Carrier develops natural refrigerant container units

March 15, 2017

Carrier Transicold has launched its NaturaLINE natural-refrigerant based system. Carrier Transicold is part of UTC Climate, Controls & Security, a unit of United Technologies Corp.

Carrier Transicold’s NaturaLINE is the first container refrigeration system to use the natural refrigerant carbon dioxide (CO2), which is a non-ozone depleting gas with a global warming potential (GWP) of one. The NaturaLINE unit uses carbon dioxide repurposed from outdoor air, according to the company. It is also unaffected by phase downs of hydrofluorocarbon (HFC) refrigerants. It is classified as A1 for low toxicity and no flame propagation.

NaturaLINE units are set to be installed by Maersk Line, a container shipping company, on 40-foot high-cube containers with delivery in the first quarter. Maersk Line will initially deploy the units on closed-loop routes between Europe and the Americas. Crew and landside training on unit operation and service is already underway.
