NaturaLINE ® Units Support TOTE Maritime's Environmental Pledge Based in Jacksonville, Florida, TOTE is the first shipping line to place a sizable quantity of NaturaLINE units into service on U.S. domestic trade routes. NaturaLINE units use carbon dioxide (CO 2), a refrigerant with the lowest global warming potential (GWP) among all refrigerants currently used in container systems. TOTE's new refrigerated containers – a mix of 40-foot and 45- foot high-cube models – were acquired via lease from SeaCube Containers LLC. They were placed into service in July, following training that Carrier Transicold provided for TOTE personnel in Jacksonville and San Juan, Puerto Rico. The NaturaLINE unit's CO 2 refrigerant, also known as R-744, has an ultra-low GWP of 1, which compares favorably against GWPs that range from 600 to nearly 4,000 for refrigerants used in other container systems. R-744 is non-ozone depleting, widely available, relatively inexpensive and classified as A1 for low toxicity and no flame propagation. "With its natural refrigerant, NaturaLINE units help fleets guard against regulations, environmental taxes and phase-outs that other refrigerants could be subject to during the operational life span of units purchased today," said David Appel, president, Carrier Transicold & Refrigeration Systems. R-744's outstanding thermal characteristics enable the energy- efficient NaturaLINE unit to achieve minus 40 degrees Celsius, along with significantly quieter operation, tighter temperature control and with no operating restrictions. Previously, reaching such a low temperature required a container system using a refrigerant with a GWP nearly 4,000 times higher than R-744. "TOTE tested NaturaLINE units in our fleet and found that in all temperature ranges, its capabilities surpassed our expectations," said Jim Wagstaff, vice president, operations, TOTE Maritime Puerto Rico. The NaturaLINE unit's deep-frozen capacity was an important factor for TOTE when considering moving cargoes, such as Further extending its commitment to environmental sustainability, TOTE Maritime Puerto Rico (TOTE) recently enhanced its fleet with 220 containers chilled by the industry's only natural refrigerant-based system, the NaturaLINE ® unit from Carrier Transicold.
