How do Refrigerated Trailers Work?

Refrigerated trailers, also known as refrigerated vans or reefers, work by using a refrigeration unit to cool the interior of the trailer to a specific temperature. The refrigeration unit, which is typically powered by a diesel engine, circulates a refrigerant through a system of coils and compressors to lower the temperature inside the trailer. The cooled air is then circulated throughout the trailer using fans, and the temperature is regulated using a thermostat. Insulation in the walls, floor, and ceiling of the trailer helps to maintain the desired temperature even when the trailer is parked or moving. This allows perishable goods such as food, medical supplies, and other temperature-sensitive products to be transported over long distances without spoiling.

What is a refrigerated trailer called?

A refrigerated trailer is also called a reefer trailer or a refrigerated van.

Why do they call it a reefer trailer?

The term "reefer" is short for "refrigerator" and is a colloquialism that has been used in the trucking industry for many years to refer to refrigerated trailers. This usage likely originated because "reefer" is a shorter and more easily pronounced word than "refrigerator," and it is a catchy term that is easy to remember. The term is also thought to be influenced by the fact that reefers typically transport perishable goods, such as fruits and vegetables, that are often referred to as "reefer cargo."

How long can a refrigerated trailer run?

The length of time a refrigerated trailer can run depends on several factors, including the size and efficiency of the refrigeration unit, the amount of insulation in the trailer, and the ambient temperature outside. A typical refrigerated trailer's refrigeration unit can run for several hours on a single tank of diesel fuel, depending on the size of the tank. Some units have a holding time of around 24 hours, so the refrigeration unit does not have to be running all the time, but runs on specific intervals to keep the temperature steady. Insulation in the trailer helps to maintain the desired temperature for longer periods of time, even when the refrigeration unit is not running. When the refrigeration unit is running, it can be affected by the ambient temperature outside, the higher the temperature outside the more the refrigeration unit has to work to maintain the desired temperature inside the trailer. It is important to note that a refrigerated trailer should be used in accordance with the manufacturer's recommendations to ensure the safe and efficient operation of the refrigeration unit.

What fuel does a refrigerated trailer use?

The refrigeration unit, also called a refrigeration unit or a reefer unit, is typically powered by a small diesel engine that runs on the fuel from the truck's fuel tank. The diesel engine powers a compressor that cools a refrigerant which circulates through the refrigeration unit and cools the air inside the trailer. Some of the modern refrigerated trailers have electric standby option, which allows them to be powered by an electric generator or shore power when parked, in order to maintain the temperature inside the trailer and reduce fuel consumption.

How cold can a reefer trailer get?

A reefer trailer, or a refrigerated trailer, on average, can typically reach temperatures as low as -20°C (-4°F) or lower, depending on the type of refrigeration unit used and the insulation of the trailer. The temperature inside a reefer trailer is usually adjustable and can be set to a specific temperature, depending on the type of goods being transported. Powerful refrigerated trailers can go as low as -30°C (-86°F)  and are equipped with a thermostat that allows the operator to adjust the temperature as needed. Some reefer trailers are also equipped with a temperature monitoring system that allows the operator to check the temperature inside the trailer remotely, and make adjustments as necessary. It's important to note that temperature requirements vary depending on the type of goods being transported and it's essential to follow the guidelines set by the manufacturers or the industry standards.
