Reefer Telematics

Reefer telematics is the remote monitoring and control of refrigerated containers, transmitting setpoint, supply and return air temperature, humidity, controlled-atmosphere gas levels, power status, and alarms over cellular, satellite, or onboard power-line and wireless links to a shore dashboard. It lets a single operator watch hundreds of boxes, intervene on a temperature excursion before cargo loss, and prove the cold chain for perishables and pharmaceuticals. Onboard, the data routes through ship power-management and a gateway rather than constant satcom; the function reduces the manual reefer-round labor and the spoilage claims that drive perishable-cargo disputes.
