Maersk Line has ordered the first 100 of a total of 200 refrigerated containers to be equipped with Carrier Transicold’s NaturaLINE natural-refrigerant based system.
NaturaLINE is a more environmentally friendly solution as it is the first container refrigeration system to use the natural refrigerant carbon dioxide, a safe and non-ozone depleting gas with a global warming potential (GWP) of one.
Unlike traditional systems, since the NaturaLINE unit uses carbon dioxide repurposed from outdoor air, there is no added global warming impact resulting from potential refrigerant leaks.
According to company, the system, which is relatively inexpensive, is also unaffected by phase downs of hydrofluorocarbon (HFC) refrigerants and classified as A1 for low toxicity and no flame propagation.
The NaturaLINE units are currently being installed on 40-ft high-cube containers with delivery scheduled for the first quarter of 2017.
Maersk Line is expected to initially deploy the units on closed-loop routes between Europe and the Americas.
Ingrid Uppelschoten-Snelderwaard, head of global equipment at Maersk Line, said: “To meet our sustainability goals and stay ahead of the new EU legislation, Maersk Line is keen to carefully evaluate all alternatives to the current synthetic refrigerants.
“The NaturaLINE system is an advanced technology with interesting potential for reefers. We chose it after laboratory testing of the unit’s performance with perishable and frozen commodities and look forward to gaining further operational experience with the system.”
