A refrigerate shipping container which is also known as the reefer container is the type of the shipping container used especially for the transportation of such kind of cargo which contains the refrigerated items or such items which are temperature sensitive and must be kept in specific maintained temperature. Since the refrigerated shipping containers have a cooling unit in these which work as refrigerator therefore these require power units. While these are stored on some site then the power is supplied through their reefer points by the site power plant but when these refrigerated shipping containers need to be moved then the power engine of the loader is used to keep the refrigerator on.
There are several kinds in the market of refrigerated shipping containers for sale. Each of which vary in the range of temperature these can handle. The standard range of temperature that is maintained by the refrigerated shipping containers is from -65 degrees to 40 degrees. The mechanism through which the cooling is provided to the cargo is also different. Mainly two mechanisms are used. One is the air cooling and the second is the water cooling.
Water cooling system is considered to be more expensive than the air but these are much more effective. Therefore in most of the refrigerated shipping containers the water and air cooling system is combined to reduce the heat from the cargo and to prevent the external heat from coming in the portable cool room hire.
There are several benefits of using refrigerated shipping containers. These help to move the food items and the refrigerated shipping container temperature control system help the food items to stay fresh. In this way the items are delivered to those areas in which these are not produced and the people living in that area could also eat fresh food from different parts of the globe.
There are some other kinds of refrigerated systems which are used when the circumstances are different than the usual. When the distance between the source and the destination is not very long and it will not take much time to move the cargo between two points then the cryogenic cooling system is used inside the refrigerated shipping containers. In this type the gases are used for cooling down the cargo. The common kind of gases that were used is the carbon dioxide and the nitrogen which help cooling the cargo. But the only problem is that the cargo will remain cool only for that time when the gas is present. The gas evaporates and escapes from the vent quickly and therefore it could only be used for shorter distances.
