What is a 20ft Refrigerated Container?
A 20ft refrigerated container is a standard ISO shipping container equipped with an integrated refrigeration system. It maintains a controlled internal climate, crucial for transporting and storing temperature-sensitive goods. These containers usually connect to a ship’s power supply or external generators. With dimensions roughly 20 feet long, 8 feet wide, and 8.5 feet high, they offer a compact yet efficient cold storage solution.
Unlike standard dry containers, reefers maintain specific temperature ranges, often between -40°C to +30°C, depending on the model. This temperature control prevents spoilage, preserves quality, and extends the shelf life of diverse products.
Types of 20ft Refrigerated Containers
Standard 20ft Reefer Containers
These are the most common reefer containers, ideal for transporting fruits, vegetables, dairy, and meat. Typically, they hold temperatures between 0°C and 23°C, accommodating both chilled and slightly frozen goods. As detailed by www.advancedcontainer.com, these units feature built-in refrigeration systems powered by ship or external electrical sources.
High Cube 20ft Refrigerated Containers
High Cube reefers offer an extra foot in height, increasing internal volume. According to containerone.net, these containers can maintain extreme temperature ranges from -40°C to +30°C, making them perfect for frozen foods, vaccines, and pharmaceuticals. Their interiors often use stainless steel for hygiene and easy cleaning.
Insulated Non-Working Refrigerated Containers
These containers lack active refrigeration but are insulated to maintain ambient temperatures for short durations. They are used primarily for temporary cold storage or to protect goods sensitive to rapid temperature changes. Both new and used options are available on the market, as highlighted by www.iport.com.
Customizable 20ft Refrigerated Containers
Some suppliers, including www.advancedcontainer.com and www.atscontainers.com, offer customizable reefers with modular shelving, racks, or partitioned spaces tailored for specific cargo needs. These units maximize space efficiency and enhance product safety during transit.
Portable Freezer Units for Specialized Applications
New reefer models serve as mobile cold storage units ideal for vaccine storage or biotech applications. www.atscontainers.com emphasizes their use during the pandemic for Covid-19 vaccine transport, with temperature ranges as low as -40°C, ensuring integrity and mobility in critical health scenarios.
Applications of 20ft Refrigerated Containers
Food and Beverage Industry
The food industry relies heavily on 20ft reefers to safely transport perishable goods. From fruits and vegetables to meat and dairy, these containers ensure freshness by maintaining precise temperature ranges. www.conexwest.com notes that commercial-grade refrigeration units by Thermo King, Carrier, or Daikin are commonly used to meet these requirements.
Pharmaceutical and Medical Storage
Temperature-sensitive pharmaceuticals and vaccines require strict thermal control to remain effective. New reefer containers with stainless steel interiors and temperature ranges down to -40°C suit this sector. www.container.com highlights their importance for long-term storage and transport of medicines.
Agriculture and Horticulture
Agricultural produce and flowers benefit from reefer containers by preserving freshness and preventing spoilage during transit. www.container.com and www.iport.com mention how temperature-controlled environments reduce waste and maintain product quality.
Chemical and Industrial Goods
Certain chemicals and industrial products demand stable, low-humidity environments to avoid degradation. Refrigerated containers with advanced insulation and humidity control, such as those from www.seabox.com, protect these sensitive materials effectively.
Temporary Cold Storage Solutions
Businesses needing short-term cold storage often turn to insulated or non-working reefers. These containers provide a cost-effective method for maintaining product quality without the need for active refrigeration. www.containerscompany.co.za offers a variety of such solutions for hire or purchase.
