A refrigerated transport system comprising: a body enclosing a refrigerated compartment and comprising: a pair of side walls (22C, 22D); a top; a bottom; and one or more doors (28A, 28B); and a refrigeration system comprising: a first vapor compression loop having: a refrigerant charge; a compressor for driving the refrigerant of the refrigerant charge; a first heat exchanger positioned to reject heat to an external environment in a cooling mode; and a second heat exchanger positioned to absorb heat from the refrigerated compartment in the cooling mode; a second vapor compression loop having: a refrigerant charge; a compressor for driving the refrigerant of the refrigerant charge; a first heat exchanger positioned to reject heat to an external environment in a cooling mode; and a second heat exchanger positioned to absorb heat from the refrigerated compartment in the cooling mode; a first electric fan positioned to drive a recirculating airflow from the refrigerated compartment along a first flowpath across the second heat exchanger of the first vapor compression loop; the refrigerated transport system being characterised in that the refrigeration system further comprises a second electric fan positioned to drive a recirculating airflow from the refrigerated compartment along a second flowpath (5 10B) across the second heat exchanger of the second vapor compression loop; and in that the one or more doors are at a first end of the body; and the refrigeration system is mounted in an equipment box at a second end of the body opposite the first end; and in that the first and second flowpaths are isolated from each other or are adjacent halves of a single flowpath. a body enclosing a refrigerated compartment and comprising: a pair of side walls (22C, 22D);
