TOTE Maritime Puerto Rico leasing 220 NaturaLINE units

The company said the refrigeration units are part of its commitment to environmental sustainability.

   TOTE Maritime Puerto Rico (TMPR) said to extend its commitment to environmental sustainability, it is enhancing its fleet with 220 containers chilled by what it says is the industry’s only natural refrigerant-based system, the NaturaLINE unit from Carrier Transicold. 
   TMPR said it is the first shipping line to place a sizable quantity of NaturaLINE units into service on U.S. domestic trade routes. 
   TMPR said NaturaLINE units use carbon dioxide, a refrigerant with the lowest global warming potential (GWP) among all refrigerants currently used in container systems. Carrier Transicold is a part of Carrier, a global provider of heating, ventilating and air conditioning, refrigeration, fire, security and building automation technologies. 
   TMPR’s new refrigerated containers — a mix of 40-foot and 45-foot high-cube models — are being acquired via lease from SeaCube Containers LLC. 
   NaturaLINE units use CO2 refrigerant, also known as R-744, which has an ultra-low GWP of 1, in comparison to GWPs that range from 600 to nearly 4,000 for refrigerants used in other container systems. R-744 also is non-ozone depleting, widely available, relatively inexpensive and classified as A1 for low toxicity and no flame propagation, TMPR said.
    TMPR said R-744’s 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, TMPR said.
   It said the NaturaLINE unit’s deep-frozen capacity was an important factor when considering moving cargoes, such as ice cream, through the tropics because of the high level of performance required to ensure optimal conditions. 
   “TOTE’s commitment to Puerto Rico is about more than reliable deliveries and exceptional customer service,” said Chris Willman, TMPR vice president of sales and marketing. “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, providing service to the island since 2015.” 
   SeaCube Containers CEO Robert Sappio said, “With this order, we are pleased to be able to help TOTE Maritime Puerto Rico in achieving its environmental goals. Through this commitment to NaturaLINE technology, TOTE Maritime Puerto Rico and SeaCube Containers are helping to advance the container shipping industry toward a more sustainable future.”
