Crowley adds 355 new PrimeLINE units

When Crowley Maritime Corporation’s liner services group takes delivery of 355 new 40-foot high-cube refrigerated containers later in 2010, it will mark the conversion of nearly a quarter of its refrigerated fleet to Carrier Transicold PrimeLINE container refrigeration units.

“The PrimeLINE unit offers improved efficiencies and reduced power consumption, which reduces our emissions and impact on the environment,” said John Azzo, Crowley’s director of strategic procurement.

The latest 40-ft high-cube refrigerated containers are also Crowley’s first to use sustainable polyurethane technology foam, an efficient insulator with lower global warming potential than conventional insulation.

“As a result of the way the container is designed and insulated, combined with the PrimeLINE unit from Carrier, we anticipate long-term efficiencies, even as the units age,” said Azzo.

Crowley dedicates most of its refrigerated containers to perishable produce transport, although Azzo said the PrimeLINE unit’s high performance at the lowest temperatures will also serve in delivery of frozen foods such as ice cream. With the recent order for 355 PrimeLINE units, Crowley will have a total of 755 of the digital scroll units in its fleet of 3,250 refrigerated containers.

The PrimeLINE unit uses digital scroll compressor technology and was developed to help shipping lines conserve fuel and reduce emissions related to shipboard power generation. According to Carrier Transicold, it has the highest deep-frozen capacity of any unit using non-ozone-depleting R-134a refrigerant.

Crowley acquired its first PrimeLINE units in 2009 after field testing in 2008.

Jacksonville FL-based Crowley Holdings Inc, a holding company of the 118-year-old Crowley Maritime Corp, is a privately held family and employee-owned company. The company provides transportation and logistics services in domestic and international markets via six operating lines: Puerto Rico/Caribbean Liner Services, Latin America Liner Services, Logistics Services, Petroleum Services, Marine Services, and Technical Services.
