Standard ISO Refrigerated Container
The 40’ Reefer Container (ISO 42R1) is a mechanically refrigerated ISO container designed for transporting temperature-sensitive cargo. Built in accordance with ISO and CSC requirements, it maintains a controlled internal temperature throughout the supply chain and is suitable for international transport by sea, rail and road. The ISO code 42R1 designates a standard 40-foot refrigerated container.
The insulated construction and integrated refrigeration unit allow reliable transportation of frozen, chilled and temperature-controlled products while protecting cargo quality during transit.
