This time Shipmancontainer will talk about reefer containers.

Refrigerated containers (also known as reefer containers or reefers) are containers that have usually been equipped with their own reefer machine so that the inside temperature can be adjusted to being cold or warm, anything between -35 °C and +15 °C degrees. The first reefer containers were modified from the cooling spaces of lorries and were already in use in the 1960s, but the actual reefer containers equipped with their own machines came into the picture in the 1970s.

There are also more specialized (and way more expensive) freezer containers intended mainly for laboratory use, where the temperature can be set to as much as -65 degrees Celsius or +40 degrees. Superfreezer containers are also used in shipping, especially for the transportation of more demanding fish and shellfish, so that their taste and structure will remain similar to what it was when they were captured. 

Some containers have other special features, for example, the so-called controlled atmosphere, which can be used to control the balance of oxygen, carbon dioxide and nitrogen as well as the moisture of the air. However, these are rarely seen and we will focus on the more common models in this text.

Usually refer containers are rented for food storage. For example, berry pickers and hunters use them in the summer and in the autumn for storing berries and hanging meat. Christmas hams are stored in containers during the holidays, and they have also been used for example to eliminate pests from furniture, among other things.

Temperature alone is not critical for food, as the ventilation feature of the machine has a major role for preservation. Many fruits and vegetables for example release gases that can cause the other fruit to ripen prematurely. Bananas are the largest single thing that is transported in shipping containers.

As much as 20% of all reefer shipments are banana shipments!

Reefer containers can be divided roughly into two different categories: the nowadays most common versions that have a built-in machine (which still requires electricity) and the so-called Porthole containers (also called Conair containers) that require an external machine for cooling. Porthole containers are becoming less and less popular.
