Refrigerated Trailer| Small Portable Freezer-Cooler Trailers

A refrigerated trailer is commonly referred to as a “reefer” trailer or a “refrigerated van.” These trailers are designed to transport perishable goods, such as food, pharmaceuticals, and other temperature-sensitive items, by keeping them at a specified temperature range. The interior of a reefer trailer is equipped with a refrigeration unit that cools the air inside the trailer to maintain the desired temperature.

The lifespan of a refrigerated trailer can vary depending on factors such as the quality of the trailer, the frequency and intensity of use, and the maintenance it receives. A basic 115 volt refrigeration unit is less expensive and easier to maintain since any basic refrigeration mechanic in your area can service. With proper care and maintenance, a refrigerated trailer can last between 10 to 20 years or even longer.

A refrigeration unit is typically mounted on the front of the trailer, and it is powered by either an electric, gas or diesel engine.
Here’s how a refrigerated trailer works in a nutshell:

1. Cooling system: The refrigeration unit uses a cooling system that typically contains a compressor, condenser, evaporator, and refrigerant.

2. Temperature control: The temperature inside the trailer is controlled by a thermostat, which sends signals to the refrigeration unit to adjust the temperature as needed.

3. Air circulation: A fan inside the trailer circulates the cooled air to maintain a consistent temperature throughout the trailer.

4. Insulation: The walls, ceiling, and floor of the trailer are insulated to help keep the cooled air inside and prevent warm air from entering.

5. Power source: The refrigeration unit is powered by either an external power source, such as an electric outlet or a generator, or by a diesel engine mounted on the front of the trailer.

When the refrigeration unit is turned on, the compressor compresses the refrigerant gas, causing it to become hot. The hot gas then flows through the condenser, which cools the gas and turns it back into a liquid. The liquid refrigerant then flows through the evaporator, where it absorbs heat from the air inside the trailer, cooling the air down. The cooled air is then circulated throughout the trailer by the fan, and the process is repeated as needed to maintain the desired temperature.

Overall, a refrigerated trailer works by using a refrigeration unit to control the temperature inside the trailer, allowing perishable goods to be transported at a consistent, controlled temperature.

The most common power sources for refrigerated trailers are:

1. Diesel engine: Many refrigerated trailers are equipped with a diesel-powered refrigeration unit that is mounted on the front of the trailer. This type of system is often used for long-haul trucking, where the trailer needs to be self-sufficient and able to operate for extended periods without access to external power.

2. Electric power: Some refrigerated trailers are designed to be powered by an external electric power source, such as a wall outlet or a generator. This type of system is often used for short-term storage or transport of goods at a fixed location, such as a distribution center or a loading dock.

3. Hybrid power: Some refrigerated trailers use a combination of electric and diesel power sources. These trailers have a diesel engine that powers the refrigeration unit when the trailer is on the road, but can switch to electric power when the trailer is parked or connected to an external power source.

4. Natural gas: There are also some refrigerated trailers that use natural gas as a fuel source for their refrigeration units. These systems are still relatively rare, but they offer a more environmentally friendly alternative to diesel power.

In summary, refrigerated trailers can run on diesel, electric power, hybrid power, or natural gas, depending on the specific needs of the operator and the application of the trailer.

Here are some rough estimates of the cost range of different types of refrigerated trucks:

1. Small vans: New Small refrigerated vans can cost between $75,000 to $120,000. These vans are typically used for local deliveries of small quantities of perishable goods, such as flowers, baked goods, or pharmaceuticals.

2. Medium-sized trucks: New Medium-sized refrigerated trucks, also known as “reefers,” can cost between $115,000 to $175,000. These trucks are often used for regional or long-haul transportation of larger quantities of perishable goods, such as food, produce, or pharmaceuticals.

3. Large trucks: New Large refrigerated trucks can cost between $125,000 to $250,000 or more, depending on the size and features. These trucks are typically used for long-haul transportation of large quantities of perishable goods.

It’s important to note that the price of a refrigerated truck is just one factor to consider when purchasing one. Other factors to consider include insurance costs, operating costs, maintenance costs, fuel efficiency, and resale value.

Also, prices can vary based on location, manufacturer, and customizations requested, so it’s best to research and compare prices from different manufacturers and dealers to get the best deal.
