Are you planning to transport goods that require temperature control? Then there’s a high probability that you have come across the terms ‘reefer’ and ‘insulated container’ during your research. Although many people tend to use these terms interchangeably, the truth is that they are different from each other. So, what’s the actual difference between a reefer and an insulated container?
To start with, both a reefer and an insulated container are designed to provide temperature control during the transportation of goods. However, the primary difference lies in the way they achieve this temperature control. An insulated container simply protects the goods from extreme temperatures in the surroundings, while a refrigerated container or ‘reefer’ actively regulates the temperature within the container.
So, if you are transporting goods that require a specific temperature range, such as meat, dairy products, or pharmaceuticals, a reefer is your best bet. On the other hand, if you are moving goods that need to stay at a constant temperature, such as chocolates or wine, an insulated container will do just fine. Knowing which type of container you need can save you a lot of money and headaches, as well as ensure that your goods arrive at their destination in perfect condition.
Definition of Reefer and Insulated Containers
When it comes to shipping goods that require temperature control, two common container types to consider are refrigerated or reefer containers and insulated containers. Though they might seem similar, reefer and insulated containers have distinct features for different types of products. It’s critical to understand which one suits your product requirements better.
- Reefer containers: Also known as refrigerated containers, reefers are specially designed to maintain a specific temperature, either chilled or frozen, for transporting perishable goods. These containers come with a built-in cooling system, which is regulated by the container’s thermostat that ensures the temperature is kept within the desired range. It is cooled by a motor compressor that operates on an external power source, usually provided by the shipping line, and can maintain the temperature between -25°C to +25°C, regardless of the outside temperature. These are ideal for shipping pharmaceuticals, meat, fish, fruits, and vegetables.
- Insulated containers: In contrast, insulated containers are primarily designed to provide resistance to varying temperature conditions. They have two layers of insulation, which ensures that the internal temperature remains stable for a more extended period. They do not have any refrigeration equipment installed, and they rely on the product’s thermal properties to maintain the internal temperature. They are ideal for shipping items that are not perishable but still require stable temperature conditions, such as electronics, chemicals, and industrial parts.
In conclusion, the choice between a reefer and an insulated container is critical and relies primarily on the type of product being shipped. It’s essential to understand the product’s temperature requirements, how long it will be in transit, and the potential external temperature variations. This information will help determine which container type is best suited for your product shipping needs.
