COOL CARGOES 16 THE JOURNAL OF COMMERCE www.joc.com OCTOBER 2015 testing on the XtendFRESH technology by Eurofi ns, us- ing bananas shipped from Latin America to Scan- dinavia. Once it arrived in Europe, the produce was inspected for fresh- ness and water content, among other attributes. During the journey, a pat- ented, self-regenerating activated-carbon scrub- ber assembly captured ethylene and controlled carbon dioxide levels. As oxygen was consumed by ripening produce, au- tomated, on-demand fresh-air ventilation helped maintain the optimum level for the cargo inside. The results of the test were all the convincing Hamburg Sud needed to jump at in- corporating the technology into its fl eet. In announcing the pur- chase, Carrier Transicold President David Appel said XtendFRESH would help to expand op- portunities for the global trade of perish- able goods, and allow exporters who rely on oceangoing shipping lines to extend their reach into new markets. The new Hamburg Sud containers also use Carrier Transicold's energy- effi cient PrimeLINE refrigeration unit, bolstered with its EDGE technology to achieve even greater effi ciency. The PrimeLINE is Carrier Transicold's most energy-effi cient standard unit. EDGE is short for Enhanced Digital for Greater Effi ciency, and includes an enhanced digital scroll compressor to provide digital loading and unload- ing, a two-speed condenser motor that enables low-speed operation under light loading conditions, and a refi ned evaporator fan geometry for optimized airfl ow, the company said. When Carrier Transicold, Maersk Line and Netherlands' Wageningen Univer- sity and Research Centre's Food & Bio- based Research introduced the QUEST power-saving mode in 2007, their col- laborative effort to achieve energy-sav- ing, emissions-reducing performance did not stop. The original QUEST mode enabled power savings of up to 50 percent with some refrigeration units. QUEST II fol- lowed six years later, reducing the en- ergy required for refrigeration by up to 65 percent. Shipping lines use both software control modes today. In 2014, the company began offering FuelWise, software that cycles the refrigeration system on and off to save energy while still maintaining temperature within plus or minus 0.25 degrees C of set point on an hourly average. When reefer containers arrive at port, they need to remain in service dur- ing transport over land via truck or rail. During that time, a diesel-pow- ered portable electrical generator, or genset, is re- quired to power the refrig- eration system. To improve fuel economy of its PowerLINE gensets, Carrier Transicold intro- duced a dual-speed Fuel- Wise mode as an option several years ago. When Carrier Transicold updated the Power- LINE gensets for compliance with EPA's Tier 4 emissions requirement, FuelWise became a standard feature of the new- er RG15 "clip on" and UG15 "chassis un- dermount" models. In the gensets, FuelWise functionality provides up to 34 percent fuel savings versus previous standard units, the com- pany states. Meanwhile, one of Carrier Transicold's newest offerings is the NaturaLINE unit, which has an energy profi le similar to the PrimeLINE unit, but which uses car- bon dioxide as the refrigerant. CC — LARA L. SOWINSKI Hamburg Sud, one of the top refrigerated container carriers world- wide, recently added 400 refrigerated containers equipped with Carrier Transicold's XtendFRESH™ atmosphere control system. Carrier Transicold is a part of UTC Building & Industrial Systems, a unit of United Technologies Corp. (NYSE: UTX). To slow ripening and help preserve produce quality, the XtendFRESH system active- ly manages oxygen and carbon dioxide levels within refrigerated containers and removes ethylene.
