Hamburg Süd, one of the top refrigerated container carriers worldwide, has ordered 6,500 new containers equipped with Carrier Transicold’s PrimeLINE refrigeration unit featuring the new energy efficiency-boosting EDGE technology option. EDGE, which stands for Enhanced Digital for Greater Efficiency, includes a set of design enhancements that improve on the PrimeLINE unit’s track record for energy efficiency. The EDGE option reduces energy consumption for perishable cargoes by 20% compared with a standard PrimeLINE unit in normal operation. “With a proportionately large investment in refrigerated containers, Hamburg Süd was eager to work with Carrier Transicold on ways to further push the PrimeLINE unit’s boundaries of efficiency, which already has a reputation for high energy savings as well as best-in-class refrigeration performance,” said Chiou Fun Sin, president, global container refrigeration, Carrier Transicold. Hamburg Süd also worked with Carrier Transicold on the development of performance optimization software that provides energy savings beyond that provided by EDGE technology enhancements, while maintaining narrow temperature-control tolerances for carrying perishable cargo. The software is included with the new Hamburg Süd units, which are being installed on 20- and 40-foot high-cube containers being used for fleet replacement and expansion.
“Over the past several years, the PrimeLINE unit has made an increasingly important contribution to our sustainability initiatives,” said Frank Smet, a member of the Executive Board, Hamburg Süd. “The efficiency improvements provided by PrimeLINE with EDGE technology are consistent with our philosophy on stewardship, which compels us to continuously improve our fleet operations for the good of the environment. With the EDGE technology advantage, less fuel consumed for shipboard energy production to operate our refrigeration units will translate into reduced carbon emissions from power generation.” EDGE technology includes these design enhancements over standard PrimeLINE units: •Digital scroll compressor optimization—providing both digital loading and unloading and other enhancements that reduce energy demand •Two-speed condenser motor—enabling operation at low speed during lighter load conditions •Refined evaporator fan geometry—providing optimized air flow via an enhanced fan profile and fine-tuned blade pitch As a premium option for PrimeLINE units only, EDGE technology will be broadly available in 2014, and can be specified with or without the new performance optimization software.
