Challenge
Thirty-seven billion pounds of bananas are shipped globallyeach year, making bananas the world’s most popular
produce. Bananas are consumed in every country on earth,but are grown in few by comparison, so they must travel
thousands of miles before arriving in the local store.
Successfully transporting bananas is no easy task. As soon
as bananas are harvested, they are placed into a refrigerated
container while still in the field and brought to 58.0°
Fahrenheit (14.4° Celsius).
After that, they are hauled by truck to port, placed onto aseagoing vessel, transferred to a refrigerated warehouseat the receiving port, and then transported by refrigerated
truck again to the store. If the temperature drops even afew degrees below the ideal temperature at any time during
this process, the banana skin will develop dark spots and will
not ripen properly. If the temperature rises a few degrees,premature ripening and shrinkage occurs.

Solution
Modern refrigerated seagoing containers equipped with
Emerson’s Copeland Scroll Digital™ compressor technology
provide precise temperature and humidity control, whichhave been shown to maintain temperature to within +/0.5° F (+/- 0.3° C). This is particularly critical for perishable
products – like fruits and vegetables – which travel inseagoing containers on vessels that encounter harshweather conditions and require tight climate control toprotect quality. In the food industry where profit margins are
narrow, any product degradation due to poor temperatureand humidity control during transport is a significant
financial concern.

Emerson estimates that use of its energy-efficient digital
scroll compressors in refrigerated containers can enable thebanana industry to save more than $10 million in fuel costs
and reduces shrink and spoilage by $500 million annually.
In addition, they reduce carbon emissions related to bananatransportation by 15 percent.
Food shippers like Dole and many others have found that
Emerson’s Copeland Scroll compressor technology helps
them better protect their valuable perishable products, saveon energy costs and deliver environmental benefits.

Dole, the world’s largest producer and marketer of fresh
fruits and fresh vegetables, switched almost exclusively tothe use of refrigerated container systems equipped with
Copeland Scroll Digital compressors in 2005. Dole relieson Emerson’s technology to rapidly remove heat from thecontainer. At the point of harvest in the field, the digital
scroll compressor ‘pulls down’ the temperature to theideal level, and enables a 46 percent more energy efficientmethod for maintaining temperature control throughout
the remainder of the bananas’ journey.
