components.

CARB TRU  or Reefer Requirements

The California Air Resources Board (CARB) has adopted Airborne Toxic Control Measures (ATCM) for Transport Refrigeration Units (TRU) to reduce the particulate matter (PM) produced from the diesel engines. All in-use TRU units, whether domicile or operated, within the state of California must comply with this regulation by December 31, 2008 and beyond depending on unit and engine model year. Thermo King has championed technology development projects with CARB and other manufacturers to design and verify multiple retrofit options for owners and operators of TRU units. Verified Diesel Emissions Control Strategies (VDECS) are currently pending approval from CARB and will be commercially available for installation in 2006.

CARB Trailer Requirements    
The basic features of the Regulation include:

  • Compliance schedule – The Regulation is effective in 2010 and features a progressive compliance schedule that differs between small and large fleets and between new and existing equipment.
  • Standards – CARB modeled the Regulation after the voluntary standards of SmartWay. With respect to trailer aerodynamics, the regulation requires that 53' trailers must be equipped with aerodynamic technologies that have been verified under SmartWay to increase fuel efficiency by at least 5%, for dry vans, or 4%, for reefers.
  • Exemptions – The Regulation includes exemptions, notably for short-haul vehicles and non-box-type trailers.
  • Early compliance – Fleets that achieve compliance ahead of schedule receive credit toward compliance in later years. Fleets in early compliance also accelerate the benefits of fuel savings.

For more detailed information on the Regulation, please visit the Regulation website.
