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 industry-leading PrimeLINE unit’s track record for energy efficiency. The EDGE option reduces energy consumption for perishable cargoes by 20 percent compared to a standard PrimeLINE unit in normal operation.
The manufacturers say that Hamburg Süd also worked with them on the development of performance optimization software that provides energy savings beyond that provided by EDGE technology enhancements, while also 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.
EDGE technology includes the following 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
“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.
