A refrigerated container (abbreviated as RF) is a container that keeps its cargo at a regulated temperature. They’re a vital component of the international cold chain and provide dependable temperature-sensitive shipping for food, medicines and electronics. Whether they’re stored or transported, reefer containers are highly versatile and can meet a wide variety of commercial and residential needs.
Unlike traditional storage containers, which have corrugated steel walls, reefer boxes have additional layers of insulation that help keep the contents cooled. In addition, they feature a refrigeration unit in the front of the container that helps to maintain the ideal temperature inside the box.
They also include special air vents on the bottom of the container that allow for cooling and ventilation. The vents allow for the refrigeration unit to circulate the cold air throughout the entire length of the container, ensuring that all products are kept at the proper temperature regardless of where they are in the box. Depending on the type of shipment, this is important because it prevents the warm or hot air from damaging the goods.
In terms of space, reefer containers are available in both 20-foot and 40-foot sizes. However, the internal space is less than that of a dry container because of the refrigeration equipment taking up some room. For this reason, it is imperative to pre-cool goods to their optimal transport temperature before loading them into a reefer container. If not, warm and moist air will enter the reefer and cause excess development of moisture that may lead to unnecessary defrost cycles and decreased efficiency of the refrigeration system.
Another key feature of refrigerated containers is their integrated data loggers that monitor power (check: reefer plugs), temperature, CO2 levels and humidity. These devices continuously register and transmit data that can be reviewed remotely. This data includes the supply and return air temperatures, remote cargo probe temperatures, defrost activity, changes to the temperature set point, and more. They also have a built-in drainage system that works to prevent water accumulation.
Many people use refrigerated containers to transport food, medicine and other temperature-sensitive items because they are so reliable. They’ve been used for decades and have a long track record of safely shipping delicate goods across the ocean.
Retail operations that sell food or drinks, like restaurants and cafes, often rent or buy reefer containers for their business locations. These containers are also commonly seen at festivals, concerts and public events where vendors want to sell their product in a cooler environment.
Another group of people that frequently use reefer containers is healthcare practitioners. These individuals need to store their medications, vaccines and other essential medical supplies in a climate-controlled environment. This is because some medicines require a specific temperature to remain effective and safe to handle. In order to keep their supplies cool and sterile, many healthcare practices look into renting or buying a refrigerated container.
