The Ultimate Guide to Buying, Using, and Maintaining Refrigerated Shipping Units

In today’s global market, the ability to transport temperature-sensitive goods across long distances is crucial. That’s where reefer containers come in. These specialized shipping units are designed to maintain precise temperatures, ensuring that perishable items arrive at their destination in perfect condition. Whether you’re in the food industry, pharmaceuticals, or any other sector that deals with temperature-controlled products, understanding reefer containers is essential for your business success.

What Are Reefer Containers?

Reefer containers, short for refrigerated containers, are specialized shipping units equipped with a refrigeration system. They’re designed to transport temperature-sensitive cargo, maintaining a constant temperature throughout the journey. These containers are vital for industries such as:

• Food and beverage
• Pharmaceuticals
• Chemicals
• Flowers and plants
• Electronics

Reefer containers can maintain temperatures ranging from -65°C to +40°C (-85°F to +104°F), making them suitable for a wide variety of products.

Types of Reefer Containers

There are several types of reefer containers available, each designed for specific needs:

1. Standard Reefer Containers: These are the most common type, available in 20-foot and 40-foot lengths. They’re suitable for most temperature-controlled cargo.
2. High Cube Reefer Containers: Similar to standard reefers but with additional height, allowing for more cargo space.
3. Super Freezer Containers: Designed for extremely low temperatures, these can maintain temperatures as low as -65°C (-85°F).
4. Controlled Atmosphere Containers: These advanced units can control not just temperature but also humidity and gas levels, ideal for sensitive produce.
5. Bulk Reefer Containers: Used for transporting liquid cargo like fruit juices or dairy products.
