# Malfunction Detection Systems in Reefer Cargo

*Last updated: 2026-06-25*

> Reefer containers integrate malfunction detection systems that monitor temperature, humidity, and refrigeration-unit parameters – compressor pressure, fan status, door seals – around the clock.

Reefer containers integrate malfunction detection systems that monitor temperature, humidity, and refrigeration-unit parameters – compressor pressure, fan status, door seals – around the clock. Any deviation from set points triggers an immediate alert to onboard systems or shore-based control centres, allowing crews or remote operators to intervene before perishable cargo such as fresh produce, seafood, or pharmaceuticals is compromised. These systems are standard practice in international maritime reefer transport and are a prerequisite for the unbroken cold-chain records required for pharmaceutical shipments. They should not be confused with malfunction diagnostics, which identifies the root cause of a fault after it has occurred.
