Difference Between Reefer Truck and Reefer Trailer: Understanding Your Cold Transport Options

In the world of transportation, the logistics industry relies on specialized equipment to get the job done. Among the key players are reefer trucks and reefer trailers, each with distinct features and functionalities suitable for different needs within the refrigerated transportation sector.

Both serve the crucial role of preserving perishable goods during transit, be it food, pharmaceuticals or flowers, by providing a controlled temperature environment.

The difference between reefer trucks and reefer trailers, though sometimes subtle, affects our decisions on which to utilize for specific transportation needs. A reefer truck is an integrated vehicle composed of a cab and a refrigerated cargo area, often used for shorter trips or more localized delivery routes. Due to their compact nature, they offer greater maneuverability than their larger counterparts.

Reefer trailers, however, are separate cargo containers that can be attached to a semi-truck for hauling. These are generally preferred for hauling significant volumes of goods over long distances, offering the flexibility of being detached and left at a distribution center, while the truck moves on to other tasks.

Our selection between a reefer truck and a reefer trailer hinges on various factors such as the load size, the distance of travel, and access to loading docks.

With the primary goal of maintaining the cold chain intact, we meticulously evaluate each option to ensure that our perishable and temperature-sensitive goods are transported efficiently, securely, and within the optimal temperature ranges regardless of external conditions.

Understanding Reefers

In the logistics industry, we often encounter reefer trucks and reefer trailers as vital resources for transporting perishable goods. They are essential for maintaining the quality and safety of temperature-sensitive products during transit.

Definition of Reefer Trucks and Trailers

Reefer trucks are vehicles with a built-in refrigeration unit designed for the transport of perishable goods. They have insulated walls and a self-powered refrigeration system that controls the temperature inside the cargo area. This integrated setup provides excellent maneuverability and quick access to freight.

Reefer trailers, on the other hand, are large containers that can be attached to a truck cab. They also contain built-in refrigeration units and insulated walls, but unlike reefer trucks, they require an external power source from the truck cab to maintain temperature control during transportation.

Key Characteristics of Reefers

Our focus on reefers centers around their capacity to manage temperature control, humidity, and airflow to protect goods such as food, flowers, and pharmaceuticals. The core components of a reefer include:

• Compressor: The heart of the refrigeration system, which circulates refrigerant and absorbs heat from the cargo area.
• Evaporator: Works to remove the warm air and lower the internal temperature.

These units must ensure stable temperatures, which can range from below freezing to just cool, depending on the cargo’s requirements. Even minor fluctuations in temperature can compromise the integrity of temperature-sensitive cargo.

Both reefer trucks and trailers typically have similar insulation and refrigeration capabilities. However, the choice between using a reefer truck or a reefer trailer often depends on the specific needs of the cargo, including the size and distance of the shipment.

Differences in Design

When we discuss the differences between reefer trucks and trailers, it’s essential to understand that their design reflects their specific uses. Reefer trucks are integrated units designed for accessibility and maneuverability, whereas reefer trailers are meant for larger-capacity transport and are attached to a truck cab.

Structural Variations

Reefer trucks and trailers have distinct structural differences. Reefer trucks are typically shorter in length, offering greater maneuverability for dense urban environments where navigating tight spaces is common. Their lengths can range from shorter lengths comparable to a box truck to those approaching the size of trailers, but they maintain a high degree of flexibility due to their integrated design.

On the other hand, reefer trailers are designed to be towed by a truck cab and provide various sizes. For instance, large reefer trailers are usually between 48 to 53 feet in length and can accommodate larger loads. Smaller variations, known as Pup trailers, may range from 20 to 25 feet, suitable for shorter distances and smaller cargo quantities. This variance in size directly impacts their cargo-carrying capacity.

Regarding materials, reefer trailers may use extensive foam-based insulation, which can add significant weight—up to 1,000 pounds of excess compared to a dry van. Consequently, both reefer trucks and trailers can carry less payload than an unrefrigerated dry van, as part of their gross weight must account for the refrigeration apparatus.

Refrigeration Mechanics

The refrigeration systems within reefer trucks and trailers share some common elements but are implemented differently due to their design. Both systems typically involve a compressor, condenser, and evaporator coil—the fundamental components to generate and maintain a cold environment for temperature-sensitive freight.

Reefer trucks have a refrigeration unit integrated within their structure, often located at the front of the cargo area. These units are more compact given the smaller size of the truck and are designed for ease of access and frequent opening and closing, which is typical for delivery routes with multiple stops.

Reefer trailers, in contrast, have larger refrigeration units that must cool a greater volume of space. Their refrigeration mechanics are built to sustain heavy-duty operations and hold consistent temperatures over longer distances and durations, which is critical for cross-country transport of perishable goods.
