It is suitable for transporting temperature-sensitive goods such as fruits, vegetables, dairy products, meat and certain drugs that require constant temperature.
The refrigerated container is equipped with an electric (gas compressor) that is directly connected to the carrier vessel to provide power to the container for cooling or heating. This container is equivalent to a small refrigerator: the heating, cooling and defrosting functions are fully automated, and the thermostat will adjust the temperature according to the temperature range required for the loaded goods, generally at -18 ° C to -12 ° C. At the same time, the device keeps the relative humidity of the air in the tank at 85% to 95%, and the ventilation system also supplies about 50 cubic metres of fresh air per hour to maintain the best air quality.
The following are the main categories of reefer containers:
Classified according to refrigeration method
External refrigerated container：
No refrigerated device, good box insulation, a hose connector at the end of the box is connected with the refrigeration device on the ship or a ground cold storage facility to provide a source of refrigeration for the box.
Built-in reefer container：
The built-in reefer container has a refrigeration unit that is powered by a ship or onshore power supply or a self-supplied generator for the refrigeration unit.
Freezing plate reefer container：
A low temperature eutectic solution in the freezing plate provides source of refrigeration for the container.
Liquid nitrogen or dry ice refrigerated containers：
Liquid nitrogen spray or dry ice provides a source of refrigeration for containers.
The air-conditioned refrigerated container：
The air-conditioned refrigerated container controls the concentration of oxygen, carbon dioxide and ethylene in the air inside the container, inhibiting the ripening effect of the fruits and vegetables, and reduces the temperature inside the box to the desired storage temperature.
