How do Refrigerated Transport Trucks Stay Cold

The movement of consumable items from the manufacturer sites to the retailers requires caution to avoid spoilage. Refrigerated transport trucks are used to deliver consumable foods like raw meats, frozen dairy products (yogurt, ice cream, sherbet, milk, sherbet, etc.), and frozen dinners to ensure their freshness.

How Food Stays Fresh in the Refrigerated Transport Trucks

Even long distances will not get your fresh products stale when travelling in refrigerator trucks. To maintain the temperature inside, these trucks use ice and other schemes, making the produce still fresh. Its inside walls are lined with hard blocks of ice. The main part is left open where products requiring a cool environment are stored. Onboard cooling systems that look like the one found in your home refrigerator are used. Carbon dioxide is even used in some trucks to minimize and sustain the temperature inside the trailer.


To have a space for foam insulation, there are voids at the back of the walls and under the aluminum floor of refrigerator trucks. The voids on the floor provide an area to install foam, providing structural support for cargo, which are very sturdy and durable.

Refrigerated transport trucks are not only ideal for foods requiring a specific temperature range when stored. Other items can also be transported using these trucks. These include medical supplies like: a) drugs that need regulated temperature control; and b) organs for transplants. These items are kept inside the refrigerator trucks when transported.

Refrigerator trucks are also utilized by archaeologists when shipping artifacts, so they remain intact when submitted for evaluation in museums or research facilities.

The doors of these trucks are kept close to maintain the right temperature needed by the items inside. The summer months pose risk to the perishable items inside the refrigerator trucks if the doors are left open for even just an hour: This exposes the items inside the truck to all the outside elements, particularly heat.

When dealing with a refrigerator truck transport service, specify that there should be no short drop offs and pickups when your products are inside the truck. Verify with the provider that the vehicle is up-to-date with its maintenance. There should be appropriate insulation, which is the R-value (Thermal Resistance) to promote cold, chilled and frozen cargo.

How these refrigerated transport trucks maintain the temperature is a big question. Keeping the temperature depends greatly on the number of times the doors of the vehicle were opened and on the outside temperature.

With Avrio Logistics, perishable items reach their destination as fresh as they were taken from the manufacturer’s sites. Refrigerated transport truck drivers follow a routine schedule of keeping the inside temperature with no short stops and drop offs and with reduced opening of the truck doors.
