3.5 Route Instructions
Best practices during the route focus on minimizing the heat load entering the refrigerated
compartment.
Be aware that the Cold Plate system has a limited total refrigeration capacity. If an excessive
amount of heat enters the body during the route, the solution in the Cold Plates will thaw
completely. If the Cold Plates become completely thawed, temperature control is lost until the truck is
plugged in to run the Condensing Unit and re-freeze the Cold Plates.
To achieve best performance from the Cold Plate system:
• Product must be properly pre-cooled.
• Maintain door gaskets and door hardware for good sealing.
• Minimize the duration (time) when doors are opened.
• Minimize the number of times the doors are opened.
• Install and maintain strip curtains in the doorways.
• If using a loading dock, position the truck to achieve a good seal.
When the doors are opened, the air temperature in the refrigerated compartment will rise,
sometimes a lot. Once the doors are closed, the Cold Plates need time to cool the air back to the
design temperature. If the Cold Plate system is specified, designed, and used correctly, during
the route:
• Air temperature in the refrigerated compartment recovers to the design temperature
between route stops.
• Air temperature in the refrigerated compartment continues to recover to the design
temperature, even at the end of the route.
If the Cold Plate system is not meeting these performance indicators, it may be close to or
exceeding its refrigeration capacity. If so, first consider the best practices listed above. Also refer
to the troubleshooting guide at the end of this manual.
