PowerLINE generator sets
can improve fuel economy
Dec 7, 2012 9:20 AM
Helping shippers meet the challenge of rising diesel prices, Carrier Transicold’s newest PowerLINE generator sets have been enhanced with ecoFORWARD technologies, resulting in a platform capable of reducing fuel usage by about one-third versus prior standard units.
The enhanced generator sets deliver improved performance and run cleaner, while complying with 2013 Tier 4 emissions standards from the US Environmental Protection Agency.
PowerLINE diesel generator sets provide uninterrupted power to operate 460-volt ISO container refrigeration systems when used over land in intermodal applications. They are available in models that either mount underneath a container chassis or clip onto the front of a refrigerated container unit.
The 2013 models introduce:
•Standard implementation of enhanced FuelWise functionality, a fuel-saving technology that automatically switches the generator set between two speeds via a black box controller.
•A new ultra-high-efficiency permanent magnet generator (PMG).
•An optional engine emissions system for compliance with the ultra-low-emissions standard of the California Air Resources Board (CARB).
The new PowerLINE units also weigh about 14 kg (30 lbs) less than previous units.
Common to PowerLINE systems with ecoFORWARD technologies is a 2.2-liter diesel engine based on Carrier Transicold’s established engine line with its speed sensor and electronic governor.
While actual fuel consumption depends on real-world conditions, cargo, and the specific refrigeration unit used, Carrier’s preliminary testing shows the fuel savings on the new models ranges from 32% to 34%, in test situations at 38 degrees C (100 degrees F) ambient.
A fleet of 250 new PowerLINE generator sets, each operating 2,000 hours, could save in excess of $300,000 per year. Savings comes in large part from standardization of FuelWise functionality, the dual-speed capability first introduced as an option in 2008. Incremental efficiency gains also come from the 15-kw custom-designed generator. The ultra-high-efficiency PMG provides approximately 94% efficiency.
Performance gains from ecoFORWARD technologies means 20% less engine power is required, which puts the engine within the scope of EPA’s Tier 4 standard for non-highway engines rated at 8 to 19 kw (11 to 25 horsepower). The new PowerLINE units offer greenhouse gas reductions of up to 34% relative to previous standard units.
