They utilize an air exchange system to maintain a continuous temperature level setup. These are the most advanced sort of reefer trailers. They utilize a control system that instantly controls the container's air exchange to maintain a needed temperature level.


Instead, they are made to preserve a particular temperature level for products. They do this by collecting and removing warm from the inside of the trailer. Refrigerated trailers utilize three core parts for their cooling system:. A tiny diesel motor powers the compressor, which pulls in aeriform cooling agent and compresses it.


As the refrigerant goes through this valve, it comes to be an amazing fluid. When in the evaporator, the fluid expands and becomes a warm gas again, absorbing the warmth and air from inside the container. This gas gets drawn right into the compressor, starting the cycle over once more. These components trigger variations in atmospheric pressure to create air movement.

It permits temperature-sensitive products to be transferred fars away. In some components of Australia, temperature levels can vary from freezing point to +40 Celsius in a matter of a couple of hours.


Reefers can be semitrailers, b-doubles, draw trailers, containers or vehicles. All that's needed is a chiller unit to cool an area that's filled.

Yet what does "reefer" represent? A chilled or "reefer" trailer is a heavily protected and snugly sealed container that has a Trailer Refrigeration Unit (TRU) mounted on the outside of the front wall, to control the temperature level inside the trailer. The primary function of a reefer trailer is to preserve the temperature level of freight at the time it is filled.


As an example, ice cream is loaded icy and the TRU maintains it frozen throughout transportation so that it is still iced up when it comes to its location. Regulating a trailer's temperature in this way helps preserve the quality and lengthen the service life of the products being transported. Reefer trailers coincide size as an average semi-trailer, meaning that they are basically 53-foot-long refrigerators on wheels
