The main porpouse of the reefer containers is to keep the goods at a constant temperature between -25ºC and + 25ºC avoiding peaks that could damage the products. Although this is sufficient for the majority of products, others require lower temperatures or other conditions, which may require the use of more specific types of reefers, so we can find:
- Reefer container: with a margin of +/- 2ºC, within a temperature range of -25ºC to +25ºC.
- Super freezers:These reefers are equipped with a more powerful refrigeration unit and more efficient insulating material, which means goods can be kept at temperatures of up to -60ºC. This type of reefer is very much in demand for shipments to and from Japan (tuna, sword fish, etc.) and for some pharmaceutical products.
- Controlled atmosphere: These reefers can maintain a specific atmospheric pressure. This is useful, for example, to control the ripening process of fruit transported in a reefer. Some of these containers can also provide high humidity conditions.
- Ventilated containers: These shipping containers are fitted with thermal insulation and refrigeration units that provide excellent ventilation. They are the perfect solution for products such as onions, potatoes, garlic and coffee.
