Running temperature controlled freight in peak summer heat comes down to getting a few basic dock procedures right every single time.
☑️ Pre-cool the trailer before loading
Loading cold product into a warm trailer creates instant condensation and spikes internal box temperatures right at the start.
☑️ Pulp test the product on the dock
Checking and recording the actual internal product temperature on the bill of lading protects you from inheriting damage that happened before loading.
☑️ Keep air channels clear around the load
Air needs to circulate all the way to the back doors, so stacking freight too tight or blocking the re**er chute stops proper cooling.
☑️ Set the re**er to continuous run mode
Auto start stop settings save a little fuel, but high risk loads need constant airflow to maintain a steady temperature throughout the trailer.
☑️ Inspect door seals and track temps in real time
Worn door gaskets let hot ambient air leak inside, which forces the unit to work overtime and increases your risk of a breakdown.
Re**er units are really built to hold temperature rather than pull down warm product, so taking five minutes to verify these details on the dock saves everyone from a massive claim later.
