Reefer Cargo Temperature Recording

Reefer containers require special care after they are loaded on board ship. These containers need to be supplied with power, monitored closely for proper function and repaired as required in case of malfunction.The article here is about procedures and guidelines on reefer cargo Temperature Recording

A Partlow recorder registers temperature on a pressure sensitive circular chart over 31 day period. If the voyage transit is expected to exceed 31 days, care must be taken to ensure charts are replaced before expiry. The first chart should be placed under-neath the new chart in order to build up a complete temperature record for the entire voyage up until arrival at the final destination.

These charts should always carry the following endorsements:

> Name of Vessel

> Voyage Number

> Container Number

> Temperature Setting

> Load Port

> Discharge Port

> Date of Stuffing/Change

> Ventilators: Closed/Open (degrees)

> Humidity Controls (HMC) (percentage)

Data logger recorders may monitor both air and a cargo pulp temperature within a reefer unit and the data is stored in an electronic memory.

The memory also logs PTI (Pre Trip Inspection) results, alarms and transit details (e.g. shifting of the container in port). The information is more comprehensive and accurate than indicated by a Partlow chart alone.
