Reefer trailers are a type of trailer that hauls food, perishable items or other materials in a refrigerated compartment. Reefer trailers are a type of van trailer with fixed or removable cooling units and polyurethane foam insulation. The insulation helps contain the cold so the cooling mechanism does not have to work as hard to chill the compartment. This saves on fuel costs, making it more cost efficient to transport.
Reefer trailers are used for transporting goods such as dairy products, fruit and seafood. Any perishable items that require refrigeration or freezing are hauled in a reefer trailer. These items are typically scheduled for delivery at warehouses and grocery stores; anywhere food items will be consumed or sold. Loading and unloading is done from rear doors with the use of a forklift or from the side if the trailer is so equipped. The merchandise is generally loaded with the use of pallets to assist in easy insertion into and removal from the semi trailer.
The operator of the reefer trailer must be aware of all shipping necessities. Frozen foods and refrigerated items will have different cooling requirements. The operator should be aware of what the temperature should be and ensure it is maintained for the duration of the transport. Regulating the temperature to the proper degree necessary for maintaining the items is essential. This may require additional time and attention during the shipping process. Because loading and unloading the items take special care, delays may occur. It is imperative that the temperature remains at the required state in order to keep food fresh or maintain the frozen temperature.
Reefer trailers can be purchased new or used. Shopping online to find the perfect reefer trailer will yield many results. Both new and used trailers are readily available. If purchasing a used trailer, ensure the insulation has not degraded as this will make the cooling unit work harder to chill the items. A cooling unit that has to work harder than it should will consume more fuel and drive up expenses. To prevent this, choose a type of exterior skin and interior lining that is less permeable. This will extend the life of the insulation.
