MEDITERRANEAN Shipping Company (MSC) is to lease 2,000 containers from SeaCube Containers that are chilled by Carrier Transicold's innovative, natural refrigerant-based NaturaLINE refrigeration system. The NaturaLINE refrigeration units use carbon dioxide as a refrigerant, which has a much lower global warming potential (GWP) than other refrigerants. In addition to their environmental benefits, Giuseppe Prudente, chief logistics officer at MSC, said the units provide a 'higher level of performance in the minus 40 degrees Celsius deep-frozen range. We can add new capabilities for our growing customer base, particularly for seafood and other high-value frozen commodities.'

Previously, minus 40 degrees Celsius was only attainable in container systems using a refrigerant with a GWP nearly 4,000 times higher, reports American Shipper.
