Refrigerated trucks, also known as reefer trailers, are an insulated freight shipment method for perishables and temperature sensitive products. Most reefer trailers are 53-foot-long attachments to semi-trucks and are powered by diesel engines. The cooling system in each unit contains a compressor, condenser, and evaporator that work hard to ensure cold temperatures. Refrigerated trailers also include air delivery chutes to help circulate the cold air.

Refrigerated Box Trucks and Van Sizes
The range of refrigerated box trucks and vans caters to various cargo sizes and transportation needs. Some of the standard sizes are:
12’-14’ Trucks:
Ldeal for small-scale deliveries, these trucks can carry 4-6 pallets, supporting loads between 5,000 to 7,000 lbs. Perfect for local, urban deliveries of fresh produce or pharmaceuticals.
16’-20’ Trucks:
This is a mid-size option capable of handling 6-8 pallets with a payload capacity of up to 13,000 lbs. It is suitable for medium-sized businesses distributing goods across regions.
22’-28’ Trucks:
Designed for heavy-duty hauls, these trucks accommodate 10-12 pallets and payloads between 9,000 and 15,000 lbs. They are the go-to for large-scale, long-distance deliveries of frozen foods or temperature-sensitive cargo.

Parts of a Reefer Truck or Trailer
Compressor: On a truck unit, the compressor often attaches to the engine and uses a small motor or vehicle belt system to power the entire unit by drawing in gaseous refrigerant and compressing it. The gas enters the system as a low-pressure, cool fluid and exits as a high-pressure, hot gas.
Condenser: After passing through the compressor, the high-pressure gas goes through condenser coils and loses its heat via a fan-based cooling system. The condenser absorbs heat from the cargo section and uses it to form gas once enough heat is absorbed. The gas inside the condenser is condensed and liquidized due to the pressure, leaving as a high-pressure, regular-temperature liquid.
Expansion valve: The expansion valve is instrumental in the reefer container truck process, as it regulates the refrigerant’s flow throughout the system. When the valve restricts the flow of the refrigerant, the molecules expand and result in a low-pressure, cold liquid.
Evaporator: The evaporator is located in the truck’s cargo section and changes the low-pressure, cold liquid into a low-temperature, low-pressure gas. The evaporator fan pulls room-temperature air from the cargo department over the evaporator coils and fins to circulate it throughout the trailer. Refrigerant going through the evaporator will boil and change into a gas, as it has a low boiling point. Afterward, the gas returns to the compressor and repeats the process until the system reaches the desired temperature.
Insulation: A layer of polyurethane foam throughout the entire trailer protects the truck’s interior from the outside environment.
