Loading & Delivery Best Practices for Refrigerated Units

ReeferReflectedthumb7

  • Pretrip your truck/trailer before pre-cooling and loading product:
    • Initiate an automatic pretrip to identify any operational concerns while the reefer cycles through all of its modes.  Do not load trailer if alarm codes indicate service is needed.
    • Inspect the condition of the truck/trailer, noting any damage to the insulation, door seals, and defrost drains.
    • Clean inside of truck/trailer.  To prevent contamination hazards and blockage of airflow, the floor channels and refrigeration unit air stream must be free of debris.
       
  • Pre-cool truck/trailer:
    • Always pre-cool truck/trailer to the temperature of the product to be loaded.  Doing so will remove unwanted heat from the truck/trailer walls, floor and ceiling.  Remember refrigeration units are not designed to lower product temperature. 
       
  • Load product with the proper loading pattern:
    • Product should be loaded quickly and efficiently using the proper loading patterns that maximize air circulation around and through the product load.  Product should never be loaded tightly against the evaporator housing, doors, walls, ceiling, or tightly against other pallets of product.  All six sides of all pallets should be exposed to airflow. 
       
  • Delivery Practices:
    • Inspect strip curtains (if used), report any damage to your supervisor.
    • Be certain reefer unit is off when opening doors, reefers will pull in warm, humid air if the door is left open while the unit is running.
    • Minimize door opening duration to further reduce this intake of warm outside air.  Remember, the longer the doors are open, the longer it will take to regain the proper temperature.
    • Move product quickly when delivering to cross dock locations.
