Carrier Transicold units help cut emissions

Energy-efficient container refrigeration systems introduced by Carrier Transicold in recent years are playing a vital role in helping the marine shipping industry strengthen its environmental profile.
Carrier Transicold, which in 2014 celebrated production of its one-millionth container refrigeration system, reports that total global sales of its PrimeLINE unit, introduced in 2007, has topped 250,000 units. Compared with prior models, the PrimeLINE unit is significantly more efficient, which reduces shipboard electricity demand and emissions related to power generation. This results in a 28% reduction of carbon dioxide equivalent emissions.
“Over their projected life, our PrimeLINE systems account for a savings of more than 12 million tons of carbon dioxide—the same as removing 200,000 cars from the road,” said David Appel, president, Carrier Transicold & Refrigeration Systems. “Our environmentally sustainable portfolio of container refrigeration equipment can help shipping lines reduce their carbon emissions.”
To this end, Carrier Transicold’s recently introduced NaturaLINE unit has a similar energy profile to the PrimeLINE unit, but uses the natural refrigerant CO2 instead of a synthetic refrigerant. CO2 has a global warming potential (GWP) of one compared with R-134a, which is used in most other container refrigeration systems and has a GWP of 1,430; and R-404A, which has a GWP of 3,922 and is used in a smaller share of container systems.
“By offering an energy-efficient system using a natural refrigerant that delivers high refrigeration capacities, we provide the shipping industry with a viable hedge against procurement challenges or cost increases related to phase-outs of higher GWP synthetic refrigerants, which have been targeted by multiple governments and environmental agencies for a variety of applications,” said Appel.
The PrimeLINE and NaturaLINE units are also the first and only container refrigeration systems to achieve validation by UL Environment for recyclability—93% for the PrimeLINE unit and 95% for the NaturaLINE unit.
