Refrigerated containers are used for transporting perishable goods which require a constant temperature either below or above freezing point such as fruits, vegetables, meat, dairy products, cheese and butter, seafood, poultry and ice. This type of container has special hook rails because chilled meats are sometimes transported while hanging. These containers can also accommodate goods that require standard refrigeration such as wines, beer, food platters and so much more.Click The Northern Fridgecompany.
Fruits and vegetables for transport require being stored in a modified or controlled atmosphere. This kind of atmosphere is attained by flushing the refrigerated container with CO2 and Nitrogen. While at transport, the atmosphere in the container is regulated by CO2 and ethylene scrubbers or Nitrogen flushing. These containers are kept gas tight all the time to prevent the penetration of ambient air or oxygen.
Reefers have an integral refrigeration unit that relies on external power. During transport, the container is powered through gen sets or diesel-powered generators. A redundant refrigeration system is used for transporting hazardous, temperature-sensitive and valuable goods in compliance with the regulations of the International Maritime Organization. This means a primary and back up refrigeration units are integrated into the reefer. When the primary refrigeration unit goes down, the back-up refrigeration unit automatically starts. For increased reliability, one or more diesel generators are fitted into these containers.
For short transport times, cryogenic cooling is sometimes used in these containers. In this case, liquid nitrogen or frozen carbon dioxide ice is used for cooling. The container is cooled when the cryogenically frozen gas evaporates and stays cooled as long as there is frozen gas in the system. Reefers equipped with cryogenic systems can keep the needed temperature for 30 days, making it ideal for sea transport. These reefers do not require any external power so they can be stored anywhere in the vessel that accommodates dry or un-refrigerated ocean freight containers.
A reefer comes in various sizes such as 10ft (3.048 meters), 20ft (6.096) meters) and 30ft (9.144 meters). Reefers are not only beneficial for transporting temperature-sensitive goods, they also come in handy as catering support during functions or events. These containers can keep the food safe, clean and fresh during the event. Reefers are also often used as an extra cold storage for the busy season. During the holiday season, some products are in demand such as turkey, ham, cheese and others that can be stocked and stored to meet the customer’s demands.
