An optional new engine emissions system (EES) for Carrier Transicold's latest PowerLINE® generator sets received full verification from the California Air Resources Board (CARB) as a level 3+ verified diesel emission control (VDEC) device. Carrier Transicold helps improve global transport and shipping of temperature-controlled cargoes with a complete line of equipment for refrigerated trucks, trailers and containers, and is a part of UTC Building & Industrial Systems, a unit of United Technologies Corp. (NYSE: UTX).
Carrier Transicold now offers a verified engine emissions system for PowerLINE RG (top) and UG generator sets used in California
"Full verification validates the EES as an evergreen compliance solution for CARB's particulate emissions standard for transport refrigeration units (TRUs) and TRU generator sets used in California," said Michael Dormer, general manager, Global Container Services, Carrier Transicold.
As an option for California applications, the system can be specified for PowerLINE generator sets concurrent with sale or lease. However, it is specifically designed for easy installation at a later time for users who require extended CARB compliance.
"The ability to decide to install upfront or defer the installation to a later time gives customers greater flexibility in determining how and when to invest in their fleets' emission upgrades," Dormer said.
CARB's full verification of the EES is a significant milestone in Carrier Transicold's rollout of its latest generator sets, providing shipping lines and leasing companies with technology options and compliance choices that best suit their unique operations. Last November, CARB granted conditional verification to the EES, allowing its installation on PowerLINE generator sets with up to 3,000 hours of engine operation. Achieving full verification removes the 3,000-hour condition, permitting EES installation regardless of accrued hours of operation.
The EES is the first and only original equipment manufacturer-developed CARB level 3+ VDEC device for generator sets. A level 3+ VDEC device reduces particulate emissions in accordance with CARB's ultra-low emissions requirement for transport refrigeration units, also known as ULETRU, while also reducing nitrogen oxides.
The EES was engineered for Carrier Transicold's PowerLINE clip-on and undermount TRU generator sets, which provide uninterrupted power to operate 460-volt ISO container refrigeration systems when hauled over land in intermodal operations. These TRU generator sets are certified to the U.S. Environmental Protection Agency's (EPA) 2013 Tier 4 standard for engines rated under 25 horsepower, allowing use indefinitely throughout North America and for up to seven years in California without restriction. In California, CARB uniquely requires that a VDEC strategy be applied to units in this class when used for more than seven years, which is provided by the EES option.
"CARB's robust verification process requires independent testing and diligent review by CARB staff to assure fleets that verified products meet stringent durability, performance and emissions-reduction specifications,” Dormer said. "Carrier Transicold worked closely with CARB staff to advance the EES to ensure reliable emissions reduction on models equipped with Tier 4 engines and achieve full verification."
Installed in place of the standard exhaust system, the EES filters exhaust using a high-performance diesel oxidation catalyst (DOC) and a unique catalytic diesel particulate filter (CDPF). The DOC removes over 93 percent of hydrocarbons and the CDPF eliminates over 98 percent of particulate matter, well beyond the 85 percent ULETRU requirement. Carrier Transicold's EES uniquely uses a combination of passive, active and active-assist regeneration to clear accumulated soot. No operator intervention is needed.
Carrier Transicold's PowerLINE generator sets for Tier 4 compliance incorporate ecoFORWARD™ technologies, resulting in a platform that can reduce fuel usage by approximately one-third compared with prior standard units, which were designed for compliance with the EPA's 2008 Tier 4 interim, or Tier 4i, standard. Those models are still available worldwide, with or without a FuelWise™ fuel-saving option, for use in markets where the Tier 4i standard meets or exceeds local emissions requirements.
