All our reefer containers are bottom-air delivery. This means that the cold air is supplied from the bottom of the container through the specially designed T-bar floor and side walls.

1) Buffer Plate

  • Located at back of reefer
  • To provide a guide for air flow circulation
  • Cause of damage of buffer plate if missing : causing airflow short cycle, froze damage, heat exposure to area where air flow are weaken

2) Power Sockets (plugs)

  • All PIL reefers are using Cee-Form plugs. Do not tamper with these reefer plugs as electrocution may occur
  • Pins are often cut, especially if they are using incompatible female plugs


Digital recording of ambient temperature near produce or product temperature if probe are fully inserted into product

3) Probes (Upon Request)

  • 3 methods of putting the probes
  • Into produce
  • Into vent hole carton box
  • Taped to the outside the carton box

4) Partlow Chart

  • With effect from Sept 2005, PIL has stopped installing of partlow chart recorder on our new reefer fleet purchase. All temperature readings will be retrieved via data logger. New reefer build will no longer come with partlow function and older reefer with partlow function will be replaced with decal explanation


5) Ventilation

  • The ventilation of fresh, chilled products is necessary in order to remove the RESPIRATION gas, carbon dioxide and ethylene produced by the cargo. Heat is removed by continuously circulating the internal air, whereas carbon dioxide and other gases are MINIMISED by introducing fresh air into the fresh air circulation.

Closed air vents during land transit

  • For any land transfer that requires the refrigerated container to be off power, it is suggested to customer to close the air vents for refrigerated containers carrying fruits/vegetables
  • This is to avoid any pollutants/contamination (eg: diesel fumes) that may enter the container via the air vents during the land transport
  • However, air vents must be re-opened to the required setting when the reefer machinery is being switched on subsequently upon arrival at CY terminal. Hence all stations/respective parties are required to check the vent settings are in accordance to shipper’s requirements
