What Is a Reefer Truck?
May 24, 2023

A reefer truck is another term for a refrigerated truck. Reefers are used to freight temperature-sensitive items like perishable food and beverage products. Temperature control capabilities help transport goods safely and preserve their quality, making reefer trucking a vital component of the supply chain in many industries.

What Is Reefer Trucking Used For?

Reefer trucks enable companies with temperature-sensitive items to transport cargo at the right temperature, guaranteeing items are shipped according to prescribed temperatures. This truck has a refrigerated temperature and typically runs chilled at 34-38° and frozen at -10° which is used by various industries, including food service, grocery and pharmaceutical.

Typical items reefer trucks transport include:

  • Beverages
  • Meat
  • Fish
  • Dairy
  • Frozen IQF
  • Pharmaceutical products

How Do Reefer Trucks Work?

Refrigerated trucking ensures items are transported at a specific temperature, allowing them to remain in the same condition from loading to delivery.

During reefer transportation, the unit on the semi maintains a set temperature by collecting and pumping heat, which is done through an onboard diesel-powered generator or cryogenic cooling. The refrigerated truck works on a closed system, so the fuel consumption of the trailer is not affected by how the trucker drives.

The four main components of a reefer truck are the:

  • Compressor
  • Condenser
  • Expansion valve
  • Evaporator

The parts work together to ensure the container remains climate-controlled during transportation. Reefer trucks are not designed to cool cargo — only to maintain the cargo’s temperature at the time of loading.

Benefits of Using Reefer Trucks

Reefer trucks are a crucial component of the supply chain. Their benefits include:

  • Add protection: Reefer transportation protects perishable goods against weather conditions and spoilage. Food, beverage and pharmaceutical industries rely on temperature control to ship cargo safely.
  • Ship various products: Many industries leverage refrigerated cargo transportation to ship a wide range of products.
  • Meet high demand: There is an increased demand for produce, meat, seafood, dairy, personal care and pharmaceutical products. Industries can meet the demand with refrigerated freight shipping.
  • Comply with regulations: Perishable items, chemicals and pharmaceuticals have strict temperature-control requirements. Professional reefer trucks can help ensure regulatory compliance.

Hauling Reefer Freight

To ensure perishable items remain at the required temperature, reefer truck operators and shipping companies must:

  • Monitor loading and unloading.
  • Verify the temperature is maintained.
  • Pre-set the freight trailer’s temperature.
  • Identify the various windows of acceptable temperatures for the cargo.

Additional monitoring and temperature control ensures products are protected during transport and not affected by factors like the weather.
