Container Refrigeration Energy Efficiency Yields Good Returns

Refrigerated container specialist group Carrier Transcold reports record sales of its PrimeLINE 'fridge' container product

Reflecting the shipping industry's continued trend in the adoption of energy efficient equipment that reduces lifecycle costs, Carrier Transicold reported that its PrimeLINE® container refrigeration unit has surpassed previous records, selling nearly the same number of units in 2011 as in the prior three years combined.

The PrimeLINE unit's exceptional efficiency -- thanks in part to its efficient digital scroll compressor -- significantly reduces on-board power generation requirements, helping shipping lines save fuel used in the generation of electricity. This, in turn, helps hold down operating costs and reduce emissions related to power generation. The PrimeLINE unit reduces carbon emissions 28 percent compared to previous units.

As fuel is the leading component of ownership cost over the life of a unit, energy efficiency helps to keep the total cost of ownership low. In addition to its exceptional efficiency, the PrimeLINE unit also offers best-in-class pulldown among all container refrigeration units, as well as best deep-frozen capability among those that use R-134a, the non-ozone depleting refrigerant with the lowest global warming potential of all contemporary container refrigerants. No other container refrigeration unit provides dehumidification capability lower than the PrimeLINE unit, and none can achieve 50 percent relative humidity as efficiently claims this manufacturer.
