TOTE Maritime Puerto Rico is leasing 220 new reefer boxes with Carrier Transicold’s CO2 refrigerant.
Carrier Transicold has announced another breakthrough for its NaturaLINE reefer system, the only reefer machinery on the market today to use the natural refrigerant CO2 to achieve a Global Warming Potential (GWP) of one.
TOTE Maritime Puerto Rico (TMPR) will lease the 220 new reefer boxes, a mix of 40-foot and 45-foot high-cube models, through SeaCube Containers. “TMPR is the first shipping line to place a sizeable quantity of NaturaLINE units into service on U.S. domestic trade routes,” Carrier said.
CO2 refrigerant, also known as R-744, is the only refrigerant available today with an ultra-low GWP of 1. Carrier notes that other refrigerants in use today have GWPs “that range from 600 to nearly 4,000”. In addition, “R-744 is also non-ozone depleting, widely available, relatively inexpensive and classified as A1 for low-toxicity and no flame propagation,” added Carrier.
“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.
With regard to performance in field, Carrier said: “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”. This is a reference to R404A, which is used today by Thermo King.
TOTE Maritime Puerto Rico said NaturaLINE could meet its needs, including shipping ice cream through the tropics. “TMPR 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’s commitment to Puerto Rico is about more than reliable deliveries and exceptional customer service,” added Chris Willman, vice president sales & marketing, TOTE Maritime Puerto Rico. “It’s about leading the industry with best-in-class, environmentally sustainable products, such as NaturaLINE refrigeration units and our emissions-reducing Marlin-class vessels, the first containerships efficiently powered by liquefied natural gas (LNG), providing service to the island since 2015.”
SeaCube Containers, one of the world’s largest purchasers and lessors of refrigerated containers, has thrown its support behind NaturaLINE and CO2, and the order will be the third that SeaCube has placed for NaturaLINE reefers. “With this order, we are pleased to be able to help TOTE Maritime Puerto Rico in achieving its environmental goals,” said Robert Sappio, CEO, SeaCube.
